Chapter 2 Introduction

Chapter 2 Introduction 2.1

Objectives of this unit This unit performs non-contact measurement of the distance (gap) between the FL sensor and the measured object (target), and outputs a voltage signal corresponding to the gap. By combining this unit with our monitor, it is possible to measure the vibration of a rotating shaft, its eccentricity, thrust position, rotating speed etc. The unit is utilized for continuous measurement or monitoring of shafts rotating at high speeds, in turbines, generators, compressors, etc. This unit is not designed for use in any other applications.

2.2

Measurement principles The gap between the FL sensor and the target is found according to the following principles. •

If an approximately 1MHz high frequency current is supplied from the oscillator in this unit to the FL sensor, a high frequency magnetic field is created at the FL sensor.

•

By the interlinkage of high frequency magnetic flux in the target, an eddy current will flow on the target surface.

•

When the eddy current flows on the target surface, a magnetic field is created at the target side, and the sensor impedance will change.

•

The output of the oscillator is detected, and the distance vs. output voltage is made linear by a linearizer electrically, and the result is output.

Therefore, if the following relationships are identified in advance, it is possible to find the gap between the FL sensor and the target by measuring the sensor impedance: •

Recommended specifications for the monitor cable Use a commercially sold cable to connect the unit and the monitor. A CVVS 3 core shielded cable (straight) is recommended, but if it is not available, a 3 line multiple core cable for light electrical instruments (individually shielded) can be used. Use cables of sizes AWG. No.20 to 16 (0.5mm 2 to 1.25mm2). Cable name

Note

CVVS 3 core shielded cable (straight)

The CVVS 3 core shielded cable is also recommended in the API STANDARD 670. Recommendation: Copper tape shield (core wire; soft copper wire) (Normally, silver plated braid) Use conduit pipe (cable rack) for wiring.

3 line multiple core cable for light electrical instruments (individually shielded)

Recommendation: Outer shield is aluminum tape, copper tape shield The multipair cable can contain a mixture of vibration signals and displacement signals. However, vibration signals for a high amplitude vibration can affect other vibration signals and displacement signals negatively, and these need to be wired on a separate cable.

Chapter 3 Installation 3.1.2

FL sensor installation environment Install the FL sensor at a location that satisfies the following environmental and install conditions.

▊ Environmental conditions ▊ •

Ambient temperature: Must be in a range between -35 to 117 °C when devices are operating.

•

Vibration conditions:

Must be 10m/s2 or less at 10 to 150Hz. (If the sensor vibrates, an accurate measurement cannot be made.)

Other environmental conditions are the same as the content described in “3.1.1 FK driver installation environment” (  Page 19).

▊ Installation conditions ▊ •

Do not install at a location exposed to rain or other moisture. It can lead to reduced sensitivity of the FL sensor, and reduced insulation.

•

A target surface area of 15 mm dia. centered on the FL sensor is required.

•

When placing other FL sensors next to each other, separate the sensor tops by 40mm or more. If they are placed too close together, the FL sensors will interfere with each other.

•

The FL sensor must be installed on a surface with adequate rigidity, that will not be affected by an outside vibration. If the FL sensor vibrates, an accurate measurement will not be possible.

•

For shapes and dimensions around the FL sensor, refer to the installation example 1-3 below. If a piece of metal other than the target is near the FL sensor, an accurate reading will not be possible. If it is unavoidable to install the FL sensor in the methods of installation examples 4 to 7, check the characteristics at the attachment completed conditions. Installation example 1 (most recommended) Dimension X is to be 9mm or more.

Installation example 2 (recommended) Dimension X is to be 9mm or more. Dimension Y is to be 15mm or more.

Gap adjustment Point

After completing all wiring connections, it is possible to perform gap adjustment using a tester. In this case, make sure to fully understand the content described in this chapter and complete all connection work, then perform gap adjustment according to the procedures in “3.4.5 Set gap voltage confirmation”(  Page 31).

Adjust according to the following procedures.

1

Refer to “5.1 Standard static characteristics” ( Page 35), and prepare a gap gage matching the gap that will produce the desired characteristics. Consider the following items for the gap. Set the gap so that even when the ● target is at the nearest point to the FL sensor, the target will still not come into direct contact with the FL sensor. Set the gap so that it will not go beyond ● the linear range of the connection monitor.

2

Being careful not to scratch the sensor top and target surface, insert the gap gage between the sensor top and target.

3

Adjust the FL sensor to a position where the gap gage just moves freely, and affix in place with the jam nut. Tighten the jam nut with the following torque. Model

3.4

Wiring connections WARNING ●

Make sure the wiring and connections are performed by a person with knowledge in instrumentation.

●

Always perform grounding. Never apply power until all wiring work and connection work has been completed. If this is not followed there is a possibility of electrocution.

ATTENTION ●

Make sure to tighten the collar of the connector by hand. If it is tightened using a tool, the connector may become damaged. If the installation environment does not allow proper tightening by hand and there is a possibility that it may come loose, tighten by an additional 1/4 turn using a plier after tightening by hand.

●

Do not apply excessive force on the screws of the connector. The connector may become damaged.

●

Do not cut the FL sensor / FW extension cables shorter. It may cause problems, such as not being able to perform up to specifications.

Point

●

When connecting the connectors, make sure that the cable is not twisted. If there is twisting stress on the cable, it may slowly loosen the connection. If a twisting force is applied to the direction where the collar will be loosened, twist the extension cable slightly to the opposite direction of the collar tightening direction before connecting, then connect the connector and tighten the collar.

●

We recommend that excessive extension cables be stored in the cable storage box. If it is unavoidable to store inside the driver housing, do not force excessive cables into the housing.

Connections are performed in the following order. 1. FW extension cable connection (When using the FW extension cable) 2. FL sensor connection 3. Monitor (VM monitor) connection 4. Confirmation after connection completion 5. Confirmation of set gap voltage


27


FW extension cable connection (When using the FW extension cable) When using the FW extension cable, connect the FL sensor and FW extension cable as shown below. Point

The connection area of the connector must not be used in a condition where it is exposed to water or oil. If water or oil enters the connector, the cable capacity will increase, and will cause a loss in sensitivity.

1

Confirm that there are no foreign objects in the FL sensor and FW extension cable connectors. Foreign objects in the connector will cause faulty connections or faulty characteristics.

2

Insert the extension cable through the provided insulation sleeve (clear heat shrink tube).

3

Connect the FL sensor connector and FW extension cable connectors, and tighten the collar by hand.

4

Cover the insulation sleeve over the

3.4.2

FL sensor connection Connect the FL sensor as follows. Connection is performed in the same manner when using an FW extension cable.

1

Confirm that there are no foreign objects in the FL sensor (or FW extension cable), and in the FK driver sensor input connector. Foreign objects in the connector will cause faulty connections or faulty characteristics.

2

Connect the FL sensor (or FW extension cable) connector and the sensor input connector, and tighten the collar by hand.

3.4.3

Monitor (VM monitor) connection Connect the monitor as follows.

ATTENTION

When using a cable that has been subject to a megger test, make sure to short the cable to ground before connecting, to discharge any electric charge in the cable. Connecting the cable in a charged condition to the unit or the monitor may damage the unit.

Point

●

We recommend using cables described in “2.3.6 Recommended specifications for the monitor cable” (

Page 11) between the unit and



monitor. Because a small signal is being transmitted, a cable that is not recommended may be subject to interference from external noise, and the measurement may become affected. ●

We recommend using a round crimped terminal (JIS C 2805 equivalent) for the monitor side cable terminal, as it provides a good contact and there is little deterioration from aging.

●

We recommend that the length of the non-shielded area be kept under 100mm.

●

For the terminal block arrangement of the monitor, refer to the instruction manual for the monitor.

1

Remove the insulation so that there is 9mm of exposed wire, and twist the wire.


29


2

Refer to the following drawing, and connect the signal transmission cable to the FK driver and monitor. Connect to the terminal block of the FK driver according to the following procedures. 1. Use a flat tip screwdriver to push down the operation lever of the terminal block (the orange area). (Recommended flat tip screw driver size: W2.5mm × T0.4mm)

2. Insert the signal transmission cable (the 9mm of exposed wire) all the way into the cable insert port of the terminal block, until it hits the back. 3. Pull out the flat tip screwdriver from the operation lever. The signal transmission cable is locked and the connection is complete. Point

The terminal block is affixed by the 2 screws on the ends of the terminal block. If these screws are loosened for installation or inspection work, make sure to affix the terminal block after work is complete by tightening the screws. Refer to “6. INFORMATION ABOUT INTRINSICALLY SAFE APPLICATION”in case of the intrinsically safe spesification. ( Page 45)
