TCAII-OO(]Operation Manual of TML Displacement Thansducers

This operation manual applies to the following products, but a product with special specificationspartly out of this manual.

CDP Series displacement transducersPlease be sure to read the manual before use and retain it together with test data.

1. DIMENSIONS

2. INSTALIATION

O Drill a M6 thread hole in the surface of an object on which the CDP unit is mounted. Using amagnet stand, e.g. type MB-8, makes optional installation possible but you must take intoconsideration some effect on the measuring accuracy due to deformation of the probe fixture or rodof the MB-B stand.

@ Fit the supplied fixing holder to the body of the unit (use two holders for CDP-50 and CDP-100)and tighten thc supplied screw. Pay attention not to excessively tighten it. Recommended tighteningtorque is 0.7N ' m (7kgf ' cm) or less. Refer to the graduation on the shaft or the measurement valueof a measuring instrument for positioning.

@ Make sure that the direction of displacement to be measured coincides with the axial center of theCDP unit.

@ As the shaft docs not move in excess of the rated capacity, takc care that it should notexcessively pressed down. When exchanging the contact tip, take care of looseness of thcbecause the shaft rotates.

@ Do not fix the shaft direct to the test object. Do not release quickly from the state of the shaftbeingirlly pressed down; otherwise the CDP unit may be damaged by spring reaction.

MEASUREMENT

The CDP unit is calibrated with a constant voltage excitation type strain meter using the suppliedcable. The rated output and scnsitivity shown on thc test data are found with an instrumcnt gaugefactor of 2.00. ( In case of using TML data logger, its coefficient should be set to 1.000. )

One end of the supplied cable does not usually have a connector plug. the cable is connected toa strain meter or its switching box by screwing or soldering. In case of using NDIS 7-pin plugrefer to the following connection layout.

@Comector pin laJDut

' N.B.The shield wire of the cable is not connected to the body of the CDP unit.

@ S"t necessary measuring'parameters to a strain meter, recorder, computor, etc. ( for strain meter,for instance, initial balancing, sensitivity adjustment, setting of unit, coefficient and measure modeinitial value measurement, ctc.)

@ In ordinary measutement, it is recommended that a strain meter is previously set to direct measuremode in mm. In case of reading strain, displaccment is calculated using the following equation:

X Calibration coefficientI mm,/lxto-61

The calibration cocfEcient is a value obtained by dividing the rated capacity (-m) by the ratedoutput (x lQ't.

@ When the shaft is pressed down, thc measured value changes in negative polarity. 7*roadjustment of this unit is made at thc state of the shaft being pressed approximately halfway.

@ In ca!" the length.of cable is extended, you must correct the lowering of sensitivity using thefollowing equation: '(N.B. only when bridge excitation is constant voltagi)

4. CAUTIONS

O Do not apply strong vibration or shock to the CDP unit. If the bearing part is used for fixing,movement of the shaft may be prevented.

@ Do not grease the shaft and bearing. Take care that the shaft is not hurt, bent excessively presseddown; otherwise, operation failure will be caused. Ifthe shaft is quickly released from the state ofthe shaft being pressed down, the unit may be damaged due to reaction

@ Do not forcedly bend the cable near the cable intake. Do not place an object on the cable, norpull nor flaw the cable.

@ The CDP unit has no hermetically sealed construction (bearing, cable intake section, etc.),so takecare that water or oil does not permeate from the end of cable.

@ Continuous use with a bridge excitation voltage over recommendation may produce drift and as aresult, performance will become out of specifications.

Rcommndcd brilgc c)ail8tiotr Albwablc bridgc ercitationAll CDP- units Less than 2V 10v

@ In case of using other instrument than strain meter, make sure that excitation voltage is very stable@ Do not apply voltage larger than the allowable bridge excitation.@ Do not disassemble nor modify the unit.

5. ClIECKand STORAGE@ Make sure that the shaft moves smoothly.

Make sure that the value [X 10'6] measured in DIRECT mode of the strain metor with the shaftbeing pressed halfiray is not excessively large.

@ Using an insulation resistance tester with an excitation voltage of DC 50V or less, measureinsulation resistance [M0] betrveen input/output wires of the cable (4 wires of red, green, blackand white ) and the CDP unit body to confirm that the insulatiou resistance is kept at about1000MfJ or more.

@ Using a digital voltmeter or tester, measure terminal resistance [ 0 ] between output wfues (red andblack) and input wires (green and white). Make sure that the measured value is not largelydifferent from the value shown on the test data sheet.

@ For storage, avoid a high or low temperature, high humid place, dust, water drop, vibration, shock,etc. Handle the supplied cable as well but with a cable cap put.
