DTT-A-100 DISPLACEMENT TRANSDUCER INSTRUCTION MANUAL
Thank you for purchasing the KYOWA product. Before using it, read this
instruction manual carefully. Also, keep the manual within easy reach so that
you can refer to whenever necessary.
Specifications and dimensions described in this manual could be changed
without notice. Please visit our website for the latest version.
1. Calling the operator’s attention
The following cautionary symbols and headlines are used to invite the
operator’s attention. Be sure to observe the accompanying precautions in
order to safeguard the operator and preserve the performance of the
instrument.
Warning Improper handling can cause serious injury to the
operator.
Caution Cautions are given to invite the operator’s attention, in
order to avoid instrument failure or mal-function.
2. Important notice
Unless specified, the transducer must not be used under hydrogen
environment.
3. Safety Precautions
Warning
●
As you push the rod inward, the rod returns to its initial position by
reaction force. Handle the product with care to avoid eye poking.
4. Handling Precautions
Caution
●
Do not apply excessive axial or bending force on the rod.
●
Do not rotate the rod. (For replacing accessories, see 9.)
●
Do not disassemble the product.
●
Do not use the product under water and dusty environment.
●
Use the product under environment without vibration.
●
Pay similar attentions toward the product as one gives to regular dial
gages.
●
Always keep the rod clean.
●
Make sure that the bending radius of cable is longer than 10 times of a
diameter of the cable.
5. Installation
5.1 Fix the DTT-A to the fixed point by using the accessory 2 mounting bands
(FXBP-100A), 2 wing bolts (M4×12) and M6 bolt.
The M6 bolt is not included.
5.2 Make sure the displacement of 0.5 mm or more is applied to the DTT-A.
5.3 The DTT-A and dial gage measures data by contacting the probe onto
the measuring point. However, some DTT-A rods may not track dynamic
data correctly. Make sure the rods works correctly.
5.4 To fix the rod to the measuring point, remove the prove and fix the rod to
the measuring point by using a screw (M2.5).
5.5 To measure displacement by pulling the rod, connect the accessory
adapter into the rod end.
6. Connection
6.1 Connect the DTT-A to a measuring instrument.
6.2 Connect the connector plug as follows.
(Shield is not connected to the chassis.)
6.3 After the power ON, always preheat the product for approximately 5 to 10
minutes.
Caution
When using the UCAM series, since the output terminals of the DTT-A
do not match with that of the UCAM series, you are not able to connect
the connector plug. In this case, connect the conversion cable (U-17,
bared at the tip, optional). Connect the green wire (output +) into the B
terminal of the UCAM series. Since the white wire outputs no data,
connect the shield wire and white wire. Connect the white wire (no
output) into the E terminal of the UCAM series. Make sure the measuring
mode of the UCAM series is “Potentiometer-type displacement
transducer.”
7. Conversion
7.1 Use the calibration constant described on the Test Data Sheet to convert
a measured value into a displacement value.
7.2 You are able to calculate a displacement value by using the measured
value and calibration constant described on the Test Data Sheet. The Test
Data Sheet has displacement, corresponding to 1 (V/V). You are able to
calculate a displacement value by them.
Displacement (mm) ＝Output voltage (V) / Bridge excitation (V) ×

8. Maintenance and inspection
8.1 Avoid water, dust and oil from the product.
8.2 Recommend calibrate the product once a year or so. (Contact your
KYOWA representative.)
8.3 If an abnormal initial value or reading appears, measure the resistance
(between red and black) and insulation resistance (100 MΩor higher).
If abnormal resistance is found, the DTT-A may be failure.
Contact KYOWA or our representatives.
Caution
●
To measure insulation resistance, apply a voltage lower than 50V to the
insulation resistance tester.
9. Standard Accessories
Mounting band: FXBP-100A
Adapter
Ballpoint probe: X-1-DT
10. Special Accessories (Optional)
Caution
Before installing probes and screws, be sure to insert the accessory pin
(φ2×20) into the rod hole. While installing probes and screws, hold the
pin tightly instead of holding the product. Do not apply excessive axial or
bending force on the rod. Or, the product may be damaged.
(Supplement)
Do not rotate the probe by holding the product. Do not rotate the rod.
Or, the product may be damaged.
10.1 To install the replacement probe (optional), use the spring washer and
plain washer.
10.2 After installing the replacement probe or extension rod (optional), some
rods may not work correctly depending on the DTT-A direction. Before
measuring data, make sure the rods works correctly.
To install the replacement probe
To install the extension rod
Flat probe: XS-2-DT
Spheric probe: XS-6-DT
[NOTE]
When the object to be measured is sphere, use the XS-5-DT and XS-2-DT.
