Note 1. Optional thermometer can be connected to TT2000C and TT2000M for auto temperature adjustment
Input temperature range is from -40?C to 200?C. Measurement over 60?C requires a sensor specially
designed for high temperature.
2. RS232C connector is available only with TT2000C and TT2000M.
3. Composite output, alarm output and encoder input are available only when using a multi connector box
(TT2000M) or optional built-in battery case.
4. DC12V can be used only when using the optional portable battery or the built-in battery case.
5. Certi?cate of calibration is available on request, charged option.

Axial Tension Calibrator Ultrasonic Sensor
Model Part # Name Applicable Bolts
AFC-20G 607 5C6.4N More than M8, L1<approx.50cm
608 5C12.7N More than M14, L1<approx.2m
Note 1. L1 is standard bolt length with material in SCM, S-C, SS for ultrasonic wave reflection measurement n=1.
2. Ultrasonic wave sensor is consisting of 3 parts, Sensor, Magnet Holder and Bolt Holder.
3. Standard 5C6.4N does not include bolt holder.
4. 5C6.4N=[5: Frequency (MHZ)]
[C: Oscillator Material (C: piezoelectric ceramics)]
[6.4: Oscillator Diameter, mm]
[N: Perpendicular (Normal)]
Force Measurement
Features of ultrasonic wave sensor
1. The magnetic holder provides stabilized force through the sensor, which provides high repeatability Instrument
measurement.
2. The bolt holder gives same position of the sensor to support more accurate measurement.
