3.1.6. Resistor Type Transducer Connection
The CT-7500 S2 provides one channel for resistor type transducers. The transducer resistance
input can range from 200 Ohms to 10K Ohms. The CT-7500 S2 supplies a 5 Vdc reference
voltage to power the resistor type transducer. The sense voltage is translated into a travel
distance based on the transducer calibration parameters. The user is required to setup the
resistor transducer before performing a test. Up to nine transducer setups can be stored in the
CT-7500 S2’s internal memory. Once a transducer setup is stored, it can be recalled quickly
before running a test. A typical resistor type transducer connection is shown in Figure 10.
NOTES
• When a resistor type transducer is used, the test results are shown as travel
transducer channel 1 (see Figure 16).
• A 15-foot transducer cable with 3 quick disconnect clips is provided with each CT-
7500 S2. The 3 clips are labeled “+5V”, “Signal”, and “GND”.
• See section 3.1.19 for resistor type transducer calibration information.
