Description
The Texas Electronics, Inc. Model TT-103R-W Temperature Sensor utilizes a highly sensitive linear thermistor-resistor network as the sensing element. Sensors feature direct interchangeability with one another without system recalibration. Temperature variations create a resistance bridge imbalance, the subsequent output signal varying linearly with temperature.
The TT-103R-W has the same characteristics as the TT-101QR. The sensor is housed in a brass thermowell with a waterproof connector. The thermowell can be screwed into a ¼" - 14 NPT pipe thread for monitoring fluids or pipes or can be mounted to a surface by the bracket provided. It can also be directly buried in soil or pavement.
Features & Benefits
- Available in four different temperature ranges
- Signal Conditioner output can be interfaced with indicators or dataloggers
- Brass thermowell with waterproof connector provides ease in installation and maintenance
- Sensing element utilizes a highly sensitive linear thermistor-resistor network
- Optional Yellow Springs sensing element available
- Over 25 years in production
- Rugged construction allows varied applications in fluid or solid mediums
Installation & Maintenance
Installation:
Brass thermowell housing with waterproof connector can be screwed into a ¼" NPT pipe thread for monitoring fluid in pipes, or mounted to a surface by provided bracket. It can also be directly buried in soil or pavement. Probe comes with a 6 ft. (1.82 meter) or a 60 ft. (18.28 meter) sensor cable.
Calibration / Cleaning Frequency:
The temperature system should not require calibration, however, the system may be checked for accuracy each six months, if desired. In the event that it is required, field calibration (zeroing and spanning) can be readily accomplished by substituting fixed standard resistor values for the sensor output.
No cleaning program should be required with normal use.
