Thermometrics Thermopile Sensors are used for non-contact surface temperature measurement. The ZTP -101T model consists of thermo-elements, flat Infrared (IR) filter, a thermistor for temperature compensation and a hermetically-sealed small-size package. There is also a variety of filters available to maximize performance in specific applications.
Features
- Non-contact measurement
- Wider surface area measurement
- Small-size sensor package
- Included ambient temperature (thermistor) sensor for compensation
- High sensitivity
- Fast response time
- Low cost
