Thermometrics Infrared (IR) Sensors
ZTP-315
Thermometrics ZTP-315 Infrared (IR) Sensors consist of thermo-elements, flat infrared filter and a thermistor for temperature compensation, all in a hermetically-sealed TO-46 (18) package. Thermopile IR Sensors are used for non-contact, or infrared, surface temperature measuring. There are also a variety of filters available to help maximize performance in specific applications.
- HVAC
- Occupancy detection
- Automotive
- 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
