Thermopile Sensors are used for measuring non-contact surface temperatures. The ZTP-101T type is made up of thermo-elements, a flat Infrared (IR) filter, a thermistor for temperature correction, and a hermetically sealed small-size package. There are also other filters available to optimize performance in specific applications.
Applications
- Patient observation
- Tympanic and ear thermometers
- HVAC
- Appliances
- Occupancy detection
Features
- Fast response time
- High sensitivity
- Included ambient temperature (thermistor) sensor for compensation
- Low cost
- Non-contact measurement
- Small-size sensor package
