Ear Thermometer Non-contact Measurement Metal Housing Thermometrics Infrared Detectors Thermopile IR Sensor ZTP-148SR
Ear Thermometer Non-contact Measurement Metal Housing Thermometrics Infrared Detectors Thermopile IR Sensor ZTP-148SR
Description
ZTP Thermopile Infared (IR) Sensors are industry-leading higher sensitivity level sensors. These devices respond to a broad infrared spectrum, offer an inherently stable response to DC radiation, and do not require source of bias voltage or current. Consisting of thermo-elements, flat IR filter, and a thermistor for temperature compensation in a hermetically-sealed TO package, the series has a variety of filters available to maximize performance in specific applications.The ZTP IR Thermopile devices are used to provide non-contact temperature measurement in thermometry, microwave ovens, induction heater cookers, air conditioners, occupancy detection, lighting, underfloor heating control, and HVAC / automotive applications.
We are not limited to off-the-shelf, standard designs and cater to user customization for the most demanding infrared sensing applications,as well as PCB .
