THERMOPILE
Thermopile Sensor OTP-N538U
Revision Date: 2018/01/08 (Rev.05)
OTP- N538U
The OTP-N538U is a thermopile sensor in classic TO-46 housing. The sensor is composed of 116 elements of thermocouple in series on a floating micro-membrane having an active area of diameter 545 μm. The thermopile sensor provides nearly Johnson-noise-limited performance, which can be calculated by its ohmic series resistance. A thermistor element, with a lead connected to ground, is also provided inside the TO package for ambient temperature reference.
TO-46 metal housing with IR absorber coating inside Thermistor temperature reference included Low temperature coefficient of sensitivity Ideally suited for ear thermometers, miniature pyrometer.
