Thermopile detector

T11361-01

High-sensitivity, for gas density measurement, built-in thermistor

 

The T11361-01 is a thermopile detector equipped with an internal thermistor for compensating for outuput variations caused by changes in the ambient temperature. It uses a TO-18 package with a window having high transmittance in the 3 to 5 μm spectral band. By attaching an external band-pass filter to the thermopile detector, it can be applied to various types of gas density measurements.
