Thermopile detector

T11722-01

For CO2 concentration measurement, High sensitivity

The T11722-01 is a dual-element type thermopile detector designed to detect CO2 concentration with high accuracy. It

consists of a high sensitivity dual-element thermopile detector and two band-pass filters for sensing two wavelengths

(reference: 3.9 μm, CO2: 4.3 μm) simultaneously.

Since the thermopile output signal is very low in the order of microvolts, use an amplifier with a low offset

voltage. (Example: LTC1050)

Precautions

The band-pass filters used in this product have a secondary transmission at wavelengths longer than 10 μm. If the secondary

transmission affects measurements, install a sapphire glass, etc. in front of the light input window to block long wavelength light.
