Description
2 channel premium thermopile sensor for the measurement of hydrocarbons (HC). IR filters with a CWL of 3400 ± 20 nm and a HBW of 140 ± 20 nm and a particularly high detectivity of up to 6,27*108 cm√Hz/W as well as a very high sensitivity of up to 171 V/W guarantee precise and long-term stable measurement results.
The Thermopile is suitable for demanding industrial applications such as industrial gas measurement, coolant monitoring or process analysis.
Two detector chips with 200 bismuth antimony/antimony thermopiles each form the core for this 2 channel thermopile. The signal quality is comparable to that of pyroelectric detectors. The integrated thermistor for reference temperature determination, an interference absorber and an additional reference channel (CWL: 3910 ± 28, HBW: 70 ± 10 nm) optimize the measurement results of the dual IR detector.
For this product, customer-specific adaptations are possible as well as agreements on graduated prices.
