Hot Wire Semiconductor Sensor

Detects resistance changes  across the edges of platinum wire as a result of variations in thermal and electrical conductivity due to absorption of gas on the surface of a semiconductor.

Features

• Sensitive and large variation in output at low gas concentration.
• Less initial stabilization time, more compact, more energy saving as compared with a semiconductor sensor.
• Long service life, high stability, and high durability.
• Selective sensitivity to gasesH2, CH4, C2H5OH.
