Compact infrared CO2 sensor safety switch (NDIR CO2 sensor safety switch)
The infrared CO2 sensor safety switch (NDIR CO2 sensor safety switch) S8-4B, during normal operation, tests the CO2 gas concentration in the environment every 30 seconds. When the CO2 concentration exceeds 8000 ppm, the sensor emits an alarm signal. If any malfunction is detected, the error detection path emits an alarm signal. The alarm filter protects the sensor from false alarms caused by intermittent interference.
