C18-24 Hydrogen Sulfide gas generator

The Auto-test option verifies the serviceability of the transmitter on a prescribed schedule by exposing the sensor to a small amount of gas, and verifying a minimum response. Three attempts per test are made, and if the sensor does not respond on the third attempt, a fault alarm is triggered (may be optionally disabled).

The test is performed at a specific time of day, and may be scheduled to repeat every 1 to 14 days. The date and time of the next test is available for editing, and the test may be triggered manually at any time, without affecting the preset schedule.

The Auto-Test Generator can be easily added to the standard Integral Sensor Holder.

The Auto-test option requires an E18 gas generator, which must be compatible with the installed sensor’s gas type, and full-scale range. Table below lists gas compatible generators and sensors.
