The rugged, reliable AST-IRT refrigerant transmitter is available with infrared (IR) sensors to detect a wide range of refrigerant gases.
The IR sensor is a reliable method of monitoring for refrigerant gas leaks in environments that have air quality problems. The IR sensor will eliminate many false alarms in environments that contain gasoline, diesel and propane exhaust and fumes from solvents, paints, cleansers, and others.
AST-IRT transmitter output a linear 4 - 20 mA signals that can be sent to a controller or building automation system.
The standard enclosure is a rugged aluminum and an optional watertight ABS fiberglass enclosure for wash down protection and stainless steel enclosure for special applications are available.
Calibration is recommended at 6 month intervals and is a simple one button zero adjustment with no calibration gas required.
