MSR Germany Ammonia NH3 Transmitter – ADT23 1125 Monitoring SensorBy ALVI
ALVI Automation – India (http://www.alviautomation.com) in association with Gas Alarm Systems – Australia (http://www.gasalarm.co.au) offer MSR Germany Ammonia NH3 Transmitter – ADT23 1125 Monitoring Sensor.
NH3 transmitter including digital measurement value processing and temperature compensation for the continuous monitoring of the ambient air to detect ammonia concentrations. A comfortable calibration routine with selective access release is integrated in the transmitter. The ADT-23 possesses a standard analog output, (0) 4–20 mA or (0) 2-10 V DC, and an RS-485 interface. 2 relays with adjustable switching thresholds are available as an option.
For detecting leakages in refrigeration plants with ammonia as refrigerant, and also within a wide range of commercial and industrial applications. Due to the standard analog signal and the RS-485 serial interface the NH3 transmitter is compatible to the PolyGard gas controller series MGC and DGC by MSR-E as well as to any other controllers or automation systems.
