R99-2012SC Refrigerant Gas Advanced Semi-Conductor Sensor

Refrigerant gas transmitter with semi-conductor sensor for monitoring leakages of cooling agents like HFC (hydrofluorocarbon) or HCFC (hydrochlorofluorocarbon).

The semi-conductor typical, non-linear signal is translated into a linear, temperature-compensated output signal. A comfortable calibration routine with selective access release is integrated in the transmitter. The ADT-43 possesses a standard analogue 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.

Features:

• Non-intrusive calibration
• Digital measurement value processing incl. temperature compensation
• Linear output signal
• Continuous monitoring
• Low zero point drift
• Good stability to poisoning
• Semi-conductor sensor with long life-time
• Modular plug-in technology
• Comfortable calibration with selective access release
• (0) 4 – 20 mA / (0) 2 – 10V analog signal output, selectable
• Serial interface RS-485
• IP65 protected
• 4 – 20 mA analog input for external AT transmitter (optional)
• Approved according to EN 61010-1; ANSI/UL 61010 1; CAN/CSAC22.2 No. 61010-1
• Relay output
