Consilium ST350EX-SCF R134a Gas Detector (1227050)
ST350EX-SCF semiconductor MOS gas detector for R134a detection over 0-1000 ppm. The manufacturer describes the ST350EX as an all-round gas detector and states that the SCF sensor is suitable for detecting synthetic refrigerants including HFO and HFC types. Manufacturer-listed system references: CGD50, CGD500 TOUCH. Manufacturer wiring diagrams show 3-wire 4-20 mA transmitter operation, Modbus RTU slave operation, and combined 3-wire 4-20 mA plus Modbus operation; they do not establish site-specific installation requirements.
