CO2 detection for Cold Storage
CO2 leaks in cold storage rooms can quickly become dangerous because CO2 refrigeration systems operate at high pressures. In the case of subcritical and transcritical systems, these are often above 100 bar. The IR22 F transmitter reliably monitors the CO2 concentration under the toughest of conditions. whilst providing additional safety functions.
Robust and Durable
The rugged IP65 transmitter IR22 F measures Carbon Dioxide (CO2) from -40 °C to +60 °C. Two switching outputs enable connectivity to additional safety devices, such as audible and visual alarms or self-contained alarm push buttons for each detection point. Tri-Colour LED status (green, yellow and red) provides instant operating status of the transmitter.
Digital, Analogue or ACDC
The IR22 F is available with digital RS-485 interface and Modbus protocol or as analogue 4-20 mA. It is also ACDC-capable (Analogue Carrier for Digital Communication) which allows additional data to be transmitted digitally over the 4-20 mA cabling. Dependant on transmitter quantity and the connected alarm devices, bus cable lengths of up to 1200m are possible.
Manual Alarm/Alarm acknowledgement
The digital input can be used to connect a manual push button for instant alarm activation/alarm acknowledgement.
