RDS R290

The Senseair Refrigerant Detection System R290 is a leak detection sensor module for HVAC applications using the low GWP refrigerant R290.

Defining attributes

  • Immunity to poisoning
  • Complies with: UL 60335-2-40 ed.4 IEC 60335-2-40 ed.7 IEC 60079-29-1
  • High accuracy
  • High resolution
  • Fast response time
  • -40 – 70 °C operating temperature
  • Maintenance free
  • Optional voltage variations (24V, 12V, 5V)

A protective housing, with a high-quality gas diffusion vent, protects the sensor element from dust and condense water droplets. Thanks to the built-in heating element, the Senseair RDS can operate in cold environments.

Using Modbus protocol, the measured data can digitally be transmitted to the control system.

A digital output signal is activated whenever the measured gas concentration reaches a configurable threshold. The output can alternatively be configured as a digital PWM signal or an analogue linear output reflecting the measured gas concentration.
