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

  • Fast response time
  • High accuracy
  • Wide temperature range
  • Maintenance-free
  • Compliant with IEC / UL 60335-2-40
  • Factory calibrated
  • Long term stability
  • Long lifetime
  • Immune to poisoning
  • Based on LED light source

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.
