SX-X gas concentration transmitters have an ATEX-certified metal enclosure with Ex d protection for Zone 1. Suitable for methane, CO, LPG or petrol vapours. The series consists of the following components:
- Gas sensor
- Electronic conversion circuit
- Terminals for electrical connection of power supply and signal output
- Metal housing and sensor holder with a sintered filter that provide the ATEX protection mode for the entire device
The gas sensors inside the ATEX protective housing can be of various types for combustible gases, toxic gases or oxygen. The terminals provide both an analog current output (4…20 mA) and a digital Modbus® output.
Compatible Control Units
- RYM02M0
- RYM02M1

- RXA01M
Use: The transmitter must be used only to measure the gas for which it has been calibrated; see the device marking for the gas type and measuring range.
Long-term stability: Under normal operating conditions and in the absence of potential toxic substances that could alter operation, the catalytic sensor provides good long-term stability for five years from installation and initial operation.
