Designed to detect methane, CO, LPG or petrol vapours, this gas concentration transmitter has a 4-20mA current output. Its metal housing with Ex d protection contains an electronic circuit and sensor suitably protected by a sintered filter. The device can be installed in ATEX Zone 1.
The concentration gas transmitters Series SX-X consist of the following components:
- the gas sensor.
- the electronic conversion circuit.
- the terminals for the electrical connection of power supply and signal output.
- the metal housing and relevant sensor holder with sintered filter that ensure the ATEX protection mode for the entire device.
The gas sensors that fit inside the ATEX protective housing can be of various types, either for gas fuel or for toxic gases as well as for Oxygen.
The mounted terminals provide by standard both an analog current output (4..20mA) and a digital Modbus® output.
All models work with the following control units:
- RY M02M0
- RY M02M1
- RY M02M2
- RY K01M
- RX A01M
This transmitter must be used to measure the gas for which it has been calibrated (see the marking on the device for the kind and range of the gas).
Long term stability: In normal functioning conditions and without potential toxic substances in the environment, which may alter the operation, the catalytic sensor has a good long term stability of 5 years starting from the installation and when put in operation for the first time.
