The Geopal GP-SA stand-alone detector represents one of the lines in a new generation of gas detectors featuring an integrated microprocessor. The detector continuously monitors the gas concentration, whether it is in the 0-100% LEL range (lower explosion level) or the 0-40,000 ppm range, in connection with e.g. refrigerants.In the Geopal GP-SA detector the sensor signal is converted to a linear output signal of 4-20 mA or 0-5/ 10 V, and the detector is equipped with alarm relays for both low alarm, high alarm and system fault. Long-life sensorThe semiconductor sensor will typically last much longer than an electrochemical or a catalytic sensor. Another advantage is that it costs less to replace. Simple installationFor the external wiring of the detector a three-conductor cable is normally all you need. Depending on how many relay functions are required, the number of conductors would be increased accordingly. The detector is also available with a six-pole DIN plug, an option which is usually preferred if you wish to be able to quickly replace the detector. For that purpose we can also offer a mounting device that enables you to replace the detector in matter of a few minutes.
