Geopal GP-SA

The Geopal GP-SA stand-alone detector is designed for refrigeration, industry and marine.

The GP-SA is an ideal gas leak detector for refrigeration industry applications with selectable sensors depending on target gas.

The GP-SA detector uses an integrated microprocessor for continuously monitoring the gas concentration, whether it is in the 0- 100% LEL range (lower explosion level) or the 0-40,000 ppm range, for e.g. refrigerants. The signals of the Geopal GP-SA detector are converted to a linear output signal of 4-20mA or 0-5/10V.

The detector is equipped with alarm relays for low alarm, high alarm and system fault.

As an option the detector is available for pipe mounting, duct mounting and with a DIN plug for easy mounting / dismounting.

Easy to calibrate

The servicing of Geopal GP-SA requires no special tools or equipment, only a test gas with the given gas concentration. The actual calibration can be carried out by one person in less than 10 minutes, using a simple push-button system with associated light indicators.

Simple installation

For 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.

Linear output

Based on a mathematic analysis of the characteristic formed by the semiconductor sensor, the detector generates a model, which results in an analogue output that will be linear in the entire detection range.
