Description
The model PGS21 switchGAUGE® is a combination of a Bourdon tube pressure gauge and a pressure switch. It offers the usual analogue display, which can be read on-site irrespective of the power supply, and in addition the possibility to switch a potential-free electrical signal. One or two switch points are factory-set to customer requirements, fixed between 10 % and 90 % of the scale range, and indicated on the dial by red mark pointers. Depending on the pointer position, the circuit will be opened or closed. Thus the switchGAUGE® can be used actively for process monitoring, for example to monitor the level of a gas cylinder or a hydraulic circuit. The switchGAUGE® is available in scale ranges from 0 ... 2.5 to 0 ... 400 bar [0 ... 60 bis 0 ... 6,000 psi] with an accuracy class of 2.5 and a 1 m round cable for the electrical connection. There are further versions available, e.g. with higher accuracy class, a different cable length or with plug connection. Thus, the instrument can be adapted to customer-specific requirements for each application. The instrument has been designed in accordance with EN 837-1 and fulfils all the requirements within it. Furthermore it features increased ingress protection of IP65 and can therefore be offered with optional liquid filling to increase its vibration resistance.
