Description
The model PGS21 switchGAUGE is a combination of a Bourdon tube pressure gauge and either one or two switch contacts. It offers the usual analogue indication, 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 to 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.
