Bourdon tube pressure gauge with switch contacts
Models PGS23.1x0, stainless steel version
Bourdon tube pressure gauge model PGS23.100 with
switch contact model 831.1
Description
Wherever the process pressure has to be indicated locally,and, at the same time, circuits are to be made or broken, the model PGS23.1x0 switchGAUGE can be used.
Switch contacts （electrical alarm contacts） make or break an electric control circuit dependent upon the position of the instrument pointer. The switch contacts are adjustable over the full extent of the scale range （see DIN 16085）, and are mounted predominantly below the dial, though also partly on top of the dial. The instrument pointer （actual value pointer） moves freely across the entire scale range, independent of the setting.
The set pointer can be adjusted using a removable adjustment key in the window.
Applications
Control and regulation of industrial processes
Monitoring of plants and switching of electric circuits
For gaseous and liquid aggressive media that are not highly viscous or crystallising, also in aggressive ambience
Process industry: Chemical, petrochemical, power plants,mining, on- and offshore, environmental technology, machine building and general plant construction
Special features
High reliability and long service life
Up to 4 switch contacts per instrument
Also available with liquid-filled case for high dynamic pressure loads or vibrations
Gauges with inductive contacts for use in hazardous areas with ATEX approval
Gauges with electronic contact for PLC applications
Gauges in safety version S3 （k）
Switch contacts consisting of several contacts can also be set to a single set point. Contact actuation is made when the actual value pointer travels beyond or below the desired set point.
The pressure gauge is manufactured in accordance with DIN 16085 and fulfils all requirements of the relevant standards （EN 837-1） and regulations for the on-site display of the working pressure of pressure vessels.
As switch contacts magnetic snap-action contacts, reed switches, inductive contacts - for requirements to ATEX - or electronic contacts for triggering a PLC are available.
For further information on the different switch contacts please see data sheet AC 08.01.
