Bourdon tube pressure gauge with switch contacts
Description
Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, this switchGAUGE finds its use.
Switch contacts (electrical switch contacts) make or break an electric control circuit dependent upon the pointer position of the indicating measuring instrument. 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.
For further approvals, see page 11
Model PGS23.063 with switch contact model 830 E.21
Switch contacts consisting of 2 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 all requirements of the relevant international standards and regulations for the on-site indication of the working pressure of pressure vessels.
As switch contacts, magnetic snap-action contacts, reed switches, inductive contacts and electronic contacts are available. Inductive contacts can be used in hazardous areas. For triggering programmable logic controllers (PLC), electronic contacts and reed switches can be used.
Special features
- Up to 2 switch contacts per instrument
- Instruments with inductive contacts for use in hazardous areas
- Instruments with contacts for PLC applications
- Safety version with solid baffle wall (Solidfront)
