4. Design and function

Description
Bourdon tube measuring elements are widely used in technical pressure
measurement due to their robustness and ease-of-use. Under the infuence
of pressure, these measuring elements deform within their elastic limits.
This motion is converted, via a mechanical movement (toothed gear), into
a rotational motion. To this, an electrical limit switch is connected - the
magnetic snap-action contact. The contact closes or opens the connected
electrical circuits when the settable limit values are exceeded.

Electrical connection

The electrical connection must only be made by qualifed skilled
■
personnel
Connection of the switches via cable or via screw terminals in the
■
terminal box (L-connector)
The terminal assignment is stated on the product label of the pressure
■
gauge
The gauges must be connected to the equipotential bonding of the plant
■
