4 digit LCD display

Description

Digital pressure gauges provide a digital local indication independent from mains supply.

Their accuracy, reliability and resistance to mechanical load make them suitable for pressure measuring tasks in various applications.

To ensure an easy readout in any installation position the front cover may be rotated up to 350°.

Additionally the display case may be rotated axial-wise by untightening the counter nut at the pressure connection.

The measuring ranges, graded in accordance with EN range from 1 bar up to 400 bar.

The programming of the parameters is done by means of the front keys.

The integrated battery guarantees an operation independent from mains supply.

Optionally a peak value memory, an analoge output or a limit contact can be provided.

The digital pressure gauge meets the electronic magnetic compatibility (EMC) requirements to EN 61 326.
