1. Safety instructions
The appropriate national safety regulations (e.g. VDE 0100 / EN 60 079-14 /
EN 837-2) must be observed when installing, putting into operation and
running these instruments.
T Do not work on gauge while under voltage
T Serious injuries and/or damage can occur should the appropriate regulations not be
observed
T Only appropriately qualified persons should work on these instruments
2. Description
T Nominal size 63 mm
T The pressure gauges measure the pressure by means of resilient bourdon tube measuring
elements
T The measuring features are in accordance with the standards EN 837-1
T In addition the case and bezel ring as well as the pressurised components of models
232.3X also meet the requirements of this standard on safety pattern pressure gauges
with solid baffle wall (code S3).
The built-in electrical alarm contacts are non-contact slot-type inductive proximity sensors,
which are supplied from control units with circuits that are certified to be intrinsically safe.
When the adjustable set points are reached, their output circuits will be opened or closed.
The connection values of the switches are in accordance with EN 60 947-5-6 ("NAMUR").
3. Technical data and intended use
Working pressure
Steady:
full scale value
Fluctuating: 0.9 × full scale value
Short time: 1.1 × full scale value
Pressure connection
T According to the general technical regulations for pressure gauges, respectively
(e.g. EN 837-2 "Selection and installation recommendations for pressure gauges").
When screw-fitting the gauges the force required for sealing must not be applied through the
case but, using a suitable tool, only through the spanner flats provided for this purpose at the
square of the connector.
Installation with
open-ended spanner
