Pressure Connection; Measuring Arrangements - WIKA PGT23.100 Betriebsanleitung

5. Installation and commissioning ... 6. Measuring arrangements
Once the pressure and electrical connections have been made, the transmitters
are ready for immediate use.
The A-VA-1 type or KFA6-STR-1.24.500 type feed units may be used to provide
the standard transmitter with DC voltage.
No attempt should be made to remove a pressurised instrument. If the transmitter
cannot be otherwise isolated, the pressure system must be fully vented.
The clamping screws on the top and bottom flanges of diaphragm element
pressure gauges must not be unscrewed.
Any residual pressure medium contained in the pressure
element may be hazardous or toxic. This should be taken
into account when handling and storing pressure gauges
which have been removed.
