Description
The PRG are vacuum gauge heads.
The actual pressure sensing element within the gauge head PRG20K - NW16 is a tungsten
filament.
The PRG gauge heads PRG20K - DN16CF and PRG20KCR - NW16 are made of stainless steel
with a welded ceramics feed-through. The sensing element within the PRG20K - NW16 is a
tungsten filament, whereas the PRG20KCR - NW16 uses a platinum filament.
The gauge heads are supplied fully aligned. Any alignment or recalibration will, if at all
necessary, be required only after a longer period of operation.
The gauge heads are temperature compensated for the range from 0 °C to 40 °C.
The measurement cells can be easily exchanged should this be required. After an exchange
of the sensing cell a recalibration is required by adjusting two potentiometers within in the
gauge head.
Product identification
In all communications with Edwards, please specify the information on the product
nameplate.
Validity
This document applies to products with part numbers
The part number (No:) can be taken from the product nameplate.
Intended use
The PRG gauge heads are vacuum gauge heads which are operated in connection with the
operating units PGC201 and PGC202.
The gauge head is used for the measurement of absolute pressures in the rough and fine
vacuum range in accordance with the technical data.
