INTRODUCTION
The Dynisco PG540/PG550 Series pressure gauges are highly
engineered, electronic devices. With proper installation and handling
these units will provide years of care-free service.
The tip of the gauge consists of a stainless steel diaphragm. Care must
be taken to protect the diaphragm from severe abrasion, dents and
gouges. During storage the protective cap supplied with the unit
should be left in place.
1.1
Gauge Probe Mounting Hole
The gauge probe is machined to tight dimensional tolerances. To avoid
damage on installation, the mounting hole should be carefully
machined and checked for the correct dimensions.
A set of mounting hole machining tools is available (P/N 200925) to
assist in preparation of the mounting hole.
The mounting hole should conform to the recommended dimensions
shown in Figure 2, below.
