These quality differential pressure gauges
are designed to measure the difference in pressure between two
points in a system and show it on a single dial gauge. A magnetic
movement senses the differential pressure. The gauge has separate
pressure and indicating chambers.
Diaphragm instruments
can indicate small values of differential pressure even when
used at high line pressures. They provide instantaneous and continuous
information regarding system conditions helping in eliminating
premature servicing of equipment, avoid unscheduled down time
of costly processes and detect abnormal system conditions. Gauges
can be supplied with reed switches to initiate alarms, activate
other equipment, or shut the system down. Two switches are used
when high and low limits are desired. Gauge-switch models provide
the user with both gauge readout and switch operation. |
