Orange Research differential pressure
gauges are designed to measure the difference in pressure between
two points in a system and present the resultant differential
pressure directly on a single gauge dial. A patented magnetic
movement allows the simultaneous sensing of both pressures while
completely isolating the gauge function from the pressure chamber
without the use of mechanical seals.
Unlike ordinary pressure gauges,
Orange Research gauges can indicate small values of differential
pressure even when used at high line pressures. Orange Research
differential pressure switches are supplied
with reed switches or relays to initiate alarms, activate other
equipment, or shut the system down. Two switches are installed
when high and low limit control is desired.
Orange Research has developed a
series of differential pressure transmitters with the ability
to transmit data signals. The microprocessor based instruments
are equipped with unique Hall effect sensors that convert the
gauges' normal magnetic movements into electric signals. After
processing, the units provide analog and digital electronic output
for remote location monitoring. Since the usual pointer-and-dial
gauges continue to operate, local station readout is always available.
Users can select current, voltage,
frequency, or RS-232 serial communications signals plus two independently
adjustable relay outputs. Connections to displays, monitors, and
controllers are made via standard 3 or 4 wire cable.
