Product Announcement from Orange Research, Inc.
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.
