Typical Applications
The pneumatic pressure transmitters are designed to measure either air
or fluid pressures. All models transmit a fixed-span, 3 to 15 psig output
signal proportional to input pressure to controlling and indicating devices
such as receiver-controllers, receiver gauges, and certain pneumatic
relays and alarm devices. These transmitters are available in various
pressure ranges to meet most control system application requirements.
Features:
• Single-input pressure transmitter permits remote readout on receiver gauge, and
control of air, water, steam or refrigerant pressure from a convenient location.
• Three different ranges permit proper match of transmitter range to application.
• Quality design and construction assure linearity and responsiveness.
• Factory-adjusted span and “zero”.
• Field-assemble “zero” adjustment.
