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