Transmitters Modus Model RPM1 - GE General Eastern The Modus room pressure monitor takes advantage of our time-proven sensor technology to monitor, alarm and/or control critical room to room differential pressures. The same instrument monitors either positive or negative room pressures. Monitoring of hospital rooms such as operating rooms and isolation rooms for housing contagious patients is a typical application. Other applications requiring differential pressure monitoring are: fume hoods, clean rooms, computer rooms, asbestos abatement projects etc. This monitor is extremely sensitive and performs reliably at very low room pressures.   Product Description It is easily mounted on a wall and the installer has the choice of rear or bottom knockouts for electrical and pressure connections. All electrical and mechanical components are housed in a tough polycarbonate NEMA type 13 (IEC529, IP65) enclosure with a clear, gasketed polycarbonate cover for easy viewing of display and room status. Pressure is displayed on the front panel with a resolution of 0.001" of water (or 0.1 Pascals). The unit measures positive or negative pressure. A minus sign indicates a negative room pressure. A small light, next to the digital display, indicates the selected units of measurement (inches of water or Pascals). A bright red and a bright green LED alert those approaching of the status of the room. The pressure at which the lights change state can be adjusted from the front panel. The room pressure monitor comes standard with a SPDT relay (for supplemental controls such as audible alarm or remote status indication), and 3 analog output signals, 0 to 5 Vdc, 0 to 10 Vdc and 4 to 20 mA. These analog outputs are proportional to the room pressure. A selector switch allows field setup for either 120 Vac or 240 Vac 50/60Hz service. 24 Vac operation is optional.
