Loop-Powered Controller Is Explosion Proof

Housed in a compact, explosion-proof package with dimensions of 1" x 1.5" x 2", EP900 Series of loop-powered (4 to 20 mA) controllers has a glass window for the optional LCD meter and three 1/2" NPT ports. The display and controls can be rotated 360° inside the housing, so there are no position limitations. Available in 13 models, any one of the series can be equipped with or without the 3-1/2-digit display and with or without signal conditioners (or sensor/transducer) for pH, ORP, V/mA dc, V/A rms, RTD or TC temperature, strain-gage or microvolt and frequency measurements. Models with a built-in sensor include humidity, pressure-vacuum, vibration, acceleration, shock and positioning types. Within the series, users can get just a loop-powered display, a process transmitter, a loop controller or a combination of all three depending upon requirements.
