805QS Pressure Switch-Transmitter

Brand: Cameron

The 805QS Pressure Switch-transmitter is a compact loop-powered pressure switch-transmitter. A supplemental continuous output is also available (either 4-20 mA or 1-5 Vdc). Its rugged construction makes cost of ownership low and it carries a three-year warranty. The 805QS pressure switch-transmitter is suitable for hazardous locations and hostile environments where space is limited. It meets applications where low-cost, discrete and continuous monitoring is preferred. Switch set points and supplemental continuous output zero and span points are field adjusted via Calibration Kit with USB communication cable.
