Description
The Oceanic Systems 4620 is a compact stainless steel vacuum sensor that measures pressures from 0 to -1 bar and outputs a standard 4-20mA signal. It uses a high performance piezoresistive transducer with a silicone oil filled, O-ring sealed internal structure, giving high stability and enhanced anti-interference and surge protection across a wide range of marine liquids and gases.
The rugged stainless steel body carries a G1/2 inch BSP pressure connection and a direct cable output, and the sensor has a -10 to 70 degrees C compensated temperature range. Paired with an Oceanic Systems 4601 4-20mA Pressure Adaptor it reports pressure onto the NMEA 2000 network for display on any compatible instrument.
