    Our Applied Measurements Pa600SS subsea pressure sensor series are ideal for the measurement of gas and liquid pressure in subsea and offshore applications.  They have a submersible IP68 protection rating for depths of up to 3000m (300bar external pressure) and a UNS S31803 Duplex stainless steel construction as standard.  Greater depths ratings to 8000m/800bar are also available on request.

    Thanks to their wet-mateable 3-pin or 4-pin subsea connector type electrical connection, integrity at 3000m depths/300bar is guaranteed.  Plus, along with their ±0.25% of full-scale accuracy as standard, precision and optimum performance is ensured.  If your application requires even further accuracy, we can also provide a 0.1% optional version.

    Viton O-ring, Duplex stainless steel case, ceramic diaphragm (96% aluminium oxide Al2O3) and a G¼ inch male process connection come as standard with the Pa600SS subsea pressure sensor.  Plus, Applied Measurements can provide alternate case, O-ring material and process connections to suit your requirement.  We can also provide improved thermal zero stability of <±0.02% or <±0.01%/Span/˚C.

    The Pa600SS subsea series provides a wide choice of electrical outputs from its ASIC-based amplifier circuit, these include 4-20mA, 0-5Vdc, 0-10Vdc, 10mV/V and 20mV/V, as well as a ratiometric 0.5-4.5Vdc (10% to 90% of supply voltage) signal that requires a 5Vdc (2.7 – 5.5Vdc acceptable) to suit most dataloggers.

    The Pa600SS subsea pressure sensor series can also be supplied with any of our wide range of instrumentation to give you a complete calibrated system.
