High Temperature Pressure Sensor | 150ºC | Pa600HT

At a Glance

Description

Applied Measurements Pa600HT high temperature pressure sensor is specifically designed to measure the pressure of hot gases and liquids.  The Pa600HT’s unique cooling coils effectively dissipate heat between the hot wetted media end and the pressure diaphragm located at the other end the cooling coils, in an ambient temperature environment.

The Pa600HT sensor housing is constructed from 303 stainless steel and utilises a ceramic sensing diaphragm (96% aluminium oxide Al2O3), a Viton O-ring and a G¼ inch male process connection as standard making it suitable for a multitude of common sensing applications.

Should you require a pressure sensor tailored to your specific pressure measurement application, we can design and manufacture fully-customised sensors for you – please contact our friendly sales team to discuss your requirement in detail. We can easily accommodate any requirement from a one-off to bulk orders for many thousands of sensors, all within our in-house, UK production facility.

A wide variety of outputs can be offered from Applied Measurements Pa600HT high temperature pressure sensor including 4-20mA, 0-5Vdc, 0-10Vdc, 10mV/V and 20mV/V.  It’s also available with a ratiometric 0.5-4.5Vdc signal (10% to 90% of supply voltage) that requires a 5Vdc regulated supply to suit most data loggers.

Applied Measurements has a range of precise instrumentation that can be used with the industrial pressure sensor to give you a complete calibrated pressure measurement system.
