The P600HT industrial high temperature pressure sensor is designed for the measurement of pressure across a wide range of general-purpose and industrial applications including hydraulics, medical, research and development and a range of steel manufacturing and preparation processes where media temperatures of up to 250ºC are present.

The P600HT high-temperature pressure sensor offers superb media compatibility as standard with its all-Titanium Alloy pressure port and sensing element.  The process connection is a ½” BSP male with flush 316L diaphragm for applications such as food processing, pharmaceutical and petrochemical, where a hygienic flush
diaphragm is needed.

Additionally, the electronics of the high-temperature pressure sensor are thermally insulated from media temperatures of up to 250°C.

This high temp pressure sensor features an FFKM o-ring which provides excellent chemical resistance along with excellent gas and liquid permeation resistance. The FFKM O-ring enables operation in higher temperature applications.

ATEX-approved versions of this high temperature pressure sensor are also available with a 4-20mA output version only.

The P600HT high temperature pressure sensor provides a 2-wire 4-20mA electrical output as standard, while 0-5Vdc and 0-10Vdc are optional.
