Boiswood, the specialist distributors of components for gas and liquid control, are now supplying the Setra range of GCT-225 pressure transducers with NPT connections, enabling this proven technology from the semiconductor industry to be specified for other gas and liquid measurement applications.

The low cost, GCT-225 offers excellent resistance to environmental extremes, making it ideal for pressure measurement applications in high purity gas delivery systems.

The units, which feature Setra's proven capacitive sensing technology, are virtually EMI/RFI immune.

The design offers accuracy of +/-0.25%FS and full scale pressure output of 0.2 to 5.2 VDC or 4-20 mA output.

Extreme stability ensures that costly downtime is avoided.

The GCT-225 measures pressures from 0-25 to 0-3000 psig, or psia and compound pressures of -14.7-25 to -14.7-3000 psig.

It has been designed with a low internal volume (0.11 in3) that can be easily purged and all wetted parts are manufactured in high quality VAR 316L stainless steel, electro-polished to 7 Ra finish.

Units are supplied with a rotatable cover for easy access to 12 turn potentiometers for fine zero and span adjustment.

A standard swivel male or female, face seal pressure fitting allows direct pipe mounting and a 6-foot multi-conductor cable or 4-pin bayonet connector is available for electrical termination.
