Impress expands mechanical pressure switches to include high pressure series

Instrumentation specialist Impress Sensors & Systems Ltd has expanded its SQ range of mechanical pressure switches to include a high pressure series, which is adjustable between 50 and 100 bar.

The new SQ high range mechanical gauge pressure switches are available in three versions: the cost effective SQ275-RH1 zinc-plated SPDT (single pole, double throw) pressure switch; the SQ276-RH1 stainless steel SPDT version for media compatibility; and the SQ27U-RH1 brass SPDT pressure switch. All three switches are user-adjustable between 50 and 100 bar.

The switches are a cost effective, robust option for OEMS and end users across a diverse range of process control applications, including pressure control for piping systems, lubrication systems, hydraulics and pneumatics, air compressors, hydraulic detection for fire fighting systems, sprinkler systems, medical equipment, and tyre manufacturing.

The SQ range of mechanical pressure switches from Impress Sensors also includes a medium pressure series. With similar technical features to the high pressure range, these switches are available in zinc-plated, brass and stainless steel housings, with adjustable pressure ranges between 20 and 49 bar.

The SQ high range pressure switches have NBR diaphragms as standard, with Viton and EPDM diaphragms available as options. Electrical connection is made by simple spade terminals and the switches have a G1/4" male process connection.

The switches can operate in temperatures from -10 deg C to +100 deg C. Response frequency is 2Hz and accuracy is +/- 5% FS.

Sam Drury, Sales & Marketing Director at Impress Sensors & Systems Ltd comments: "By introducing the high range SQ switches into our existing range of mechanical pressure switches, we can now offer customers robust, user-adjustable pressure switches from
5mbar up to 100 bar. Different housing materials, diaphragms and selectable contacts, allows us to cater for every customer's needs, from harsh, media compatible environments through to simple low cost mechanical switches for non-process critical applications."
