Robust and cost-effective SQ series high-pressure switchesImpress Sensors & Systems Ltd is expanding its range of SQ 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 are user-adjustable between 50 and 100 bar.

Impress Sensors & Systems says these switches are a cost-effective and robust option for OEMS and end users for 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 mechanical pressure switch range 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.

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 G1/4inch male process connection.

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

Sam Drury, Sales & Marketing Director at Impress Sensors & Systems, 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 100bar. 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."
