Watertown, MA - The Precision Sensors Division of United Electric Controls introduces a new concept in pressure monitoring and control of critical interlock functions. The new staset^® solid-state pressure switch offers the safety and simplicity of a switch, the output of a transducer and the convenience of a gage in a single, compact package. Solid-state technology enables staset^® to provide superior accuracy and repeatability when compared to traditional switches, while a local display and status LED facilitate installation, calibration and trouble shooting. Staset's^® ultra high purity construction makes it ideal for applications such as semiconductor fabrication equipment and gas delivery systems. Best of all, staset^® is about half the cost of equivalent high purity, indicating pressure transducers.

Until now, instrument engineers at equipment OEMs and end-users have been forced to choose between extremes by using either a non-indicating, mechanical pressure switch or a higher-cost electronic pressure transducer to monitor and control important threshold pressures. Now there is a complete solution - staset^®. Simple and full-featured, staset^® utilizes proven solid-state pressure sensing technology to provide an improved switch with longer life and greater accuracy. In addition to the switch output, staset^® is available with a 0-5 VDC analog process signal. A local status LED provides indication of the switch output while a LCD display enables continuous monitoring of the process variable. Other advantages of staset^® include reduced space requirements, reduced internal volume and fewer potential leak paths due to a reduced number of intrusions into the process.

Staset^® is UL recognized for added safety. The switch output is fail-safe upon loss of power. Set point and deadband are factory-set, for true tamper-proof operation. The switch output can be set to trip from 8 Torr to 100 psig, while the deadband can be set up to 98% of the range. Measurement ranges from 760 Torr to 100 psig are available. Available process connections include both male end-seal (9/16-18 thread) and flush-mount (SEMI spec 2787.1 or 2787.2) versions. Both types of connections are fabricated from VAR (Vacuum Arc Re-melt) 316L SCQ stainless steel. Wetted surfaces are electropolished to a 5 Ra finish.
