Our General Purpose flow switches (liquid and gas) reed switches (Option 1S2 or 2S2) are an economical solution for equipment protection and automation for critical processes in a variety of industrial applications. They can be ordered for use in a hazardous location enviroment (Option IS or Option IS-LED). LED’s provide viewing at a glance and easy field calibration. These switches are CSA and ATEX approved and operate in the most demanding environments. Each switch is independently adjustable for ease in configuring a safety interlock or control circuit. Available in threaded and flanged connection.
