Featuring a flow rate LEARN function for easy setup, the SI flow switch lets operators quickly teach the switch high and low flow rates. The setpoint alarm can be positioned at any value from 1% to 99% of the high flow rate. Various modular mounting options let users position LEDs to the best viewable position. This switch has a lockout function that prevents any unintentional changes to the setup and, using a µP, operators can adjust and set up the switch remotely from a pushbutton or PLC. Maximum pressure is 4350 psi and temperature response rate is 572°/V/minute. The high pressure rating provides reliable operation in applications that exhibit pressure spikes due to valve closings.
