ProSense FSD Series flow switches monitor liquid media and provide reliable flow detection for various flow applications. The series' sensing principle ensures fast response time and allows for a more precise set point setting. The switches are ideal for applications with rapid temperature changes or where fast response time is required, such as machine tool coolant flow, HVAC cooling water flow and injection molding cooling water flow. Available in two 24 Vdc models, FSD Series switches are available in 0.26 to 26.4 GPM or 1.32 to 26.4 GPM sensing ranges, and feature a fast response time of 10 ms.
