ProSense® Flow Switches

FSD Series Flow Switches

The ProSense FSD Series flow switch sensor utilizes a spring-supported piston that is lifted by the flowing medium. The piston position is detected via an inductive sensor and is output as a digital signal. The spring resets the piston to its initial position with decreasing flow. This allows the sensor to be mounted in any position (horizontally or vertically) and function as a check valve.

• The ProSense FSD Series flow switches monitor liquid media and provide reliable flow detection for various flow applications.
• The flow switch sensing principle ensures extremely fast response time and allows for a more precise setpoint setting. The setpoint can be easily set and locked with a setting screw.
• FSD Series flow 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
  • Injection molding cooling water flow

Features

• Two flowrate models are available:
  • - 0.26 to 6.6 GPM setpoint range, 26.4 GPM max flow rate, 3/4" NPT process connection
