ProSense FSD series mechatronic flow switches monitor liquid media and provide reliable flow detection for various process applications. Immune to rapid media temperature changes, these switches have a fast 10ms response time and are well-suited for high duty-cycle applications (10 million cycle life).
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
Two flowrate models are available:
- 0.26 to 6.6 GPM setpoint range, 26.4 GPM max flow rate, 3/4" NPT process connection
- 1.32 to 26.4 GPM setpoint range, 52.8 GPM max flow rate, 1" NPT process connection
Immune to rapid temperature changes of media
Fast response time of 10ms: great for cycling
applications with a minimum of 10 million switching cycles
Easy to set: turn dial to desired setpoint
Able to be bench set outside the process
3/4" or 1" NPT process connections
Integrated check valve design allows the sensor to be
mounted horizontally or vertically
4-pin M12 quick disconnect
