WIKA FSM-6100 Flow switch For industrial heat exchangers

Original price was: $500.00.Current price is: $450.00.

The FSM-6100 electromechanical flow switch detects interrupted flow (“no flow”) of water and non-corrosive liquids in industrial coolers, heaters, or pipelines. It prevents system failures (e.g., ice formation from lack of cooling flow) via operational controls.

Housed in a plastic case with IP30 ingress protection, it features UL-listed microswitches and protective bellows for durability and long service life. Suitable for pipe sizes 25–150 mm (1–6 in), it supports various non-critical media applications. Cost-effective and reliable for continuous operation.

Applications

  • Heating, cooling, air-conditioning and water treatment plants
  • Pumps and dosing systems
  • Operational controls to prevent system failures in the absence of supply of water or liquid

Special features

  • Switch point repeatability of ±5 % for reliable switching
  • High-quality bellows and microswitch for a service life of > 500,000 cycles
  • Rigid paddles from stainless steel to withstand pressure surges and high medium temperatures

Description

The model FSM-6100 electromechanical flow switch is designed for the detection of interrupted flow (“no flow”) of water and other non-corrosive liquids in industrial coolers, heaters or other industrial pipelines.

The flow switch signal is used for operational controls that prevent system failure, e.g. due to ice formation in the absence of cooling water flow.

The cost-effective flow switch is enclosed by a plastic case. The ingress protection of IP30 protects it from unwanted ingress of foreign bodies.

The model FSM-6100 is equipped with UL-listed microswitches and protective bellows to ensure high durability with continuous operation and a long service life.

The range of flow ranges, with pipe sizes from 25 … 150 mm [1 … 6 in], enables use for flow measurement in a variety of applications with non-critical media.
