Fixed Set-Point Flow Switches
Our 30000 Series fixed set-point flow switches have factory-preset
settings. The many features and the adjustability found on our other
models have been designed out.
Their compact size and basic profile results
in low-cost switches that can be mounted where space is limited. This
makes them popular for OEM applications where simple flow switch
actuation is required.
Rugged materials are used to allow for long-term, high-pressure use. The
switches are popular for portable systems where shock and vibration are
common. Stainless steel springs and brass or stainless steel pistons and
pressure bodies allow for use in a variety of applications, including
lubricating systems, chillers, coolers and heat exchangers.
How It Works
Designed for in-line use, the fluid enters
the end connection and exits the side port. As the fluid passes through
the unit it pushes against a spring-loaded piston magnet sensor. As the
sensor magnet moves into proximity of the reed switch, the switch is
activated.
Calibration
The switches are calibrated on
increasing flow in the vertical position on water at 70 F. For other
fluids or conditions special calibration is available. In this case,
specify orientation, fluid, specific gravity and viscosity.
