Orange Research, Inc. Fixed Set-Point Flow Switch 30144

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 a Flow Switch 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. Flow Switch 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. Features Compact size Low cost OEM design Brass or stainless steel
