511-624-520 PRESSURE DIFFERENTIAL SWITCH ( FS-6330-527 ) WEIL-MCLAIN

The WEIL 209674 511-624-520 PRESSURE DIFFERENTIAL SWITCH ( FS-6330-527 ) is a genuine WEIL-MCLAIN part, which is suitable for use with a variety of equipment.

The MCLAIN 511-624-520 PRESSURE DIFFERENTIAL SWITCH ( FS-6330-527 ) is from WEIL MCLAIN

The FS6330527 is a Pressure Differential Switch used in the Weil-McLain water-tube boilers with 515-series and early 516-series processors in natural gas and propane applications for heavy duty applications.

With a pressure differential switch, the Weil-McLain 209674 provides control for heating and air conditioning with a low differential and better temperature control. Designed to be used in applications that require HVAC power to operate based on the differential between the demand and supply pressures.

The switch is preassembled with 2 wire leads, and can be mounted on the inlet or outlet side of the tank. This product has been superseded by the 511-624-514 PRESSURE SWITCH.

The FS 6330 is a 30-psig pressure differential switch that activates in response to a current or temperature drop in the term-to-term lines. Units are packaged hermetically with copper alloy bodies, stainless steel mounting hardware and plastic spacers. Full magnetic circuit provides the fastest response to pressure drop across the load. Pressure ranges are monitored without any need for calibration. Optional operating elements include solid state devices, thermistors and other special materials. Switch contacts are rated at 3 amps @ 250VAC/DC. AL options include:

Pressure Differential Switches are used to detect a change in pressure within a fluid flow. This switch is used on the high side of the solenoid in the application of an air compressor or refrigeration cycle system. The switch senses the pressure increase that may occur because of the exposed absorbent surface area when a filter dries out. When this happens, the pressure is relieved by activating an auxiliary device, such as a water separator or filter bypass valve.
