These instructions provide information for installation, electrical connection, process

connection and calibration of 107 Differential Pressure Switches.

107

Differential Pressure Switch

General Instructions

Registered Quality System to ISO 9001

Principle of Operation

Process pressure is sensed by a diaphragm

and piston assembly. The piston responds to

differential pressure and moves a shaft that actuates

(deactuates) an electrical switching element. Low

side pressure and a wetted adjustable range spring

oppose high side pressure. Calibration is accomplished by

adjusting the range spring with the set point adjustment screw.

Design and specifications are subject to change without notice.

Use care during installation not to inadvertently move the electrical switching

element or its housing. Movement of either could disturb the relative positions of

internal working parts and alter calibration or render the device inoperative.

Application

The 107 Differential Pressure Switch is suited for draft range service as well as industrial air and

gas services which are compatible with the wetted parts and within nameplate specifications.

Contact the SOR representative in your area or the factory in Lenexa, Kansas for details.

Installation

The 107 is position sensitive. Mount the 107 so that the diaphragm is vertical (as shown

above). Non-vertical mounting positions will cause calibration scale error.

If condensation is expected within process piping, pressure ports should be located at 6

o’clock to prevent moisture accumulation within the instrument. If condensation is not

expected, the pressure ports can be positioned to any location as long as the diaphragm

remains vertical.

Securely mount the base plate bracket to flat surface using suitable bolts.
