GENERAL  
®
PSW-180 Teflon differential pressure switch  
utilizes a diaphragm sensor to monitor pressure  
changes. The switch utilizes dual diaphragm  
sensors to monitor the difference in pressure  
manufacturers recommendations. Cut tubing. Slip  
nut over tubing. Flare tubing. Press tubing onto  
pressure connection, making certain tubing is  
seated on pressure connection shoulder. Tighten

between two sources. PFA Teflon wetted ports  
insure corrosion resistance in highly corrosive  
applications and is well suited for high purity  
applications.  
Dimensions  
Minimum torque requirement for 1⁄4” nut is 5  
inch • pounds (0.57 Newton • Meters). Be sure  
to connect high pressure source to port labeled  
“HIGH.” Connect low pressure source to “LOW.”
