Series 104

Benefits

High Quality, Low-Cost
Visual Set Point Indication
Hassle-Free Field Adjustment Knob
2% Repeatability

The Series 104 Differential Pressure Switch is a low-cost easy to use switch for very low pressure applications. The switch can monitor positive, negative, or differential pressure and with an easy to adjust set point knob makes field set up and adjustment hassle free. The differential pressure switch includes a SPDT relay rated for 2A @ 250V and can be set as low as 0.08″ w.c. (20 Pa)
