Description

The unique electric switch design in the Series 1640 Floating Contact Null Switch for High and Low Actuation is another Dwyer Instruments, LLC innovation. The Dwyer Model 1640 Differential Pressure Switch resembles the high precision large diaphragm Series 1630 switches. However, the Model 1640 is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch.
Floating contact null switch, range 0.2-1.0" w.c., adj. null span, .02 min. set, .06 max. Set.
