Need To Sense Some Fluid Pressure?

Our VP for Sensing Fluid Pressure called this sensor from Kavlico “sweet.” Needs a 5VDC 20mW power source, and will likely put out 0-4VDC, contingent on pressure, from 0-5"/H2O max, we’d say. Measures 1-5/16" x 17/32" on a pair of 7/8" long 5/32" slotted mounting wings. The upper 3/16" OD barb is the low side, and the lower is (ironically) high. Has a 3-pin connector with legend on the back for power and output. Call for a data sheet.
