How to Order

A typical order number consists of the model number, pressure range, pressure unit, output and mounting connection.

Model	Type	Output Signal	Calibration Pressure
750	D = Differential or Gage*	1-5 VDC	Customer designated exact FSO
		1-6 VDC
		1-10 VDC
		4-20mA
		Custom Output

Example: 750D 4-20mA Cal Pressure = 0-1.5”WC (Model number 750, differential type unit, output signal of 4-20mA, pressure range of 0-1.5”WC)

* With a gage application, one of the two ports is vented to atmosphere
