How to Order

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

Model	Type	Output Signal	FSO Pressure Range	Calibration Pressure
865	D = Differential or Gage*	0…..1 to 5 volts	0…..0.25″WC to 5″WC	Customer designated exact FSO
		1…..1 to 6 volts	1…..>5″WC to 13″WC
		2…..1 to 10 volts**	2…..>0.5PSI to 1PSI
		3…..4-20mA (250Ω load)	3…..>1PSI to 5PSI
		4…..4-20mA (500Ω load)**	4…..>5PSI to 15PSI
		5…..Custom Output

Example: 865D-01 Cal Pressure = 6” WC. “Pressure Range” is not a specific number. Please indicate exact calibration pressure. (This unit has an output of 1-5 VDC and will be calibrated to 6” WC.) If a custom output is needed, the exact output must be specified.

* With a gage application, one of the two ports is vented to atmosphere
** With a 1-10 VDC output as well as with a 4-20mA output that needs to drive a 500Ω load a 18-24
VDC/24VAC input is required.
