How to Order

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

Model	Pressure Range	Pressure Unit	Output	Mounting Connection
250	100PSI	P = PSI	4 = 4-20 mA* (two wire)	N = 1/4″ NPT
	250PSI
	500PSI
	1,000PSI**
	2,500PSI**
	5,000PSI**
	10,000PSI**

Example: 250G 500P 4 N (Model 250G, 500 PSI pressure range, 4-20mA output, 1/4” NPT mounting connection)
* The 4-20mA output is easily converted to 1-5 VDC utilizing a 250Ω resistor which we will provide upon request.
** Not in Stock. Please allow approximay six (6) weeks for delivery.
