0-250 psig, 0.5-4.5 VDC ratiometric 1/8" NPT stainless steel pressure sensor w 3 pin Metri-Pack connector

Part #: E461-0955-1

The Nostrum 250 psi pressure sensor is suitable for use with water, coolant, oil, gasoline, ethanol, methanol and most other automotive fluids as well for gases such as nitrogen and air pressure*. Example uses include fuel pressure measurement, water pressure in water injection systems, coolant pressure and transmission fluid pressure measurements. Like most automotive sensors care should be taken not to mount it in very high temperature locations such as line of sight to exhaust manifolds and turbochargers.

Sensor pressure vs voltage reading for various pressures:

Or if your software needs an equation for the transfer function, here are the transfer functions for the above three units of pressure (where V is the sensor voltage measurement):

PSI = 62.5*V - 31.25

bar = 4.3092*V - 2.1546

 kPa = 430.92*V - 215.46
