Description

The NovaSensor voltage compensated NPI-15VC

Series offers the performance of our current

compensated sensors with the convenience of using

a voltage supply. Voltage compensation allows

the sensor to be connected directly to the power

supply, thereby eliminating the need for additional

components to construct a constant current source.

calibrated FSO of 100 mV ±1 %.

As with all NPI media isolated sensors, they are

designed to operate in hostile environments and

yet give the outstanding sensitivity, linearity, and

hysteresis of a silicon sensor. The piezoresistive

cavity and isolated from the measured media by

a stainless steel diaphragm and body. The NPI

providing excellent output stability.

The modular design allows for a variety of pressure

port modules which are hermetically welded to the

sensor head module. Standard types A, B, H, and J

are shown to the right.

For compensation of temperature effects, a resistor

network is supplied on a hybrid ceramic substrate.

The

IsoSensor design minimizes temperature errors to

provide a maximum offset error of 1.0% FSO and a

maximum full scale output error of 0.75% FSO over

the

32°F to 158°F (0°C to 70°C) compensated range.
