NPI-15VC Series Specifications
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.
These sensors enable field interchangeability with a
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
sensor chip is housed in a fluid-filled cylindrical
cavity and isolated from the measured media by
a stainless steel diaphragm and body. The NPI
Series employs SenStable® processing technology,
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.
