DESCRIPTION
The TruStability® High Accuracy Silicon Ceramic (HSC) Series
is a piezoresistive silicon pressure sensor offering a digital
output for reading pressure over the specified full scale
pressure span and temperature range.
These sensors measure absolute, differential, and gage
pressures. The absolute versions have an internal vacuum
reference and an output value proportional to absolute
pressure. Differential versions allow application of pressure to
either side of the sensing diaphragm. Gage versions are
referenced to atmospheric pressure and provide an output
proportional to pressure variations from atmosphere.
The HSC Series is fully calibrated and temperature
compensated for sensor offset, sensitivity, temperature effects,
and non-linearity using an on-board Application Specific
Integrated Circuit (ASIC). Calibrated output values for pressure
are updated at approximately 2 kHz.
The TruStability® pressure sensors are intended for use with
non-corrosive, non-ionic gases, such as air and other dry
gases. An available option extends the performance of these
sensors to non-corrosive, non-ionic liquids.
The HSC Series is calibrated over the temperature range of
0 °C to 50 °C [32 °F to 122 °F]. The sensor is characterized for
operation from a single power supply of either 3.3 Vdc or
5.0 Vdc.
All products are designed and manufactured according to ISO
9001 standards.
