DESCRIPTION
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. 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 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. 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 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. All products are designed and manufactured according to ISO 9001 standards.

- Absolute maximum ratings are the extreme limits the device will withstand without damage.
- Ratiometricity of the sensor (the ability of the digital device to maintain performance parameters independent of supply voltage) is achieved
within the specified operating voltage for each option.
- The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.
- The compensated temperature range is the temperature range over which the sensor will produce an output proportional to pressure within
the specified performance limits.
- The operating temperature range is the temperature range over which the sensor will produce an output proportional to pressure but may not
remain within the specified performance limits.
- Accuracy: The maximum deviation in output from a Best Fit Straight Line (BFSL) fitted to the output measured over the pressure range at
25 °C [77 °F]. Includes all errors due to pressure non-linearity, pressure hysteresis, and non-repeatability.
- Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range.
