The Honeywell TruStability® High Accuracy Silicon Ceramic (HSC) Series is a piezoresistive silicon pressure sensor offering a ratiometric analog or digital output for reading pressure over the specified full scale pressure span and temperature range.
The Honeywell HSC Series is fully calibrated and temperature compensated for sensor offset, sensitivity, temperature effects, and nonlinearity using an on-board Application Specific Integrated Circuit (ASIC). Calibrated output values for pressure are updated at approximately 1 kHz for analog and 2 kHz for digital.
The Honeywell 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.

1 Sensors are either 3.3 Vdc or 5.0 Vdc based on the catalog listing selected.
2 Ratiometricity of the sensor (the ability of the device output to scale to the supply voltage) is achieved within the specified operating voltage.
3 The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.
4 Operating temperature range: The temperature range over which the sensor will produce an output proportional to pressure.
5 Compensated temperature range: The temperature range over which the sensor will produce an output proportional to pressure within the specified performance limits.
6 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.
7 Orientation sensitivity: The maximum change in offset of the sensor due to a change in position or orientation relative to Earth's gravitational field.
8 Full Scale Span (FSS): The algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of the pressure range. (See Figure 4 for ranges.)
9 Insignificant for pressure ranges above 40 mbar | 4 kPa | 20 inH2O.
