Silicon Pressure Sensors, Digital Output

GENERAL INFORMATION

TruStability Standard Accuracy Silicon Ceramic (SSC) Series are piezoresistive silicon pressure sensors offering a digital output for reading pressure over the specified full scale pressure span and temperature range. They are available in standard pressure ranges from 1 psi to 150 psi (60 mbar to 10 bar) and are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases. The liquid media option extends the performance of these sensors to con-corrosive, non-ionic liquids.

CAUTION

PRODUCT DAMAGE

• Ensure liquid media is applied to Port 1 only; Port 2 is not

compatible with liquids.

• Ensure liquid media contains no particulates. All

TruStability can accumulate inside the sensor, causing damage or affecting sensor output.

• Recommend that the sensor be positioned with Port 1

facing downwards; any particulates in the system are less likely to enter and settle within the pressure sensor if it is in this position.

• Ensure liquid media does not create a residue when dried;

build-up inside the sensor may affect sensor output. Rinsing of a dead-ended sensor is difficult and has limited effectiveness for removing residue.

• Ensure liquid media are compatible with wetted materials.

Non-compatible liquid media will degrade sensor performance and may lead to sensor failure.

Failure to comply with these instructions may result in product damage.

See soldering times and temperatures in Table 2.

CLEANING

CAUTION

IMPROPER CLEANING

• Ensure cleaning fluids, such as appropriate alcohols or

fluorinated solvents, are used based on the type of contaminants to be removed.

• Do not immerse the sensor.

Failure to comply with these instructions may result in product damage.

Notes:

1. Life may vary depending on specific application in which the sensor is utilized.

2. Absolute maximum ratings are the extreme limits the device will withstand without damage.

3. 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. Other custom supply voltages are available, please contact Honeywell Customer Service.

4. The sensor is not reverse polarity protected. Incorrect application of supply voltage or ground to the wrong pin may cause electrical failure.

5. The compensated temperature range is the temperature range over which the sensor will produce an output proportional to pressure within

the specified performance limits.

6. 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.

7. 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.

8. Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range.

Includes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, repeatability, thermal effect on offset, thermal effect on span, and thermal hysteresis.

9. Full Scale Span (FSS) is the algebraic difference between the output signal measured at the maximum (Pmax.) and minimum (Pmin.) limits of

the pressure range. (See figure 1 for ranges).
