DESCRIPTION

The TruStability Standard Accuracy Silicon Ceramic (SSC)

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 SSC 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 SSC Series is calibrated over the temperature range of

-20 C to 85 C [-4 F to 185 F]. The sensor is characterized

for operation from a single power supply of either 3.3 Vdc or

5.0 Vdc.

FEATURES

Industry-leading long-term stability

Extremely tight accuracy of 0.25% FSS BFSL (Full Scale

Span Best Fit Straight Line)

Total error band of 2% full scale span maximum

Modular and flexible design offers customers a variety of

package styles and options, all with the same industry-

leading performance specifications

Miniature 10 mm x 10 mm [0.39 in x 0.39 in] package

Low operating voltage

Extremely low power consumption

I C- or SPI- compatible 14-bit digital output (min. 12-bit

sensor resolution)

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.

Precision ASIC conditioning and temperature compensated

over -20 C to 85 C [-4 F to 185 F] temperature range

RoHS compliant

Virtually insensitive to mounting orientation

Internal diagnostic functions increase system reliability

Also available with analog output

Notes:

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

2. 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.

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

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

the specified performance limits.

5. 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.

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. 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.

8. 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.)

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

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 sensors are dead-ended devices. Particulates 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.
