Notes:

1.

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

2.

Ratiometricity of the sensor (the ability of the device to scale to the 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

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.
