Notes:

1.

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

2.

An external bypass capacitor is required across the supply voltage (Pins 1 and 3 – see Figure 4) as close to the sensor supply pin as possible for correct sensor

operation.

3.

Ratiometricity of the sensor (the ability of the output to scale to the input 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 excitation voltage or ground to the wrong pin may cause electrical failure.

5.

The compensated temperature range is the temperature range (or ranges) 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.

Overpressure is the maximum pressure which may safely be applied to the product for it to remain in specification once pressure is returned to the operating

pressure range. Exposure to higher pressures may cause permanent damage to the product.

8.

Burst pressure is the maximum pressure that may be applied to any port of the product without causing escape of pressure media. Product should not be expected

to function after exposure to any pressure beyond the burst pressure.

9.

Total error band is the maximum deviation in output from 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.

Specification units are in percent of full scale span (%FSS).

10.

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.

11.

Consult Honeywell Customer Service for detailed material information.

12.

For the AC pressure port configuration, the “pressure” and “reference” ports are reversed.
