Installation Instructions for the
Heavy Duty Pressure Transducers
PX3 Series, 1 bar to 50 bar | 15 psi to 700 psi
32313758
Issue B
General Information
Honeywell’s PX3 Series Pressure Transducers use piezoresistive
sensing technology with ASIC (Application Specific Integrated
Circuit) signal conditioning in a brass housing and Metri-Pack
150 electrical connector. The PX3 Series are fully calibrated and
temperature compensated from -40 °C to 125 °C [-40 °F to
257 °F].

Dependent on external and internal seal and cable jacket materials. See Table 5 and Figure 5 for temperature range details.
2
Total Error Band: The maximum deviation from the ideal transfer function over the entire compensated temperature and pressure range. In-
cludes all errors due to offset, full scale span, pressure non-linearity, pressure hysteresis, pressure non-repeatability, thermal effect on offset,
thermal effect on span, and thermal hysteresis. See Figure 1.
3
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 pressure non-repeatability. See Figure 1.

Turn on Time: Duration from power applied until first valid output.
