Description
The new digital pressure sensor 23SXc KELLER is a version of the proven 23SX with an updated CANopen interface. Performance, reliability, and compatibility with the 23SX environment combined with the CANopen interface offer users greater flexibility in their measurement chain.
CANopen is a communication protocol based on CAN (Controller Area Network), ideally suited for integration into a wide range of automation solutions. CANopen is defined and standardized in the European standard EN-50325-4, which means users no longer need to worry about details related to CAN.

| Pressure | ||
| Accuracy at room temperature (20…25°C) | ≤ ± 0.1% FSO Option: ≤ ± 0.05% FSO | Linearity (best fit straight line), pressure hysteresis, repeatability, zero offset, gain factor |
| Total error (-10…80°C) | ≤ ± 0.25% FSO | Maximum deviation within compensated pressure and temperature range. Experience shows that outside the compensated temperature range, the total error within the ambient temperature range increases by 0.1% FSO. |
| Compensated temperature range | -10…80°C | Option: Other additional temperature ranges possible within -40…125°C |
| Long-term stability | ≤ ± 0.15% FSO | Per year under standard conditions, annual recalibration recommended |
| Position dependence | ≤ ± 1.5 mbar | Calibrated in vertical mounting position with downward threaded connection |
| Resolution | 0.002% FSO | |
| Signal stability | 0.01% FSO | No noise |
| Internal measurement frequency | ≥ 1800 Hz | |
| Pressure range margin | ± 10% | Outside the pressure range margin, +Inf / -Inf is displayed. In case of device error, NaN is displayed. |
| Vacuum resistance | For operating pressure ≤ 0.1 bar abs., a vacuum-optimized version is recommended. | |
| Temperature | ||
| Accuracy (-10…80 °C) | ≤ ± 2°C | Temperature is measured on the pressure sensor (silicon chip) located behind the metal separating diaphragm. Values are valid within the compensated temperature range. |
| Resolution | ≤ 0.01°C | |
| Internal measurement frequency | > 10 Hz | |
