4. What is the meaning of "Absolute Pressure" in the context of this sensor?

Absolute pressure is measured relative to a perfect vacuum. It is not affected by atmospheric pressure fluctuations.

This differs from gauge pressure, which measures pressure relative to ambient atmospheric pressure.

Therefore, the QBE2003-P10 is ideal for applications involving vacuum conditions or where a true atmospheric pressure reference is needed.

5. What does the 4-20mA output signal signify on the SIEMENS QBE2003-P10?

The 4-20mA output is a standard analog signal representing the measured pressure. 4mA typically corresponds to the minimum pressure in the range (0 bar).

As the measured pressure increases, the output signal linearly scales up to 20mA at the maximum pressure (10 bar).

This widely adopted standard facilitates easy integration with PLCs, controllers, and monitoring systems.

6. Can the SIEMENS QBE2003-P10 be used in hazardous or explosive environments?

The standard QBE2003-P10 is not intrinsically designed for hazardous areas. Specific certifications like ATEX or IECEx are required for such applications.
