Description
Siemens Pressure Sensor QBE2003-P4
Use:-
The pressure sensors are suitable for the measurement of relative pressure in HVAC plants, particularly in hydraulic and pneumatic systems using liquid or gaseous media
(steam applications).
Mode of operation:-
The pressure sensors operate on the piezo-resistive measuring principle. The ceramic or stainless steel diaphragm*) (thick-film hybrid technology) acquires the pressure through direct contact with the medium. The measurement is converted electronically into a linear output signal of DC 0…10 V or DC 4…20 mA.*) Applies to QBE2003-P10, QBE2003-P16, QBE2003-P25, QBE2103-P10, QBE2103-P16, and QBE2103-P25.
Mechanical design:-
• Sensor hood with DIN EN 175301-803-A plug-in connection
• Piezo-resistive measuring element integrated into the stainless steel case
• Pressure connection external thread G ½” and inside thread M5*) for use with accessory AQB2001**)
• Plug DIN EN 175301-803-A (plugged in)
No changes or adjustments are possible.*) The following types do not have M5 inside threads: QBE2003-P10, QBE2003-P16, QBE2003-P25, QBE2103-P10, QBE2103-P16, and QBE2103-P25 **) Cannot be used on types QBE2003-P10, QBE2003-P16, QBE2003-P25, QBE2103-P10, QBE2103-P16, and QBE2103-P25. A solution on the construction side using the ½” threaded connection is possible.
