SIEMENS Pressure Measurement – SITRANS P250 for differential pressure

SITRANS P250

The Siemens Sitrans P250 is a compact single range Transmitter. The Siemens Sitrans P250 is designed for measuring differential pressure. The differential pressure will be detected with a ceramics sensor and transformed into an output signal of 4-20mA resp. 0-5-V.

Accuracy:≤ 1 %
Long-term stability:≤ 0.5 % / 12 months
Measuring range:0 – 100 mbar (0 – 40 inchH2O)
0 – 25 bar (0 – 363 psi)

Product Description:

The SITRANS P250 is a compact single range transmitter for measuring differential pressure. The differential pressure will be detected with a ceramics sensor and transformed into an output signal of 4–20-mA- resp. 0-5-V- resp. 0–10-V. The version with 0-10 V output signal can be connected directly to the LOGO!24 process controller.

The SITRANS P250 transmitter measures the differential pressure of liquids and gases.



Benefits :

  • Connection and housing of high-grade steel 1.4305
  • Ceramic diaphragm
  • High measuring accuracy
  • Sturdy stainless steel enclosure
  • For aggressive and non-aggressive media
  • For the measurement of the differential pressure of liquids and gases
  • Temperature-compensated measuring cell
  • Compact design

Application
The SITRANS P250 transmitter for differential pressure is primarily used in the following industries:
• Chemical industry
• Heating, ventilation and air conditioning technology
• Food industry
• Mechanical engineering
• Shipbuilding
• Water supply

Design
Main components:
• Stainless steel enclosure with piezo-resistive ceramic measuring cell (temperature-compensated) and electronics module
• Process connection made of stainless steel in diverse designs(see Selection and Ordering data)
• Electrical connection through connectors acc. to EN 175301-803-A and round connectors M12, as well as with permanently fixed cable

Function
The pressure transmitter measures the differential pressure of liquids and gases.

Mode of operation

SITRANS P250 pressure transmitter, function diagram The piezo-resistive measuring cell (ceramic membrane) has a Wheatstone bridge circuit, on which the operating pressure P1 and P2 of the media acts at both ends.The voltage output from the measuring cell is converted by an amplifier into an output current of 4 to 20 mA or an output voltage of 0 to 5 or 10 V DC.The output current and voltage are linearly proportional to the input pressure.
