From now on, measure pressure absolutely

New PT absolute pressure transmitter with different measuring ranges

  • Measuring range 0...1/1,6/4/10 bar absolute and analogue output 4...20 mA
  • Robust stainless steel measuring cell
  • Slim, compact design with G 1/4 process connection
  • Measuring accuracy ≤ 0.8 %, repeatability ≤ 0.1 %
  • Easy connection via M12 connector

Absolute pressure sensors
As of now, ifm has added absolute pressure sensors to its versatile portfolio in the pressure sensor range. The new PT05 series with robust metal measuring cell, G 1/4 process connection, M12 connector and analogue output is available in the common pressure ranges up to 10 bar.

Operating principle
Absolute pressure sensors operate independently of the surrounding air pressure; that is what distinguishes them from sensors working on a relative measurement principle. The measurement is not influenced by weatherand
altitude-related fluctuations of air pressure. This is often a decisive factor in vacuum applications, which require a fine pressure control. Absolute pressure sensors do not require ventilation, therefore incorrect measurement due to a blocked exhaust is impossible. In the field of pressure sensors the new units stand out as specialists for ”specific duties“.
