LP650 pressure transducer M12


  • Measuring range from 10 to 700 bar FS
  • Monolithic construction with strain gauge measuring element
  • Available with signal 2m/V, 0-5 V, 0-10 V or 4-20 mA
  • Built-in M12 5-pole male A connector
  • Strong, reliable and inexpensive


Ranges (relative reference): from 0 up to (2,5)-(5)-10-20-50-100-200-250-350-500-700 bar.

– 2,5 and 5 bar FS are made only with Mod. LP655 (5V output).
– 1100 and 1400 bar FS are to be used with liquids with line pressure of 700 /800 bar and hammershocks overimposed.


  • Mod. LP652: 2mV/V.
  • Mod. LP655: 5V .
  • Mod. LP651: 10V.
  • Mod. LP654: 4-20 mA.

Non linearity: < ± 0,2% FS bsl.
Environmental protection: IP65.

Series LP650 can be used in hydraulic / pneumatic cylinders, presses, machine tools, force control in actuators, quality contol machines, test benches, level measurement, food industry, chemical industry, water reservoirs, vehicles,power plants and wherever an heavy use is involved.

Series LP650 ensure the best long term stability because of its strain gauge technology.

Full scales:
– 2,5 and 5 bar FS are made only with Mod. LP655 (5V output).
– 1100 and 1400 bar FS are to be use with liquids with line pressure of 700/800 bar and hammershoks overimposed.

Series LP650 has an extremely rugged pressure gate 1/4 “Bsp:
– It is one piece of machined high tensile stainless steel with no welding of the diaphragm together with the pressure gate (that would be a weak point).
– Hardening treatment: It makes the metal more protected against overpressures and a dynamic use.
– The metal of the pressure gate has been remelted under consumable electrodes in order to avoid the chemical impurities inside the alloy.
– A special profile of the peripherical edge of the diaphragm: to avoid fatigue yelding.

A calibration certificate is provided together with every unit.
Series LP650 has a built in calibration circuitry activated by an external permanent magnet (provided together with the unit) that allow an easy calibration together with an external electronics.

Mod. LP655, LP651 and LP654 have a built in amplifier with the following features:
– High immunity against electromagnetic noise because of CE marking (under the more severe standards and test conditions) and a very high common rejection ratio of the operational amplifier.
– Zero trimmer regulation.
– A negative polarity generator feeding the operational amplifier allow the transducers to measure also a vacuum thence giving a negative signal.
