Pressure transmitters for RELATIVE and ABSOLUTE measures Nominal pressures from 5 bar to 2500 bar AMPLIFIED outputs: 4-20mA, 10V or 5Volt Linearity and hysteresis 0,20% HIGH TEMPERATURE max. 150 ° C
Pressure transmitters of these series have been developed to extend to high temperature (150°) the well-known and appreciated features of TP3 transmitters.
The sensitive part, in contact with pressure, is entirely made of 17-4 PH corrosion-proof stainless steel.
High vacuum thermal treatments which stainless steel is subjected to, ensure the correct functioning even when highly dynamic stresses are involved. Monolithic execution of measuring element, without any assembling via tight rings or gaskets, guarantees a high long-term stability, with negligible hysteresis and zero drift. Pressure is internally detected by a full bridge strain gauge, which assures the maintenance of performances even in presence of peaks.
Electronic section, realised via SMD technology, consists of a high precision instrumental amplifier and a stable supplier,
protected against short circuits and polarity inversion.
Every pressure transmitters is entirely LASER welded and completely resin-encapsulated, to ensure insensitivity and a high degree of hermetic tight.
During production cycle, pressure transducers are thermally compensated, tested and individually calibrated with the use of completely automated stations that analyse and record data.
These features make them suitable for being used in several industrial fields, as : pneumatic, hydraulic, food process control, level and refrigerating (depression) plants. They are also installed on test benches, materials testing machines, laboratories and research in general.
