Description
Pressure transmitters for RELATIVE, ABSOLUTE and VACUUM measures Nominal pressures from 100 mbar to 2000 bar AMPLIFIED outputs: 4-20mA, 10V or 5Volt Linearity and hysteresis 0,50%
Pressure transmitters belonging to TP3 series distinguish themselves for high long-term reliability of mechanical and electrical features and for their low price, obtained by minimising production costs with the use of new technologies, robotized stations and a diffuse use of LASER.
Among the sectors where these transmitters are employed, some are worth being underlined: pneumatic, hydraulic, refrigerating and level plants. They are also used in test benches and in materials testing machines.
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 transmitter is entirely LASER welded and completely resin-encapsulated, to ensure insensitivity and a high degree of hermetic tight.
During production cycle, pressure transmitters are thermally compensated, tested and individually calibrated with the use of completely automated stations that analyse and record data.
