Description
Pressure transducers for RELATIVE and ABSOLUTE measures Nominal pressures from 10 bar to 700 bar Linearity and hysteresis 0,20% TP1 standard output 2mV/V TP1A amplified ouput 0,5-5,5 Volt
Pressure transducers belonging to TP1 series distinguish themselves for both high reliability, robustness and low price, obtained by minimising production costs with the use of new technologies as robotized stations and a diffuse use of LASER.
TP1 is manufactured in two versions, the non-amplified one with 2mV/V standard output and the amplified one with a 5V output which makes the connection to a PLC or to more advanced acquisition systems easier.
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.
Every pressure transducer 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.
