Pressure transmitters for RELATIVE, ABSOLUTE and VACUUM measures Nominal pressures from 100 mbar to 2000 bar AMPLIFIED outputs: 4-20mA, 10V or 5Volt TP14 Linearity and hysteresis 0,10% LabTP14 Linearity and hysteresis 0,05%
Pressure transmitters belonging to TP14 series distinguish themselves for high precision, stability and long-term reliability of metrological features.
Main applications are found in industrial and automation fields, but, in particular, they are used as transfer sample or first line samples in metrological, research and development laboratories.
At the end of production cycle, when final tests are performed, two different accuracy classes are found: 0.10% standard and 0.05% LAB versions.
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 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.
