Description
Pressure transducers for RELATIVE, ABSOLUTE and VACUUM measures Nominal pressures from 10 bar to 1000 bar Output 2mV/V Linearity and hysteresis 0,50% PROTRUDING DIAPHRAGM HIGH TEMPERATURE max. 150 ° C
Pressure transducers belonging to TP8 series, born to solve problems in food industrial sectors, are now commonly used in those productive processes where pressure or level measurements of dense substances at high temperature (max.150°C) are required.
FLANGE standard coupling enables easy-to-perform mounting and cleaning of the sensor, to prevent from formation of residuals on the measuring diaphragm.
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.
