Pressure transmitters to permanent IMMERSION for level measures Nominal RELATIVE pressures from 300mbar (3mH2O) to 20bar (200mH2O) AMPLIFIED output 4-20mA 2 wires Linearity and Hysteresis 0,10%
Pressure transducers belonging to TPL2C series have been designed to be used as immersion level measuring instruments, employable in manifold fields dealing with controlling, regulating and monitoring activities.
Installation of the sensors requires their total immersion (IP68 protection class) at maximum depth, where measurements to determine levels non-dense substances are performed from.
The sensitive part in contact with pressure, and the whole body as well, is entirely made of AISI 316L corrosion-proof stainless steel.
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.
