The hygienic pressure transmitter is a pressure measurement device specially designed to meet the requirements of strictly hygienic environments.
It uses processes such as diffusion or ion implantation to form resistors on the pressure-sensitive diaphragm and connects them into a Wheatstone bridge. When pressure acts on the diaphragm, the resistance value changes, generating a linearized output signal proportional to the applied pressure. Then, through the secondary conversion circuit, signal forms such as two-wire 4-20mA output are achieved.
