ZN338 seriespressure transmitterAdopting imported ceramic sensors and pressure transmitters with internationally advanced technology Combined with high-precision electronic components, it is assembled through strict process requirements. It is compared to the conventional pressure transmitters currently in use. There are two significant technological differences: one is the use of emerging high-precision ceramic materials for measuring components; The second is that there is no intermediate liquid inside the measuring element, and it is completely solid.
● Main features
pressure transmitterStrong overload and impact resistance, overvoltage can reach several times the measuring range, and even hitting the measuring element directly with a hard object does not cause damage, and has no impact on measurement accuracy; Pressure transmission The device has high stability, exceeding 0.1% of full range annually, and this technical indicator has reached the level of intelligent pressure instruments; The temperature drift is small, and due to the elimination of the intermediate liquid in the pressure measuring element, the sensor not only achieves high measurement accuracy, but is also minimally affected by temperature gradients; Wide applicability, easy installation and maintenance, pressure transmitter can be installed at any position.
