Abstract

The present invention provides a corrosion-resisting all-metal pressure transmitter. The corrosion-resisting all-metal pressure transmitter comprises housing, a probe and a cable joint. The cable joint is installed from the upper portion of the housing, the cable joint is fixedly fastened to the inner wall of the housing through nuts, and the probe is connected with the housing; a plastic part is arranged in the housing, and the housing is provided with a circuit structure for controlling the working of the pressure transmitter; an internal screw thread blind hole 1 is arranged at the center position of the end portion of the probe, and the internal screw thread blind hole 1 is provided with a clamping ring; and steps are arranged at the bottom of the blind hole 1, an internal screw thread blind hole 2 is downward arranged at the center of the steps, and the internal screw thread blind hole 2 is provided with damping screws. Through adoption of an air vent and a damping screw structure, the corrosion-resisting all-metal pressure transmitter is able to unload pressure timely and improve the reliability of products when instant pressure is large; and moreover, the corrosion-resisting all-metal pressure transmitter matches an input keyboard to freely set different alarm points and output time-relay time according to the requirement of fields.

Description

technical field [0001] The invention relates to a transmitter, in particular to a corrosion-resistant all-metal pressure transmitter. Background technique [0002] The pressure transmitter is used in the pressure monitoring system. When the pressure in the system changes, a detection signal is generated, which is converted into a corresponding analog voltage and current signal through the signal processing module, or a corresponding alarm signal is output according to different alarm point settings. Pressure and protection systems for testing systems. However, ordinary pressure transmitters have a single output signal, are susceptible to external interference, and have low precision. Most of them are mainly potted as a whole, with complex processes, high costs, and inconvenient maintenance. Acid and alkali, corrosion, cannot be used in high temperature and high pressure environment, and the application field is limited. [0003] patent documents CN203657964U A pressure tr...
