Abstract

A mechanical electronic dual-display fluid monitoring switch device provided by the present invention comprises a device body and a trigger mechanism, and a left ejector rod, a strain beam, a right ejector rod, a first feeler lever, a strain resistor and a microswitch are arranged in the device body. One end of the left ejector rod is contacted with the trigger mechanism, the other end is connected with one end of the right ejector rod, and the other end of the right ejector rod is equipped with the first feeler lever. The first feeler lever is inserted in the microswitch and can be contacted with a contact on the microswitch, the left ejector rod or the right ejector rod penetrates the strain beam vertically, and the restrain resistor is electrically connected with an electronic display arranged on the device body. According to the present invention, by the combination of a strain beam fulcrum, the strain resistor and the microswitch, a novel fluid pressure or flow velocity switch monitoring device is formed, the mechanical electronic dual-display >fluid monitoring switch device can realize the fluid pressure or flow velocity switch and the electronic and mechanical pressure or flow velocity monitoring functions, is reliable to work, strong in function, and satisfy the demands of various occasions.

Description

technical field [0001] The invention relates to the technical field of a fluid monitoring switch device, in particular to a fluid pressure or flow rate monitoring switch device with mechanical and electronic dual displays. Background technique [0002] Today, pressure switches and flow rate monitoring of fluids have always been the focus of measurement in the industry. [0003] Current fluid pressure switches can be roughly divided into electronic pressure switches and mechanical pressure switches. Among them, the mechanical pressure switch relies on the elastic deformation and stroke of the pressure-sensitive element to convert the pressure into a switch signal, and the switch action can be completed without power supply. The commonly used elastic element is a coil spring, which pushes the piston to generate displacement through the pressure difference to complete the switching action. The electronic pressure switch needs power supply, the mv signal corresponding to the p...
