TECHNICAL FIELD
[0001] The utility model relates to electrical equipment grounding technical field, concretely relates to a quick installation's transmitter grounding device. BACKGROUND
[0002] A pressure transmitter is a device used to measure the pressure of a fluid or gas, which converts the pressure into an electrical signal for monitoring, control or recording in a control system or display device. It usually consists of a sensor and an electronic converter. The sensor part is usually composed of a sensitive element such as a diaphragm, strain gauge or piezoelectric crystal, which can sense the change of external pressure. When subjected to pressure, the sensor produces corresponding mechanical deformation or electrical signal. The electronic converter is responsible for converting the mechanical deformation or electrical signal output by the sensor into standardized electrical signal, such as 4-20 milliampere or 0-10 volt. These electrical signals can be transmitted through cables to control room or other devices for monitoring, control or recording pressure value. Pressure transmitters are widely used in various industrial fields such as manufacturing, chemical industry, oil and gas, water treatment, medical equipment, etc. They provide a reliable method to measure and monitor the pressure in fluid or gas system and convert it into electrical signal that can be used for control and decision-making.
[0003] The existing pressure transmitter has grounding requirements in actual application process. Currently, grounding is generally achieved by using grounding screws. This method has the following disadvantages or deficiencies: first, the convenience is limited, as the use of grounding screws occupies the space of the transmitter, which will result in an increase in overall height; second, the economic cost is relatively high, as the use of grounding screws and grounding rings is relatively expensive; and third, the production efficiency is low, as the assembly in the workshop is mainly manual, which is time-consuming and labor-intensive, resulting in low production efficiency.
