Pressure transmitter applied to trolley

Abstract

The invention discloses a pressure transmitter applied to a trolley. The pressure transmitter comprises a transmitter body, a liquid inlet is vertically inserted and fixed in the middle of the lower part of the transmitter body, a cooling bin is horizontally arranged at the liquid inlet, a bent pipe is vertically arranged in the middle of the interior of the cooling bin, a partition plate is vertically welded in the middle of the interior of the cooling bin, the bent pipe is welded in the partition plate in a sealed mode, the two sides of the bent pipe are exposed, the partition plate divides the inner portion of the cooling bin into two cavities, a first connecting pipe is perpendicularly inserted in the middle of the lower portion of the cooling bin, liquid storage bins are welded to the positions, located on the two sides of the first connecting pipe, of the lower portion of the cooling bin, circulating liquid changing mechanisms are arranged in the liquid storage bins, and the lower end of the first connecting pipe is provided with a filter assembly. According to the invention, liquid to be detected is effectively cooled before entering the transformer body through circulating liquid change, so that continuous detection of the transformer body is ensured not to be affected, the service life is prolonged, and impurities are prevented from entering the transmitter body to affect detection data.

Description

technical field [0001] The invention relates to the technical field of pressure transmitters, in particular to a pressure transmitter applied to a trolley. Background technique [0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal for supply Indicator alarm, recorder, regulator and other secondary instruments for measurement, indication and process adjustment. Pressure transmitter is the most commonly used sensor in industrial practice. It is widely used in various industrial automatic control environments, involving water conservancy Hydropower, railway transportation, intelligent building, production automatic control, aerospace, military industry, petrochemical, oil well, electric power, ship, machine tool, pipeline and many other industries, includi...

AI Technical Summary

Problems solved by technology

[0003] When the commonly used pressure transmitter is used, it does not have the function of pre-cooling the liquid to be tested. If the temperature of the liquid to be tested is too high, the test result data will be inaccurate, and the impurities in the liquid to be tested will enter the pressure transmitter. The liquid needs to be pre-filtered. If it is not filtered, the measurement accuracy of the pressure transmitter will be low and the service life will be affected. Therefore, the pressure transmitter applied to the trolley is now proposed.
