Abstract

The invention discloses a balanced type water pressure sensor and a testing method of the balanced type water pressure sensor, wherein the balanced type water pressure sensor comprises an A sensing device, a B sensing device, a base and a slag settler; under the control of a water pressure tester, the A sensing device of the balanced type water pressure sensor is used for testing a main body water depth pressure of a part free from water level variation, and the main body water depth pressure is taken as a control value to exert a balance pressure on a B water pressure sensor by a balance pressure gauge of the B sensing device; the B water pressure sensor, under the balance of the control pressure in the B water pressure sensor, is used for detecting the rest water depth pressure of a part with water level variation; and the main body pressure is added with the rest pressure by the water pressure tester, to obtain the tested deep water pressure. The balanced type water pressure sensor disclosed by the invention, while widening the measurement range, improves the testing precision, and has the characteristics of being simple and compact in structure, easy to install and capable of displaying data in real time; and a new instrument apparatus is provided for testing the deep water pressure with high precision.

Description

technical field [0001] The invention relates to a sensor for measuring deep water pressure, in particular to a balanced water pressure sensor and a testing method thereof. Background technique [0002] At present, test devices such as piezometric tube devices and conventional water pressure sensors are usually used to test water pressure. These devices are either poorly equipped, bulky and have manual visual readings, or they can only test water pressure at relatively low water depths in order to ensure test accuracy, so their applications are limited. Contents of the invention [0003] Aiming at the deficiencies of existing water pressure testing devices and sensors, the present invention proposes a balanced water pressure sensor and a testing method thereof, which can test deep water pressure in a large range under the premise of meeting the requirements of high-precision testing. [0004] The present invention solves technical problem and adopts following technical sch...
