Embodiment Construction

[0018] The present invention will be described below in conjunction with the accompanying drawings of the embodiments (taking chemical production line pressure detection as an example).

[0019] As shown in Figure 1, it is a very common pressure detection installation method in chemical production lines. The sensor 1 and the detected container (the detected end 3) are connected through a two-way safety valve 2. There are many shortcomings in this method, mainly reflected in the cumbersome maintenance and adjustment procedures and heavy workload, which is not conducive to making full use of advanced equipment.

[0020] Taking pressure zero point adjustment as an example, the following steps must be followed: 1) Close the safety valve; 2) Disassemble the sensor; 3) Make the sensor conduct with the zero pressure environment (atmosphere or special environment); 4) Zero point adjustment; 5) ) Installation test; 6) Repeated adjustment according to the aforementioned process.

Abstract

The invention discloses an installation method of a sensor multipath structure, which is characterized in that after the sensor is connected with an end to be detected, the invention has at least one path at an idle end that can be selected, and the path at the idle end can be one or more than one paths, which provides convenience for implementing the zero adjustment and calibration of the sensor, cleaning devices, adding medium, simulating experiments, etc. maintenance works and transforming detection environments, and the sensor does not need to be detached repeatedly. The invention does not affect the sensor structure and functions, provides convenience to the daily maintenance, adjustment and calibration of the sensor, ensures security performance and has great commonality. The invention can be taken as a novel sensor structure in sensor production, as well as a novel installation method of a common sensor in loop detection.

Description

technical field [0001] The invention belongs to a sensor installation method. Background technique [0002] With the advancement of science and technology, sensors are more and more widely used in industrial production lines, equipment, and products, and they have shown a pivotal position. The vast majority of sensors adopt a straight-through structure, which is connected to the measured environment through a simple pipeline (as shown in the figure). This connection method is very common, but there are many disadvantages. Sensors are precision instruments that receive and output signals through inductive elements. After a period of use, problems such as zero drift and accuracy degradation will inevitably occur. Therefore, the corresponding maintenance and adjustment work frequency is usually relatively high. The above-mentioned connection method only considers the needs of detection, but it creates a lot of trouble for daily maintenance and adjustment work-simple maintenanc...
