Description

A waterproof cover and pressure transmitter

Technical Field

The utility model relates to the connection field, in particular to a waterproof cover and a pressure transmitter.

Background Art

The pressure transmitter is mainly composed of three parts: a pressure sensor (also called a pressure sensor), a measuring circuit and a process connection. It can convert the physical pressure parameters of gas, liquid, etc. sensed by the pressure sensor into a standard electrical signal (such as 4-20mADC, etc.) to supply secondary instruments such as indicator alarms, recorders, and regulators for measurement, indication and process adjustment. The process connection was originally installed vertically on the transmitter cover; the transmitter was installed on the equipment pipeline. The transmitter was exposed to the outside at the site because the connection point was exposed to the outside. After a long period of wind, sun, and especially rain, the process connection will corrode; in severe cases, water will enter the transmitter from the connector, causing damage to the measurement circuit, affecting the measurement accuracy, and in severe cases shortening the service life of the transmitter.

Utility Model Content

DETAILED DESCRIPTION

The utility model will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

As shown in FIGS. 1 and 2 , the utility model provides a waterproof cover, comprising: a cover body 2 mounted on a transmitter body 1 , a mounting hole 5 is provided on a side of the cover body 2 , and a connector 4 for connecting to the transmitter is installed in the mounting hole 5 .

Preferably, a cavity 3 is provided in the cover body 2, and the cavity 3 is used to place the external wiring of the transmitter body 1. A groove 21 connected to the cavity 3 is provided on the side of the cover body 2, and the mounting hole 5 is provided in the groove 21. The connector 4 is snap-fitted and installed in the groove 21, and the external wiring of the transmitter body 1 is connected to the connector 4. In the utility model, the cover body 2 is a waterproof cover, and the connector 4 can be embedded in the waterproof cover to avoid water intrusion, making the product safer, more reliable and durable. Exemplarily, the groove 21 is a circular structure, and the connector 4 is sealed and fixedly installed in the groove 21 by screws.

In addition, the bottom of the cover body 2 in the present invention is fixedly mounted on the transmitter body 1 by screws 22, and the bottom of the cover body 2 is a step-shaped structure. The cover body 2 is fixedly mounted after being engaged with the transmitter body 1.

In the present invention, as shown in FIG. 3 , a pressure transmitter is further provided, comprising a transmitter body 1 , on which the above-mentioned waterproof cover is installed.

An O-ring 11 for sealing is arranged between the transmitter body 1 and the waterproof cover. This structure can further seal the transmitter body 1 and prevent water from entering the transmitter body 1.

In addition, it should be noted that the present invention can also be applied to other connection ends of the pressure transmitter and is not limited to the structure of the present invention.

The working process of the utility model is:

When the pressure transmitter needs to be connected, the connector is installed on the side of the cover body 2 and connected to the cable. The utility model sets the connection end on one side of the waterproof cover body, and the connector can be embedded in the cover body. While not affecting the connection effect, it reduces corrosion to the connector and extends the service life of the entire device.

It is obvious to those skilled in the art that the above-mentioned specific examples are only preferred schemes of the present invention. Therefore, the improvements and changes that may be made by those skilled in the art to certain parts of the present invention still embody the principles of the present invention and achieve the purpose of the present invention, and all belong to the scope of protection of the present invention.
