Today, I will introduce a national invention authorized patent-a sanitary intelligent temperature transmitter. The patent was applied for by Jiangsu Yokogawa Group Co., Ltd., and the authorization was announced on January 25, 2017.

The utility model belongs to the field of production and manufacturing, and particularly relates to a sanitary intelligent temperature transmitter.

The temperature transmitter adopts thermocouple and thermal resistance as the temperature measuring element, and the output signal from the temperature measuring element is sent to the transmitter module, after voltage stabilization filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse After circuit processing such as protection, it is converted into a 4-20mA current signal output with a linear relationship with temperature.

Existing temperature transmitters have a small applicable range and can only be selected according to the pressure range that needs to be measured. When purchasing, different pressure transmitters must be selected according to different measurement ranges. The process will also cause a lot of inconvenience to the construction personnel; at the same time, in the actual work process, once the internal heat cannot be dissipated in time, it will cause the internal electrical components to fail and stop working, and it may even be serious. Causes the burning of vitality parts, so the existing temperature transmitter needs to be improved.

In order to overcome the above shortcomings, the purpose of the present utility model is to provide a sanitary intelligent temperature transmitter, which has a simple structure and reasonable design, so that the range can be adjusted.

In order to achieve the above objective, the present invention provides a sanitary intelligent temperature transmitter, including: a junction box, a temperature sensor, a clamp flange, a protective tube, a protective shell, and a control device, wherein the junction box is It is provided with a display device and an adjustment area, the temperature sensor is arranged on the upper part of the junction box, the clamp flange is arranged between the junction box and the protective tube, and the protective shell is wrapped in the junction box and the clamp method On the outside of the blue and the protective tube, the temperature sensor, the display device and the adjustment area are all connected with the control device.

The control device is provided with a sensing control module, a signal processing module, a display control module, and a controller module, and the sensing control module is provided with a range adjustment unit, and the sensing element controls the input and output terminals of the module They are respectively connected with the temperature sensor output terminal and the input terminal of the signal processing module, the display control module is connected with the display device, and the induction control module, the signal processing module and the display control module are all connected with the controller module. The sanitary intelligent temperature transmitter described in the utility model allows the staff to adjust the range according to the range they need by setting the adjustment area and the range adjustment unit, which greatly improves the scope of application At the same time, it also solves the error-prone problem during the construction process, which is convenient for the construction staff to install; at the same time, a display device is also set on the shell, so that the detected value can be carried out through the display device in time The display makes it easy for the staff to read the data, thus providing users with a lot of convenience, so that it can better meet the needs of users.

The junction box of the present invention is provided with a connection port, and the connection port is convex, which can facilitate the installation of the connection box with the external parts. The connecting port is provided with a connecting piece, and the temperature transmitter is connected with an external part through the connecting piece, so as to provide the stability and sealing of the connection. The clamp flange and the protective tube are made of one-piece molding, which increases the strength of its work and prolongs its service life. The inner wall of the protective shell is provided with a shielding layer, and the outer side is provided with an anti-oxidation layer, which has a good protective effect and prolongs its service life. The protective shell is also provided with heat dissipation holes, which can dissipate the heat generated by the transmitter in time, avoid malfunctions due to overheating, and improve the safety of its use.

The utility model has the following beneficial effects: the hygienic intelligent temperature transmitter described in the utility model is equipped with an adjustment area and a range adjustment unit, so that the staff can realize the range according to the range they need. The adjustment greatly improves the scope of application, and at the same time, it solves the error-prone problem during the construction process, which is convenient for the construction staff to install; at the same time, a display device is also set on the shell to make it timely The detected value is displayed through the display device, which is convenient for the staff to read the data, which provides a lot of convenience to the user, so that it can better meet the needs of the user. In addition, the inner wall of the protective shell of the present invention is provided with a shielding layer, and the outer side is provided with an anti-oxidation layer, which has a good protective effect and prolongs its service life; at the same time, the protective shell is also provided with a heat sink The hole can dissipate the heat generated by the transmitter in time to avoid malfunction due to overheating and improve the safety of its use.
