[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 sensed by a pressure measuring element sensor into a standard electric signal to supply secondary instruments such as indicating alarm instruments, recorders, and regulators for measurement, indication, and process adjustment.

Once an overpressure abnormality occurs, the detection box is prone to explode, resulting in casualties. At the same time, when the gas inside the detection box leaks, it cannot be detected in time, thus affecting the detection effect of the pressure test.

[0005] In view of the above problems, the present utility model document proposes a pressure transmitter pressure test detection device. Content of the Utility Model

[0012] In a possible design, the protection mechanism includes an air release pipe, a leakage detector, a warning light, a buzzer alarm, two explosion-proof frames, a plurality of connecting plates, multiple sets of fasteners, four fixing plates, and four sets of mounting bolts. Both of the two explosion-proof frames are arranged outside the detection box. A plurality of the connecting plates are respectively and fixedly arranged on the outer sides of the explosion-proof frames. The plurality of connecting plates are divided into multiple groups. Each group of the connecting plates is connected and fixed by each set of fasteners. The fasteners include connecting bolts and connecting nuts.

[0013] In a possible design, the four fixing plates are respectively and fixedly arranged on both sides of the two explosion-proof frames. Each fixing plate is fixedly installed on the detection table by each set of mounting bolts. A sealing gasket that is closely attached to the detection table is arranged on the bottom side of each explosion-proof frame. Rubber gaskets are arranged on one side where the two explosion-proof frames are close to each other.

Then, the booster pump is started to inject the pressure medium into the detection box until the preset detection pressure is reached. During this process, the two pressure sensors continuously monitor the pressure change in the detection box to ensure the accuracy of the detection data. If there is a leakage in the detection box or the pressure transmitter, the leaked gas will be discharged through the exhaust pipe and detected by the leakage detector. Once a leakage is detected, the leakage detector will immediately trigger the warning light to flash and the buzzer alarm to sound, reminding the operator to pay attention, so as to improve the warning and installation effect and enhance the safety protection. Finally, after the detection is completed, according to the data recorded by the pressure sensors, the performance of the pressure transmitter can be analyzed to see if it meets the requirements.

Subsequently, the next pressure transmitter to be detected is taken out from the feeding frame, and the above detection process is repeated for easy use.

[0020] In this utility model, the pressure transmitter pressure test and detection equipment can be fixed outside the detection box through the protection mechanism to ensure safety during the detection process, so as to achieve the later protection effect. At the same time, it can detect gas leakage and remind the operator to pay attention, enhancing the safety protection;
