Preferably, the panel is made of stainless steel.
Preferably, the display screen comprises a screen and a display circuit board, the screen and the circuit board are respectively and electrically connected with the display circuit board, and the keys are arranged on the display circuit board.
Preferably, the panel has a through hole, and the key passes through the through hole to above the panel.
The utility model discloses a novel concealed micro differential pressure transmitter. According to the technical scheme, the functions of differential pressure detection, temperature detection, humidity detection and the like are integrated, pressure, temperature and humidity can be monitored simultaneously, three analog signals can be output, and one communication can be output. The product can be embedded into a wall for installation, and only a stainless steel wire drawing panel and a liquid crystal display screen are displayed outside. The pressure taking mode can take pressure through the panel holes, and the pressure taking mode can also be hidden through the hose, so that the on-site installation is flexible and convenient. The micro differential pressure can be calibrated at an online timing, and the problem of temperature drift of a small-range sensor is solved. The temperature and humidity are subjected to data acquisition through an external probe. As a novel indoor embedded multifunctional transmitter, the utility model does not increase the construction difficulty, and is simple and beautiful; the utility model applies the industrial level transmitter to the civil field, and the expansion of the application range is expected to increase the income of enterprises.
