Locomotive oil pressure transmitter assembly

The utility model belongs to the technical field of pressure transmitters, and particularly relates to a locomotive engine oil pressure transmitter assembly, which comprises a shell, a PCB (printed circuit board), a display screen and a locomotive air pipe, an internal thread connecting end is mounted on the locomotive air pipe, an external thread connecting end is mounted at the bottom of the shell, and a detection assembly is mounted inside the external thread connecting end; the protective cap is pushed by wind pressure to move and extrude the pressure sensor so as to detect the wind pressure of the machine tool wind pipe, the dustproof cap blocks the pressure relief hole to prevent dust from entering, meanwhile, dustproof protection is performed on the pressure sensor, and the dustproof cap is pushed by the wind pressure to move upwards to open the pressure relief hole to relieve pressure. Damage to the pressure sensor caused by overlarge air pressure is avoided, and meanwhile adsorption of accumulated wa
