The invention discloses a pressure testing device for sensor production, and the device is provided with an electric push rod, a strip-shaped plate, a vertical plate, a rack, a first bevel gear, a second bevel gear, a rotating cylinder, a ratchet wheel, a bevel gear disc, and a carrying disc which are connected or engaged with each other, and can drive the carrying disc to rotate through the transmission of the above parts when the electric push rod drives a pressing plate to move upwards, so that one placing mechanism on the loading disc rotates along with the loading disc and is finally located under the pressing plate, a to-be-tested sensor can be placed on the placing mechanism when a previous sensor is subjected to pressure testing, namely, when the previous sensor is subjected to testing, a next to-be-tested sensor is installed and fixed, and waits for testing. Through the above arrangement, continuous testing of the sensors can be realized, testing of one sensor and installation and fixation of another sensor can be simultaneously carried out, and the fixed to-be-tested sensor can be rapidly transferred to a testing position for testing, so that the testing efficiency can be greatly improved.
