Abstract
The utility model discloses a force-measuring parallel beam sensor which comprises a sensor main body, wherein two through grooves are formed in the sensor main body, and an overload-resisting groove is formed between the two through grooves. The utility model can resist the pollution of dust to the sensor, and even if the dust falls on the through groove, the service performance of the sensor is not influenced; when the sensor is overloaded, two surfaces of the overload resisting groove are attached together, so that the overload protection effect is achieved, and the sensor is protected from being damaged.
Description
Technical Field
The utility model relates to the technical field of sensors, in particular to a force-measuring parallel beam sensor.
Background
