Abstract
In a load detecting device, a hermetically sealed sensor chamber is constituted by a sensor head, a bellows, a housing and a stem. A sensor chip for detecting pressure is housed in the sensor chamber that is filled up with liquid. When load is applied to the sensor head, the bellows contracts axially to vary pressure of the liquid. The sensor chip senses the pressure of the liquid so that the load applied to the sensor chamber is detected with higher detecting accuracy.
