Abstract
The present invention comprises a hydra-pneumatic load sensor and signal system including two stacked bellows, one filled with liquid, the other with a pressurized gas. Load on the sensor is initially supported by the gas filled bellows to a predetermined limit, above which the liquid filled bellows generates a liquid pressure signal which is used with a readout or control device.
