What is the best supply voltage for the strain gages sensors?

[answer] =>

It is mentioned on the calibration certificate you received with the sensor.
For sensors without any amplifier, the best common setting is 10V because that voltage is used to calibrate the load cell in the factory.
The maximum voltage allowed is 15V (350 ohms bridges) or 20V (700 Ohms bridges), depending on the model.

Remarks:
For some small models (eg 5932, 5962), it may be preferable to use a lower voltage (eg 5V) to limit the temperature rise of the sensor.
Some battery-operated signal conditioners use smaller voltages to save energy.

Technical note about limitation of load limiter realized with 2 load cells and 1 BRIDGEBOY.

[answer] =>

It is possible to connect 2 load-cells in parallel to a Bridge-Boy but in this case we cannot guarantee the positive safety.

Load limiter Bridge Boy has been designed for use with only ONE load cell in order to detect any problem on the load cell. For example, if a wire of only ONE load cell is cut, it is possible that the Bridge-Boy will not detect it.

For this reason, CE certificate is.in this case no more available.

That is why we recommend the following schematics if you need to have a load limitation on the sum of the load of 2 load-cells.

CE certification is then available.

Fatigue resistance of SENSY load cells and torque sensors.

[answer] =>

SENSY force transducers and static torque meters consist essentially of a metal body that deforms as a result of the application of mechanical stress.

This mechanical stress may not exceed the elastic limit of the material under penalty of damaging or destroying the sensor.

However, even for deformations below the elastic limit of the material, there is a deterioration of the test body if these stresses are applied repeatedly.

This deterioration, which is initially very small, can ultimately lead to sensor failure.

This fatigue resistance is characterized by a guaranteed number of cycles. It depends on the material, the stress rate (μm/m) and whether this constraint is uni- or bidirectional.

For SENSY steel sensors, the fatigue strength is as follows:

Caution: This is not valid for certain types of sensors for which the maximum stress is not located where the strain gauges are bonded.
(eg : membrane sensors).
