Transducers
TRANSDUCERS WITH STRAIN GAUGES
We produce transducers according to customer requirements.
- Our transducers are suitable for measuring forces, mass, pressure, torque, acceleration
- Accuracy of transducers (non-linearity + hysteresis) with semiconductor strain gauges is the guaranteed to ± 0.5% of the nominal range or better
- Safe overload of our transducers is to 200% nominal range
- We can use foil strain gauges from other company in transducers
TYPICAL CHARACTERISTICS OF OUR TRANSDUCERS:
| UNIT | VALUE | |
|---|---|---|
| Input current | mA | 10 – 30 |
| Rated unloaded signal (the difference between output signal of 100% loaded and free sensor) at power Iin=10mA | mV | 50 ± 0.2 |
| Output signal of free sensor at power Iin=10mA | mV | 0 ± 0.2 |
| Output signal of loaded sensor at the nominal value at input current 10mA | mV | 50 ± 0.2 |
| Combining error (non-linearity + hysteresis) – in % of the nominal range sensor | % | < ±0.5 |
| Safe overload | % | 200 |
| Long-term stability (in% of the nominal sensor range) | % | < ±0.1 |
| Temperature coefficient of unloaded sensor signal | %/°C | <0.01 |
| Temperature coefficient of the output signal | %/°C | <0.03 |
| Operating temperature range | °C | -10 až + 40 |
| Life in terms of number of cycles of the nominal load | > 107 |
