The JX3-DMS2 strainometer module is a new periphery module from Jetter AG, the controller supplier from Ludwigsburg. It is connected either directly to the JetControl-3xx controllers or a JX3 bus head. The module has two differential short-circuit proof inputs with the following properties:
- Signal range: 1 mV/V to 400 mV/V
- 16-bit resolution plus oversampling
- Signal amplification: 0.5..1050
- Conversion time per 2 channels: 5..7 ms
- Maximum current per channel: 100 mA
The measuring accuracy and speed can be programmed with the software. Strain gauges can be connected to the two inputs. They work in accordance with the principle "Strain-resistance effect of electrical conductors". Typical applications are force measurement, strain measurement, pressure measurement as well as the measurement of mechanical stress. In addition the module features useful additional functions which make life easier for programmers such as a slave pointer, user scaling, oscilloscope function, forcing and limit value monitoring.
