SI-USB3 - Applications

Typical Applications
- Mobile test measurements using a laptop
- Experimental setups in test laboratories
- Secondary measurements of control devices
- PC-based recordings of strain characteristics
- measurements in chemical & biotechnology industries

Many standard sensors, such as force-, torque-, displacement- and pressure sensors, linear potentiometers, temperature probes PT100 etc., can be used with the SI-USB3. The sensor parameters can be stored in the SI-USB3. After a single parameterization, each sensor is automatically recognized by the software.

The voltage supply of the SI-USB3 is provided by an external 110Vac adapter, or by a 10 to 30 Vdc Power Supply. The connected sensors are directly supplied with voltage through the measuring amplifier which eliminates the need for separate sensor supply voltage. The low-pass filter second order allows filtration of unwanted frequencies. Here you can distinguish between four cutoff frequencies.

The connection to LabVIEW or integration into own programs is possible with the available driver package.

If a control signal is integrated in the sensor, an automatic adjustment can be carried out and checked at any time (measuring chain monitoring).

The following Sensor output signals can be digitally converted and conveniently displayed and evaluated via the free evaluation software:
- Load, Torque, Strain or Pressure Input range ±3 mV/V (Excitation 4V ≤20 mA)
- Process Signal or Sensor Input range ±5V/±10V (Sensor supply 12V ≤80 mA)
- Process Transmitter or Sensor Input range 0/4 ... 20 mA (Sensor supply 12V ≤80 mA)
- Linear or Rotary Potentiometer Input range 0 ... 5V (Sensor supply 5V ≤170 mA)
- RTD - PT100 Input range -200 ... 860 °C (Sensor supply 4V ≤20 mA)
- Quadrature Encoder for speed /angle measurement Input range 5V TTL (Sensor supply 5V ≤85 mA)
