SI-RS485, Strain Gauge Sensor Interface


- High Accuracy
- Fast Measurement of up to 5000 Measurements/s
- Optional 2 Channel Type with 0.3…3 mV/V or +5 V Input
- Fail-safe by digital Interface
- Adjustment and Control Signal Switch via Software
- Adjusted values in EEPROM logged
- Long Input Lead from SI/RS485 to Evaluation possible
- Applicable in heavy Industries by robust Aluminum Casting Housing
connected via the standard interface and be queried individually. Voltage excitation of 10…30 V DC.
Factory-sided, the optional channel 2 can be configured as a strain gauge amplifier, or with +5 V input. This enables force and displacement measurement with the use of a potentiometric displacement sensor. The sensors are adjusted by software. Either by entry of the nominal values, by 2-point scaling through applying load or by the control signal switch (if available in the sensor).
These adjusted values are logged in an EEPROM, and remain there even after a power failure. Easiest system integration by short control commands for data exchange.
