Description

Data acquisition brought to the sensor instead of the sensor to the rack: 3 universal bridge channels in an aluminium block machined from solid, sealed and rated IP67 from -40 to +85 °C. Each channel takes a full, half or quarter bridge — completion for 120 Ω and 350 Ω is built in, and so is the 100 kΩ shunt for the calibration check — or a voltage in the ranges ±10 V · ±1 V · ±100 mV · ±10 mV, digitised with 24 bit at up to 20 kS/s per channel. One hybrid cable carries data, power and synchronisation: EtherCAT at 100 Mbit/s, up to 100 m to the next unit, up to 64 units in a chain, all sampled to within less than one sample of each other. TEDS is read automatically, and DSI adapters extend the same channel to IEPE, thermocouple, RTD, LVDT and charge.

Measurement

  • 3 universal channels: full, half or quarter bridge, or voltage
  • 24-bit oversampled SAR with 41 kHz anti-aliasing filter
