Product Overview
Signal Conditioner / Strain Gauge Amplifier with CAN Bus
The A2C-SG2 is a signal conditioner / strain gauge amplifier that measures mV inputs. It is the successor to the popular A2C-SG, improving upon the design. The A2C-SG2 offers complete IP67 ratings on all connectors. It can be used to interface strain gauge bridges or load cells directly. 2 channels are available to simultaneously measure the two inputs. A new special high speed mode is available for a single channel measurement with a data rate of 4800 samples per second.
The sensor communicates the measurement to a host via CAN Bus, using a standard M12 connector which is also used in J1939 networks. The A2C-SG2 contains a high performance 24-bit analogue to digital converter and a high performance DSP processor. It can be programmed / calibrated to output any kind of unit. Raw ADC values are also available. Alarms can be programmed to trigger when a given threshold limit is passed.
Features
More Than a Simple Strain Gauge Amplifier
By using a high performance DSP, the A2C-SG2 goes beyond simple signal conditioning. Each channel can be calibrated to a preferred unit of measurement. For a load cell this could be kg / tonnes / kN or any other value. For a strain measurement this could be micro strain or MPa. These measurements can then be requested as:
- Normal value
- RMS value
- Minimum value since last reset or last data request
- Maximum value since last reset or last data request
Additional Capabilities
- Programmable data rate from mHz to 4800 Hz
- Programmable alarms for both channels
- Heartbeat CAN messages with programmable periods
- Periodic CAN messages with programmable data and time periods
- Logic alarm output for standalone mode without the use of CAN Bus (request special version)
- Low power consumption
- Durable aluminium / stainless steel housings
- Software upgradable via CAN Bus
