Strain Gauge or Load Cell Digitiser Module (DSC)

The DSC Digital Load Cell or Strain Gauge Digitiser Module is designed for use with strain gauge sensors such as pressure transducers, load cells and torque sensors, the DSC offers high speed, high precision strain gage signal conversion capabilities with linearization and temperature compensation of the sensor .

Available output formats include RS232, RS485 ASCII, Modbus, MantraCAN (J1939).

Please Note: MantraCAN products will only work with Mantracourt software up to and including Windows Vista.

For mounting internal to the sensor, the same electronics is also available in a compact miniature format – see modelDCell.

For mounting in a convenient IP65 enclosure, or for multiple load cell installations, refer to models DSJ1 Strain Gauge or Load Cell Digitiser Module (1Channel) and DSJ4 Strain Gauge or Load Cell Digitiser Module (4 Channel).

The Benefits to the Transducer User/System Supplier    
Mantracourt has identified the following points which demonstrate how strain gauge transducers users will benefit.
1. Plug-in-and-go-sensor
No need for a separate instrument, DSC provides a direct output in engineering units from a standard Strain Gauge, – save cost and space.
2. Simple to use
The Strain Gauge manufacturer can supply the sensor pre-calibrated for system offset, gain, hysteresis and scale parameters.
3. Outstanding performance to cost ratio
19 bit (500,000 divisions) and 0.001% noise immunity ideal for high precision process weighing applications such as batching, at a fraction of the cost of many instrument solutions
4. Low cost of Strain Gauge ownership
Use with low cost 2 pair twisted cabling – reduce set-up costs.
• Digital storage of calibration details, means the system will not need regular re-calibration – save maintenance costs.
• In-service replacement of a faulty/damaged Strain Gauge is possible by simply down loading the stored calibration details to a new cell. Save maintenance time and cost by not having to empty a vessel and re-apply test weights.
5. Universal systems compatibility
Fieldbus connectivity ensures interoperability with existing/future process control equipment
6. Non-expert maintenance
Self diagnostics alerts user to common Strain Gauge faults such as over-range.
