WEBENCH® SensorAFE Designer & WEBENCH® Sensor Designer Tools

WEBENCH SensorAFE Designer and WEBENCH Sensor Designer tools provide complete sensor circuit design for common sensing, transmitter, and transducer applications. You can start with an industry standard sensor or specify your own sensor requirements to create your own custom sensor. WEBENCH sensor tools provide you with optimized signal path performance, bill of materials, budgetary cost, and links to evaluation boards and other tools for testing and validating your simulated solution.

WEBENCH SensorAFE Designer and WEBENCH Sensor Designer include technical specifications for hundreds of temperature, pressure and chemical sensors including products from Omega Engineering, Honeywell Sensing & Control, Tempco Electric Heater, All Sensors, and more.

These sensor solutions fit a variety of different applications including

  • industrial process control,
  • factory automation, monitoring,
  • medical instrumentation,
  • drug delivery systems,
 
  • high temperature furnace monitoring,
  • weigh systems,
  • barcode scanners, and
  • HVAC systems.

WEBENCH Sensor Designer

For discrete (sensor + amplifier + ADC) circuit designs

The WEBENCH Sensor Designer tool provides a complete sensor to digital serial output solution. Your design will include a sensor interface, excitation source, precision amplifier, and an analog filter. This is followed by a serial-output, ADC that has a resolution between 8- and 16-bits. The WEBENCH Sensor Designer software makes it easy to design and optimize your sensor path. Just click the sensor type that you are interested in below to start your design.

Example schematic: Bridge sensor output is amplified by a 3-amp instrumentation-style amplifier. The amplifier circuit is driving a single-ended ADC.

How to use this design tool:

1. Explore & Learn
Click the blue Start Design button for your desired sensor type and choose a pre-loaded sensor, or enter a custom sensor to meet your needs. Then click the 'Create Design' button.

2. Compare & Select
Review the resulting schematic, bill of materials, performance summary, and other technical results in the Design Summary overview. Click on any of the displayed panels to review more advanced or detailed information behind each panel. You can modify design parameters or further optimize your design by selecting a different sensor, amplifier, ADC, or other system parameters.

3. Design & Build
Print a report to document your design or order evaluation kits, and other tools in the Documentation panel. You can then program your sensor board using the SPUSI2 Data Capture Board and Software.
