WEBENCH Pressure Sensor Designer provides complete circuit solutions for common pressure sensors or pressure transducer applications. The types of sensors covered are: bridge pressure sensors, load cells, strain gauges, and pressure transducers. Start by selecting a pressure sensor from a list of market leaders, or specify your own pressure sensor parameters by creating a custom sensor. WEBENCH Pressure Sensor Designer provides 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.
Pressure sensor solutions are used in many different applications industrial process control, factory automation, monitoring, calibration, medical instrumentation, drug delivery systems, weigh systems, compressors, refrigeration, hydraulics, power generation, fluid management, and HVAC systems.
WEBENCH Pressure Sensor Designer provides a complete pressure sensor to digital serial output solution, including sensor interface, excitation source, precision amplifier and filter, and 8-bit through 16-bit ADCs, and a serialized output to connect to various back-end systems.

WEBENCH Pressure Sensor Designer Solutions
WEBENCH Pressure Sensor Designer solutions are based on a 3-op amp instrumentation amplifier circuit, which detects the sensor voltage, amplifies it, provides simple filtering, and delivers it to an ADC. The sensor excitation is a voltage or current source, depending on how the sensor is specified. The ADC may have a single-ended input, if it is 8 to 12 bits, or differential input, for resolutions as high as 16 bits.
Standard pressure sensor products can be selected from a list, or a custom sensor can be "created" for use with the Designer.
Example schematic: Photodiode output current is converted to a voltage using a transimpedance amplifier. The amplifier circuit is driving a single-ended ADC.
