PICOSTRAIN® - Digital Weight Measurement Circuits for Strain Gages

PICOSTRAIN® circuit - on chip microprocessor for load cell weight measurement, offers high resolution to pico second, low current, and digital circuit integration without analog dependence.

Precise, Flexibile Digital Weight Measurement Solutions
PICOSTRAIN® circuits use the acam TDC measurement principle to measure resistance in conjuction with capacitance in time intervals instead of voltage. This enables strain-gage measuremment by a time to digital converter circuit.

 

Wheatstone Bridge - A Thing of the Past
Unlike a wheatstone bridge, the lean circuit design of PICOSTRAIN® is integrated. It does not require analog input and has flexible update rates. PICOSTRAIN® circuits operate well with a half-bridge, consuming ultra low current.

 

High Resolution - Digital Strain Gage Measurement
PICOSTRAIN® circuits easily handle wide temperature ranges and compensation. High Resolution strain-gage measurement with PICOSTRAIN® is so precise and efficient, that this technology sets new standards in circuit design.

PICOSTRAIN® - Circuit Features

  • No elaborate supply of the strain gage
  • Up to 90% power current savings over traditional ADC solutions
  • No need for a full-bridge, 2 resistors (half-bridge) are sufficient
  • Reduction of the current into the strain gage (total system current down to a few µA)
  • Easy temperature compensation and wide temperature range with high stability
  • No reference voltage
  • Flexibility in update rate, precision and current consumption
  • Wide temperature range up to process limits
  • Low current circuit, ideal for solar panel and green technology
  • CMOS circuit integration - digital advantage without analog input
  • Unique solution for software compensation of span and offset drift
  • RoHS Compliant Components
