acam - Solutions in Time

Time - the most universal of all physical quantities -  offers fantastic possibilities to solve difficult measurement tasks elegantly. Nearly all physical units like position, weight, pressure and temperature can be captured by time measurement.


Based on digital TDC-technology (TDC = Time -to-Digital Converter), acam's products transfer the manifold potential of precise time measurement to consumer, automotive, industry and scientific applications and offer professional solutions for difficult measurement tasks.


Ultrasonic Flow Meter Electronics made easy with TDC-GP22

Discover the new TDC-GP22, an innovative converter for ultrasonic flow and heat meters. The new save first hit detection and the pulse width measurement for signal strength monitoring are amazing new features with respect to instrument quality. The extremely low- current consumption in combination with enhanced features and increased performance perfectly meets the future demands in that field of application.

PICOCAP Capacitance-to-Digital Converters

acam's PICOCAP product line of capacitance-to-digital converters convinces in many aspects - resolution (up to 18 bit or 23 aF rms@ 10pF), low power (low as a 2 µA operating), speed (up to 500 kHz), flexible capacitance range from 1 pF to 100 nF, and many more.

On top of that, a number of new features have been added, e.g. the internal reference capacitance to save external components or the newly added EEPROM for storing user calibration data. Further, improvements for the operation with humidity and MEMS sensors have been made. Opens internal link in current windowRead more
