SAW Technology

Features & Benefits

Wireless	Enables measurements on moving and rotating parts Can be placed in confined and inaccessible places Avoids costly or impossible cabling Facilitates placement in harsh environments
Passive	Infinite autonomy No battery nor energy harvesting Small and light (e.g.: 5x5mm - 2g) Maintenance free Can be embedded into material
Robust & Stable	Operates in severe environments – strong electro-magnetic fields, high acceleration, high temperature, explosive, corrosive, radiated environments Hermetically sealed – e.g. performs even rotating in oil Maintenance (and re-calibration) free Calibration free for some applications Time stable (based on differential structure)
High performance	Large measurement range (low to high temperature and strain) Multi-functional sensor - e.g. pressure and temperature High frequency – e.g. 434, 868-915-950MHz or 2.45GHz High bandwidth – High sensitivity (e.g. +/- 0.15bar for a 10-bar pressure sensor) - High access data rate (e.g. 2kHz) Read-out distance of several meters (up to 15m) Advanced digital transceiver easily connectible to customer systems through standard interface Continuous interrogation and display
Green technology	No battery disposal No chemicals needed for maintenance No cable or wire disposal Low profile, miniature, non-invasive
Mature technology	Very mature technology - millions of filters are produced each day for mobile phones Low cost in volume manufacturing Small manufacturing dispersion (+/- 10ppm)
