Do multiplexed installations damage the sensor electronics?
No. The “filament effect” suggesting that sensor amplifiers fail like a light bulb from repeated switching on and off is a myth. Piezoelectric accelerometer amplifiers are high reliability, low power devices (typical draw is less than 100 mW. The transistors used are designed for long term use in switching applications—modern transistor technology is based upon the older TTL computers that performed billions of switching operations. Wilcoxon has extensively tested the piezofet® in excess of two million switching operations without failure.
