Smart ultrasonic sensors have long range
Long range ultrasonic sensors use the latest microprocessor technology to provide low cost precision non-contact distance measurement for factory automation.
The MassaSonic M-300/150 and M-300/95 smart ultrasonic sensors offer longer ranges The M-300/150 detection range is up to 2.5m and the M-300/95 is up to 4.5m.
Vydas International Marketing said that the sensors complement the established M-300/210, which has a range approximately from 100mm up 1.3m maximum.
Manufactured by Massa Products Corp in the USA, the M-300 ultrasonic sensor design uses the latest ultrasonic and microprocessor technology to provide low cost precision non-contact distance measurement for factory automation or industrial process control.
