Page 3: About The Transducer
ABOUT THE TRANSDUCER transducer The ST-100 series of transducers operates in association with Milltronics ultrasonic level monitoring products. transducer The transducer converts the electrical energy of face the transmit pulse from the transceiver into acoustical energy. It then converts the acoustical –3 db... -

Refer to the associated transceiver manual. Do not overtighten mounting. Hand tightening of the mounting hardware is sufficient. On liquid applications, the transducer must be mounted so that the axis of transmission is perpendicular to the liquid surface.
