Multi Transmitter 8-Zone
The SDT 8 Multi-setting is an adjustable (six positions) Ultrasonic Transmitter that is used in combination with an SDT Ultrasonic Detector.
This combination is an accurate and reliable tool for testing the tightness of every kind of object or volume. (Refer to the application notes on tightness testing for further information.
Eight sensors are laid out in the equipment in such a way that they transmit in the volume of a hemisphere. Each ultrasonic sensor is frequency and power stabilised. The transmission frequency is 39.2 and 39.6 kHz (bi-sonic mode) for a power of 125 mW.
The potentiometer defines the power of the ultrasonic signal; level 6 being the maximum level.
