Sonaphone Ex


The Sonaphone Ex is designed for the rapid, reliable and cost-effective detection of seal failures and the smallest of leaks within compressed air systems and networks, vacuum systems, industrial equipment and machinery and covered pipes with restricted access. The ultrasonic detection device enables the early detection and avoidance of potential damages and resulting cost savings.

The regular inspection of engines, pumps and gearing using the Sonaphone Ex leads to increased operational reliability and guarantees a higher degree of availability of machinery. By means of the flow noise the inspection of the leak tightness of valves, slide valves and steam traps is possible. The option of an additional ultrasonic transmitter allows the control of the leak tightness of windows, doors, cabins and devices with little additional expense.

Defect induced noises and wear to various machinery components and rotating machinery can be recorded electronically. In addition to all individual and serial testing procedures, all irregularities can be transferred to a PC online and presented and archived in graphic and tabular format.

An efficient integrated data logger enables the rapid transfer of data between the device and your computer via a USB interface.

The addition of an optional temperature sensor allows the measurement and simultaneous recording of surface temperatures of up to 800 °C. The SONAPHONE Ex has a user-friendly display and PC software with logical menu navigation.

Due to its intrinsically safe construction design, the SONAPHONE Ex is also suitable for use in areas with risk of explosion
