1. Terminal housing
2. Transducer element
3. Transducer insert
(See also chapter 10.4)
Extraction tool specification
Connection: BSP 1 1/2 internal
Max. pressure: 40 bar
Space required for:
50 mm transducers 1200 mm
160 mm trandsducer 1400 mm
Flange type
Terminal box, transducer element and insert are identical in both versions.
The ultrasonic pulse is produced by sound energy being transmitted, via the window, to/from the
liquid. The sound source is a piezoelectric crystal in the insert.
The insert, consisting of a spring and piezo crystal, can be removed from the transducer element
during operation. No draining is necessary as the transducer element remains in the pipe.
When exchanging the transducer insert everything must be kept extremely clean to avoid dirt
between crystal and window.
