Description
Description
On-line water analysis often places heavy demands on components of analyzer systems. This applies also to process liquid analytical sensors such as pH electrodes, conductivity sensors or sensors for dissolved oxygen and turbidity, which require a high availability in conjunction with low maintenance.
The ultrasound cleaning system manufactured by LFE for this purpose helps meet these requirements. The sensors mounted in a cross-flow vessel are irradiated at adjustable, regular intervals and defined duration by ultrasonic energy. The ultrasound generator creates cavitation bubbles in the water sample which serves as the coupling medium. The implosions of a tremendous number of micro cavitation bubbles results in the familiar excellent cleaning effect. The particles loosened from the sensors are carried away by the sample stream.
LFE's ultrasound cleaning system consists of the sensor vessel with the ultrasonic transducer and a separate control unit with the time controlled and remote controlled ultrasound generator. The control unit is housed in a water-protected (IP65) wall-mounted enclosure.
Features
- Cross-flow vessel made of PVDF (optionally PVDF) for up to 3 process liquid analytical sensors
- Ultrasonic irradiation - time controlled via timer or remote controlled via digital inputs
- Process water connections: G ½” female (other connections on request)
- High sensor service life
- High corrosion resistance of transducer membrane made of Hastelloy®
- Control unit housed in a water-protected, wall-mounted enclosure
