3、 Core Performance and Functionality
Multimedia adaptationCan detect conductive/non-conductive liquids such as water, oil, acid-base solutions, as well as solids such as powders and particles, and is suitable for media in multiple industries.
Intelligent anti-interference: Automatically distinguish between media and adhesive, inhibit foam interference and reduce false alarm rate; Equipped with short circuit and reverse polarity protection, LED status indicates faults.
IO Link Intelligent CommunicationSupport remote setting of switch points, hysteresis, and output types, real-time diagnosis of equipment status, and simplified debugging and maintenance.
auto-calibrationOne click calibration, no need for complex operations, adapted to the characteristics of different media under different working conditions.
safety complianceCompliant with ATEX intrinsic safety explosion-proof (Ex i), WHG, EHEDG, 3A, UL and other standards, suitable for hazardous areas and food contact scenarios.
4、 Adaptation scenarios and installation methods
-
Typical Applications
Chemical industry: overflow alarm and dry operation protection for acid and alkali storage tanks and solvent tanks;
Food and pharmaceuticals: liquid level control of beverage and drug storage tanks, in compliance with hygiene standards;
Water treatment: liquid level monitoring of sewage tanks and clean water tanks to prevent pump idling;
Powder industry: Level detection of granular materials and powder silos to avoid full/empty storage.
-
Installation method
Thread installation: G1/2 thread, suitable for tank top/side wall installation, reliable sealing;
Electrode installation: Vertical/horizontal installation, away from metal structures, to avoid capacitor interference;
Electrical connection: M12 connector, easy to wire, IP67 protection.
5、 Key points for debugging and maintenance
debugging toolRemote configuration of switch points, hysteresis and other parameters through IO Link master station or JUMO software, supporting online monitoring.
Wiring specificationsSeparate the wiring of power and signal lines, and ground the shielded wire at one end to reduce electromagnetic interference.
calibration methodPerform automatic calibration in an empty tank state to adapt to different dielectric constants of the medium.
Maintenance RecommendationsRegularly clean the electrodes (high viscosity medium), check the cables and seals to ensure the protection level.
6、 Selection and Alternative Reference
If longer electrodes are required, the same series with long electrode models can be selected; If higher pressure is required (such as 600 bar), the MAERA series static pressure level switch can be replaced.
When replacing traditional float switches, there is no need to consider medium density, installation is more flexible, and maintenance costs are lower.
