• • • Overview of Product • • •
MS321C anti - corrosive liquid level transducer is a new liquid level - measuring series product specially measuring sea water level and viscous and corrosive liquid level using the state–of–the–art technology of German HELM. It adopts German HELM made titanium alloy large flat membrane sensor as well as advanced manufacturing and encapsulating technology, supported with high–accuracy electronic elements, to great enhance service life and comprehensive performance of the product. It adopts internationally state–of–the–art ceramic capacitor sensor and adopts dry pressure measuring technology with intermediate liquid, thick membrane electronic technology, surface mount technology (SMT) and PFM signal transferring technology to fully play a role of technical advantages for ceramic capacitor sensor, with strong anti–corrosive, anti–overloading, and anti–impact capacity, high stability, and very high accuracy of measurement. This series of product may widely used for such corrosive and viscous liquid level measurement and control field as sea water level etc.
• • • Features of Product • • •
1. Strong corrosive resistance;
2. Large flat membrane design and good clogging resistance;
3. Wide range of measurement, from micro pressure 0.5m to high pressure 200m;
4. Strong anti–overloading and anti–impact capacity, with over pressure up to several dozens times to several hundred times of scale;
5. Adoption of imported ceramic capacitor sensor, with strong signal output, high comprehensive accuracy, and good stability;
6. Small temperature drifting due to without intermediate liquid for measuring element
