Tube-11 Ultra High-Temperature Vibrating Rod Level Switch is featured with the function of water cooling (air cooling) and is able to work reliably under ultra-high temperature conditions that up to 400℃ (482°F).
The operating principle is completely the same as that of the standard Tube-11 model. In terms of the structure, high-temperature model is assembled an extension tube between the housing and the process connection, so that the temperature in the housing can be reduced to a normal range where the electronic devices can tolerant. At the same time, all piezoelectric components that drive and detect the vibration are selected from high-temperature resistant piezoelectric ceramics, electrodes, wires, and encapsulant materials. These high-temperature designs ensure the instrument work reliably in process temperature conditions up to 400 ℃.
● High temperature resistant design with double vibration elements, process temperature up to 400 ℃ (482°F).
● The innovative developed technology enables the sensor to detect fine-grained solids with density as low as 0.02 g/cm³.
● Excellent in the precipitates interface measurement of liquids.
● An industry leading product that can tolerate high process temperature up to 400℃ (Water/air cooling).
● Strong self-diagnostic function helps to accurately locate the fault.
● Simple installation and maintenance free.
● With CE certificates, gas/dust Flameproof Enclosure and gas/dust Intrinsic Safety certificates, and IP66/IP67 Ingress Protection.
● Made of strong corrosion resistant material 316L.

Note： ① Maximum applicable particle size is 20mm, in this case, medium density must be lower than 0.05g/cm³.
② Cover exhaust nozzle with whistle from instrument accessories and position the whistle such that whistle’s internal wall at its vent side is tightly attached to the external wall of exhaust nozzle, slowly increase the flow of cooling air until whistle blows up. This is when cooling air is at the expected minimum flow.
● Level measurement of fine-grained solids with density as low as 0.02 g/cm³ in the process temperature up to 400 ℃ (482°F).
● Precipitates interface measurement of liquids in the process temperature up to 400 ℃ (482°F).
