Jiwei Rotary Paddle Switch Successfully Applied to Hot-Melt Adhesive Granules Level Measurement

Hot-melt adhesive granule is a kind of translucent granule or powder with fineness about 40 to 80 meshes and very easy to seep into the internal space of the instrument. Because the rotary paddle level switch is with a rotary unit, the granules are very easy to penetrate through the gap around the rotary shaft and cause false signal or damage to the instrument. Therefore, the requirement for the sealing around the rotary shaft and the sealing of the whole instrument are key challenges for the design and manufacture of the instrument. Furthermore, dust Flameproof Enclosure explosion proof certification is a must because the hot-melt adhesive granules may drift in the air due to its fineness to become an explosion hazard.
