220v screw rotary resistance material level is mainly used in modern industrial processes and warehousing sectors, powdery and granular materials used to open the container, make level monitoring or control. Resistance rotary level can be used to store instructions status within silos, hoppers and other containers of powder particle material density materials are generally applicable from 0.5 ~ 2.0t / m3. Each silo typically use two rotary type level indicators that indicate the highest and lowest material level material level. You can also use more than one material position indicator to indicate more than one material level. Threaded pipe that comes through, you can easily complete the installation from a silo outside. The main components are made of bare steel and aluminum components. Resistant to corrosion, pollution, moisture, dust and other characteristics of the food industry and high dust and other harsh environments can be used; the main technical parameters: leaf speed: 2.5 rev / min Medium Density:> 0.2g / cm3 ambient temperature: -10 ℃ - + 80 ℃ Uses: upper and lower measurement Measuring Media: powder and granular materials, medium density ≥0.2g / cm3 (large leaf) blade speed: 2.5 rev / min Sensitivity: five-speed adjustable (movement ) Power supply: 110 V AV, 220 V AC Power consumption: <3W output: switch signal contact capacity: 220V3A (AC) Ambient temperature: -10 ~ + 80 ℃ material temperature: -0 ~ + 80 ℃, -10 ~ + 300 ℃ (high temperature) Installation: flange mounting, G11 / 2 "straight pipe thread Weight: 1.5Kg ~ 2.5Kg when the location of the installation should be made to avoid the blade and the lower inlet feed silo dead zones, side-mounted for prevent the use of the material in the smashing hit, should be installed above the detection fender blades. When using extension shafts mounted vertically, you should install a protective sleeve or the location of the blades and shafts are not to suffer a direct hit hit material. should be more than adequate to measure distance and avoid entanglement flexible shaft. In order to avoid the infiltration of rainwater outdoor environment, should make and outlet side mounted vertically downwards and tighten the lid. If conditions when mounted vertically, can consider installing rain cover is mainly used in modern industrial production processes and warehousing sectors. powdery and granular materials used to open the container, make the material level monitoring or control.
