1、EWDAR Damped Rotation Level ControllerThere are still more that we can offer to youSincere services to clients: With the increasing competition in the market, instruments that are accurate in measuring and free of maintenance can help to improve the production efficiency of the factories. EWDAR leve

2、l control system is such a product that can substantially improve the product quality and work efficiency of your company. We are always available to supply standard products or provide tailor-made products in response to your requirement for various application of EWDAR level measuring products in

3、such industries as power, cement, engineering machinery, casting, chemical and food processing etc. In addition to the excellent measuring technology, EWDAR will always provide high-quality services to all clients. 1、 Applications and characteristics: EWDAR series damped rotation level control syste

4、m has wide applications in the modern industry production process and warehousing sector for level monitoring or control of the powder and grain substances in the open type vessels. With full new design concept introduced in the product and many years of successful experiences, EWDAR series damped r

5、otation level control system features extreme low failure and unanimous positive comments from the clients of all walks of life. EWDAR series damped rotation type level control system features advanced technology, reasonable structure, reliable performance, easy and convenient use and maintenance as

6、 well as high cost performance etc; Compared with similar products in the market, EWDAR level control system has the following unique characteristics: 1) All major exposed parts and components use such materials as stainless steel, aluminum alloy or high-grade engineering plastic featuring such outs

7、tanding advantages as dust-proof, moisture resistance, corrosion resistance and no pollution to environment. EWDAR may be used in severe working environment in such industries as power, cement, casting, concrete, asphalt mixing equipments, food processing, grain warehousing and industries with high

8、produce of dust etc; 2) The output shaft is equipped with overload protection device, which can effectively avoid damages to the motors and speed reducers due to improper use or abnormal external force; 3) In order to make the equipment suitable for different materials with different specific gravit

9、y and also for purpose of easy installation and adjusting, the equipment is provided sensitive five-gear adjusting device and two installation options as well as many monitoring vane specifications; 4) ZXKHB type level control system is equipped with overheat protection device, which can ensure prop

10、er and normal working of the level control at temperature of 300 and below. (This ability is out of reach of some capacitor type, pitchfork type and ultrasonic type level monitors); 2、 Working principle: The working principle of EWDAR series damped rotation type level controller is described as foll

11、owing: Use of AC micro motor with speed reduction to drive the monitoring vane rotate at slow speed; when the level of the materials rises till the rotation of the vanes is blocked, the testing mechanism will have rotation displacement around the main shaft; this displacement will first put one micr

12、o switch in action to send signal that material is fed inside; and then the other micro switch will act to disconnect the power supply to the micro motor to stop the motor; as long as the level in the silo or container remains unchanged, this work status will be always maintained; When the material

13、level decreases till the vanes are tested with no blockage, the testing mechanism will restore to the original state due to pull force of the spring. First one micro switch will act to switch on the power supply to the motor to make the motor run, then the other micro switch will act will send signa

14、l that material is in shortage; as long as the rotation of the vanes will not be blocked by the materials, this work status will be always maintained. 3、 Outline dimensions: 1) Outline dimensions ( Figure 1) 2) Outline dimensions (Figure 2): 4、 Main technical specification: Product series ZXKNT1000
