damped Level Switch

UZK series damped Level Switch is suitable to control the level in the open container in the industry process. When the level reach the upper limit or lower limit, the controller will output relay contact alarm or control signal. The controller includes explosion-proof type(explosion-proof mark is d Ⅱ BT4) and non-explosion-proof type. The structure of controller is simple and easy to maintain. It is an ideal level control instrument.

principle

The anti-rotation level switch  produced by Shanghai Automation Instrumentation Co., Ltd. is the use of micro-motor drive device, the drive shaft and the clutch connected to the material when the contact, the normal operation of the motor, when the blade contact material, the motor stops rotating, The device outputs a contact signal and turns off the power supply to stop turning. When the material falls, the resistance of the blade disappears and the detection device relies on the torsion spring to return to its original state. For different proportion of material torque can be adjusted.

Features

1, can be a long time continuous operation;

2, a unique oil seal design to prevent dust from penetrating along the axis;

3, torque stability and reliable, and the size of the torque can be adjusted;

4, leaves bear heavy load, the motor rotation mechanism will automatically slip, protection from damage;

5, continue to specifications, leaves, length can accept custom.

parameter

Power supply: (A) 110VAC (B) 220VAC (C) 12VAC (D) 24VDC

Contact capacity: 5A / 250VAC SPDT

Withstanding voltage: 1500VAC × 1min Blade speed: 1rpm

Protection class: IP65 entry port Specifications: 1/2 "PF

Applicable minimum weight: 0.3g / cm3

Temperature: -20 ~ 80 ℃ (high temperature resistant to 400 ℃)

Technical advantages

Rotary control on / off - without bolts, motor auto-off design and double seal bearings extended via UL, CSA, ATEX / IECex certification, rotary control, The life of the anti-rotation switch. The anti-rotation switch maintenance costs are relatively low, explosion-proof, high temperature to 399 ℃.

application

The pull-type level switch is used to detect the height of the solid material (powder, particle) level

Site control equipment, its unique seal design, superior overload protection and easy installation, it is widely used in feed, food, pharmaceutical, chemical, plastics, construction, fertilizer and other industries.

Installation Precautions

As shown in Figure 1, make sure that the power supply voltage is consistent with the voltage above the label before installation.

2, anti-rotation level switch should be avoided in the feed port, when can not be avoided when the installation of protective baffle to protect the blade from the impact of materials.

3, the level of installation, the junction box into the line should be vertical down, the cable fixed nut must be locked, if conditions can be added rain cover and so on.

As shown in Figure 4, before the installation to confirm the level of installation or vertical installation.

5, the level of the installation of the blade with the horizontal downward 10 ~ 20 ° angle to install, to reduce the impact of materials.
