Installation Guidelines of Ultra-High Temperature Vibrating Rod Level Switch

Product catalog summary

Introduction
Shenzhen Jiwei Automations Ltd. has developed the Tube-11 Ultra-High Temperature Vibrating Rod Level Switch, designed for environments with process temperatures exceeding 250℃, and capable of operating reliably up to 400℃. This is achieved through an innovative cooling sleeve pipe that uses air or water to maintain the internal components at safe operating temperatures.

Specifications and Features
The Tube-11 model includes a cooling sleeve pipe welded to the process connection, allowing air or water to flow through a capillary copper tube to dissipate heat. This design ensures reliable operation in ultra-high temperature conditions, expanding its application range.

Installation Guidelines

Air/Water Intake Tube: Use a standard 6*4mm PU air tube, ensuring a flat cut at the end for secure connection. The recommended on-site gas pressure is 0.8Mpa.
Cooling Air Flow Rate: Adjust the cooling air intake until a whistle sound is heard, indicating the minimum required flow rate.
Lateral Installation: Position the air intake on the flange facing downward.
Pre-Installation Check: Ensure the cooling air system is operational before installation and maintain continuous air supply during installation.
Stopping Cooling Air: Remove the Tube-11 from the application and allow it to cool before stopping the air supply. Seal the vent to prevent dust and water ingress.
Vent Safety: Keep non-heat resistant objects away from the vent, which discharges high-temperature gas. Label the vent with high-temperature warnings.
Distance Requirements: Maintain sufficient space between the meter housing and container wall, especially when installing laterally, with a recommended distance of over 40 cm.

Conclusion
Proper installation and adherence to guidelines are crucial for the reliable operation of the Tube-11 Ultra-High Temperature Vibrating Rod Level Switch in high-temperature environments.

Installation Guidelines of Ultra-High Temperature Vibrating Rod Level Switch-1

Installation Guidelines of Ultra-High Temperature Vibrating Rod Level Switch Targets at the ultra-high temperature working conditions with process temperature exceeding 250 ℃, Jiwei successfully developed Tube-11 Ultra-High Temperature Vibrating Rod Level Switch on the basis of its high-temperature model. It 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℃, which significantly expands its application field. The difference is an innovative cooling sleeve pipe is equipped. One end of the cooling sleeve pipe is welded to the process connection (flange) with air/water intake and vent, another end is connected with the vibrating probe. The air or water flow enters the inside of the vibrating probe through the capillary copper tube to take heat away, to cool the piezoelectric ceramic and wires to the allowable working temperature. This design makes the Tube-11 Ultra-high Temperature Vibrating Rod Level Switch can operate reliably at a temperature up to 400℃, and significantly expands its application field. To guarantee the reliability, there are detailed requirements and guidelines for the installation. Shenzhen Jiwei Automations Ltd.

Installation Guidelines of Ultra-High Temperature Vibrating Rod Level Switch-2

1. Air/water intake tube: select standard 6*4 (Outer Diameter 6mm) PU air tube. Cut a flat surface at the end of the tube, then insert to the air intake connector till the end, and screw the locking nut. It is recommended that the pressure of the on-site gas should be 0.8Mpa. 2. Minimum cooling air flow rate. The exhaust nozzle is fastened with whistle, and the outer wall of the exhaust nozzle is placed close to the inner wall on the side of the whistle vent. The cooling air intake rate is increased slowly until the whistle sounds. At this time, the corresponding cooling air flow rate is the...
