Versatile Application Possibilities for the SITRANS LVS200

The SITRANS LVS200 is designed for a wide range of bulk solid and liquid/solid interface applications, ensuring reliable performance in various industries. It can be mounted in different positions to suit specific process needs, making it highly adaptable. With its robust and compact design, it detects levels accurately and prevents false readings, even in harsh conditions.

Key Applications:

• High, low, or demand level detection of dry bulk solids in bins, silos, and hoppers
• Detection of settled solids within liquids (liquid/solid interface version)
• Use in confined spaces, such as feed pipes
• Buildup monitoring with optional 4 to 20 mA output for preventative maintenance
• Reliable performance in sticky or challenging environments.

Installation Guidelines for SITRANS LVS100/200

Installation of the SITRANS LVS100/200 should only be carried out by qualified personnel, adhering to local regulations. When installing, avoid bending, shortening, or extending the tines. To position the tines, use a 50 mm open-end wrench on the process connection—do not rotate the housing itself.

For side mounting, ensure the tines are oriented vertically, with the marking on the tine facing up or down. In pressure applications, seal tapered threaded connections with PTFE tape or another appropriate sealant.

After installation, verify that cable entries face downward to prevent water ingress, and be mindful that the torque from material loading must not exceed 250 Nm. For the 1½" thread connection, ensure the mounting torque does not surpass 80 Nm.

Mounting Considerations for Effective Detection

Typically, SITRANS LVS100/200 is mounted at the top of the vessel for full detection or through the tank wall for full, demand, or empty level detection. It is crucial to position the tines vertically to prevent product buildup by rotating the process connection with a 50 mm open-end wrench until the orientation marking faces up or down.

Angle mounting should only be used for flowing material applications. If angle mounting is necessary in areas with heavy material loading, protective measures must be in place to safeguard against falling material.
