Specifications

Industry-leading weight & cable-based (plumb bob) smart level sensor for powder and bulk solids storage applications.

The heart of the SiloPatrol® SE Inventory Management System is an industry-leading weight and cable-based (plumb bob) “Smart” level sensor called the Silo Monitoring Unit (SMU SE) that is designed to perform in some of the harshest and most dynamic level measurement conditions. The SMU SE with its state-of-the-art sensors including Hall-effect technology can be combined with a variety of operator interface and auxiliary output options to provide a practical vendor / remote managed inventory system designed for your specific requirements.

 

Other features include:

> Level sensor is unaffected by material composition.

> On-demand measurement that can be triggered in addition to any automatic measurements.

> Innovative Hall-effect sensor array helps to eliminate the plumb bob from getting stuck in material by providing data to the microprocessor which in turn controls the amount of power to the robust direct-drive gear motor so it can pull the plumb bob harder if needed.

> Electronic lock-out to inhibit sensor from initiating a measurement cycle during filling operations.

> Split-compartment enclosure isolates all electrical and electronic components from the process environment to ensure long-term reliable operation.

> Uniquely designed wiper seal compartment for fast, easy servicing or replacement if necessary.

> Virtually maintenance free means that just a simple periodic “visual inspection” is recommended.

> Measuring range up to 150 feet (46m) for powder bulk solids material levels in bins and silos.

 

When a measurement cycle is initiated, either manually or automatically, the SiloPatrol® SE sensor (SMU SE) motor control system deploys a plumb bob, that is attached to a heavy-duty stainless steel cable, for descent into the vessel. The motor control circuitry regulates an optimal speed of descent that helps to eliminate cable slack, maximizes motor life and ensures that the plumb bob will stop when it contacts the material surface. The SMU SE measures the amount of cable deployed during descent via its unique optical sensing system. Once the optical encoder determines that the plumb bob has reached the material surface, the microcontroller reverses the direction of the motor and transmits the distance value. During the ascent of the plumb bob, the SMU SSEE measures the amount of cable retrieved in order to reconfirm the distance measurement.

 

Optional interfaces include the SiloTrack Inventory Management software and the HMI2 local operator interface control console. Wireless and AOE (auxiliary output) options are also available.
