Yo-Yo^®

The GP-4- and Mark-4 Yo-Yo® sensors are designed to provide accurate and reliable inventory management information for tanks and silos. 

The Yo-Yo® system is simply and quickly installed on top of the silo. The Yo-Yo® is dropped either manually or on a timed interval into the silo. As soon as it makes a contact it returns to the park position measuring the covered distance which is relevant to the amount of available material. The advantage is here the highly robust yet extremely sensitive mechanical rollers that prevent jamming or tearing of the cable.

The GP-4 is housed in a NEMA 4 enclosure. The Mark-4 Yo-Yo® sensor is housed in a NEMA 4/7/9 enclosure.  The BINDICATOR® remote display/programmer can request readings, monitor up to 99 GP-4 and Mark-4 sensors, and program silo parameters. The display/programmer allows a user to configure a single sensor or a whole system.  An adjustable autotimer allows the user to set automatic measurement cycles ranging from 2 minutes to 1 week. While in operating mode, the display will show the sensor address, sensor name, measurement in the specified units, percentage, display mode and the status of the current device.

Typical applications for the use of the Yo-Yo® system are aggregates, granules, plastic resin, pellets, powders, liquid/solid interfaces.
