The Bindicator® Yo-Yo® is an electromechanical sensor which is mounted on top of a vessel.
The sensor contains a weight [A] suspended by a cable [B] with movement provided by a motor drive [C] and controlled by associated electronics.
The measurement cycle is initiated either on demand or on a timed interval and causes the sensor to lower the weight to the material level. As the weight is being lowered, the length of cable dispensed is measured in 1cm (0.39 in) increments.
When the weight reaches the material level, the unit reverses and the weight is drawn into the stored position in the sensor. The distance measurement can then be transmitted via 4-20mA to a PLC, DCS, or other device and/or via RS-485 MODBUS network to the Remote Display.
