Silo (Tumba) Scale Weighing Controller


With its updated hardware, bright screen and hopper scale software structure; New ESİT ECI indicator presents functionality, performance and ease of use significantly higher than industrial standards. Bearing standard ECI Indicator’s all features, ECI-HS offers adjustable coarse-fine filling, amount filling, flow measurement features and automatic shoot calculating, which eases automation.


With the standard feature of “Calibration Doctor”, ESIT ECI indicator allows users to calibrate systems with simple steps, while calibration quality is inspected. Therefore wrong or incomplete calibration is prevented. Furthermore calibration can either be made with standardized weights, digitally via input values or via load cell mV input. Since a backup can be taken of calibration values to the main board of the indicator; calibration values cane be restored in case of a fault.

gResolver Special Filtering

ESIT ECI Weighing Indicator includes gResolver filtering software, an ESIT design. gResolver Special Filtering software filters all damaging vibration effects on weighing operations, enabling both sensitive and fast weighing.
