Checkweigher Weighing Controller


New ESİT ECI-CW, with its updated hardware, bright screen and superior product checking software, makes sensitive weight control in both dynamic and static conditions, easy and convenient. As ECI-CW includes all the features of standard ECI, can make dynamic weighing and produce rejection signals with its 800 Hz sampling rate. Product information can be entered to its memory and products can be chosen via controller’s menu.

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. Features
