EW-8 Checkweigher

The Model EW-8 is Alpha Checkweigher’s economical
solution for users and applications that may be new or unfa-
miliar with the advantages of checkweighing on new or ex-
isting filling, feeding, inspection, or other packaging lines.
Based on the field-proven line of Alpha Checkweighers, the
EW-8 offers the same versatility and reliability as other
Alpha models.

The EW-8 consists of a sturdy, tubular frame with a 5” U-
channel main support plate that serves as a mounting loca-
tion for the three belt-driven conveyors and the digital
strain gage loadcell. A slope front control console houses
the electronics and the color touch screen Human/Machine
Interface (HMI). Reject options include Air Blast, Pusher, or
Bopper to remove unacceptable weight packages from pro-
duction.

The EW-8 is operated and controlled from a series of full
color, easy to read and use screens on the front mounted
Touch Screen panel. Dedicated screens are provided for all
major functions and operations for testing, setting up, cali-
brating, and operating the checkweigher.
