What it does

Accepts and displays load cell/strain gauge input. Offers relay output for alarming plus optional serial communications and analog output. Supplies excitation.
This popular weighing/load cell meter and controller is designed to accept standard 4-6 wire bridge type load cell inputs directly, and features a built in 2x 8-digit LCD display for simple operator interface. It includes advanced batching features and is ideal for filling and emptying applications.

At a glance:

  • 4-wire or 6-wire strain gauge, 1-5mV/V
  • Signal conditioning
  • Dual relay outputs
  • Optional advanced batching functions for filling/emptying applications
  • Customisable display, front panel button and rear input pins
  • Gross/batch weight
  • Zero offset
  • Automatic zero maintenance
  • Input signal averaging
