Weighing Indicator with Analogue Data & Relay Outputs (ADW15)

This weighing indicator with analogue data & relay outputs, has a very flexible digital display system, optimised for single or multiple load cell and weighing applications and systems.

The ADW15 weighing indicator also has digital architecture that offers very easy one-pass calibration and fast setup.

Offering options of isolated analogue outputs, latching relays or digital outputs for control or alarm functions.

The RS232 or RS485 options on the ADW15 weighing indicator provide for digital communications (including setup) and can support label or ticket printers.

For a wall or surface mount version of the ADW15, see model SMW Weighing Indicator & Controller, and for a wireless radio version, see our range of T24 wireless sensor receivers & displays

Can be used in conjunction with our LCI load cell failure alarm, which is designed to continuously monitor the condition of individual load cells and activates an alarm when faults in the system are detected, therefore providing increased safety and cost savings onsite for all weighing systems.
