ADW-LW

The ADW15 is a very flexible digital indicator and display system in a panel mount format, optimised for single or multiple load cell and weighing applications. The digital architecture offers very easy one-pass calibration and fast setup. This versatile amplifier panel meter offers options of isolated analogue outputs, latching relays or digital outputs for control or alarm functions. The RS232 or RS485 options provide for digital communications (including setup) and can support label or ticket printers. For a wall or surface mount version, see model SMW Weighing Indicator / Controller, and for a wireless telemetry version, see model TDUDIS Radio Telemetry Display Module.

The ADW-LW Weighing Indicator / Controller for Loss in Weight version adds the capability to manage and control the fill by the loss-in-weight method of containers such as bags, drums, etc, and provides sufficient control capability to allow for stand-alone operation without the need for a PC or PLC.

Other specialised versions of the model ADW15 Weighing Indicator / Controller exist for the following functions :

• ADW-BW - Batch Weighing - up to 12 components or ingredients
• ADW-FFW - Fast Filling for bags, bottles, etc
• ADW-SP16 - Process weighing with up to 16 setpoints

Standard ADW15 features include:

• Provides excitation of 10V @ 160mA to drive up to 6 x 350 Ohm load cells
• Variable gain input sensitivity from 0.5 to 200 mV/V
• Six wire measurement system can compensate for zener barrier losses
• Fully digital set-up and calibration using built-in LED display and keypad or comms
• Simple one pass auto calibration for minimum set-up time on site
• Auto tare and peak hold actioned by volt-free contacts
• Setpoints and event handling using digital inputs and 2 x SPCO relays
• Programmable in-flight compensation for dynamic weighing operations
• High accuracy and high stability over a wide temperature range
• Fully isolated 4~20mA and 0-10V analog outputs
• RS232 or RS485 communications for setup, data transfer or label/ticket printing
• Small panel space - DIN 72 x 72 mm - DIN rail mounting kit available
• AC or DC power supply options

Additional features provided by the ADW-LW version are:

• Tests for sufficient hopper contents prior to initiating the fill
• Hopper replenishment and taring performed automatically
• System speed optimisation (self-learning)
• 'Weight complete' output and totaliser functionality
• Stand alone system or additional control with PLC
