Data sheet

Description

The control unit AST 3P/ WST 3 is a digital process measuring amplifier. It can be connected to all strain gauge load cells. An unique and patented A/D converter with a high resolution of over 8 million counts serves as the heart of the transmitter.

The control unit is thus predestined for use in weighing systems for process control with a high accuracy requirement:

 

  • Process automation
  • Precise silo and container weighing
  • For inventory or process control


The control unit is equipped with a integrated LCD display and an operating keys for easy programming and good clearness of display.

 

The configuration and adjustment of the weighing systems can be carried out easily via the operating keys or with the deltaCOM software. All set-up data can be stored in the host computer and downloaded in case of replacement of the transmitter.

The control unit AST 3P/ WST 3 provides an analog output signal.
