WDT11 - amplifier for force sensors

WDT11 is a universal amplifier for strain gauges of force. Thanks to the digital transducer, it allows you to precisely measure the volume and convert it to a 4-20mA (or 0-10V) and digital (RS485) signal.

The built-in RS485 interface with the MODBUS protocol allows direct communication of one or several modules with a PLC or HMI panel. It is possible to connect up to 32 modules on one bus.

The configuration of the module is carried out via a USB connector and dedicated software, which, in addition to the device settings, also makes it possible to view current measurement values.


  • WDT11-I (version with 4-20mA output)
  • WDT11-U (version with 0-10V output)


  • Measurement from a strain gauge (4 or 6 wire)
  • Converting values into selected units
  • Configurable sampling and filtering frequency
  • Analog output (0)4-20 mA (or 0-10 V)
  • RS485 interface with the MODBUS protocol
  • USB connector for device configuration
  • Built-in button and external tare connectors
  • Operation status indication by LED diodes
  • Power supply for 12-24 VDC devices
  • Mounted on a DIN rail or with handles
