SY045 Weight Indicator- Battery-Loop Powered

This Weight Indicator is a high precision instrument that requires just a nominal 3V (loop voltage) to operate.  The unit can be directly connected to up to 4 x 350Ω load cells or in an existing current loop to display scaled  measurements.

Weight Indicator Key Features

  • Easy installation
  • No power supply required
  • Clear 6 digit display with large 18mm digits
  • High accuracy 24 bit measurements
  • Works with 4-20mA current loops or Wheatstone bridge transducers
  • Loop voltage only 3.5V


Ideal for use in isolated tank farms.

The weight indicator is supplied as three versions in one (jumper selectable)


The weight indicator/digital panel meter is linked to loadcells and draws voltage required for operation from the loadcell excitation ( 4 – 14Vdc).  These are ideal where an indication of a tank content is required and load cells are being excited by a separate control system either a Synectic SY005 batch weigher or SY017 recipe batch controller for example. (It is not essential that it is Synectic instruments)


The unit operates as a 4-20mA loop indicator placed in an existing current loop will drop just 3V from the loop.


The battery powered weight indicator gives load cell excitation for remote areas.

Standard battery to fit inside SY045 = 4.8V 2600mAh NiMH gives 10 x 24 hour  days with 700R bridge, 5 days with 350R bridge.

Larger longer life batteries can be connected if required but would need a separate external battery box.
