Load cell VMSQ-D
Load cell VMSQ-D is one of the most popular models of load cells submitting by manufacturer VMS. It applies for railway and truck scales. The present model of load cells possesses advantages such as explosion safety, impact resistance and high accuracy.
Digital load cells VMSQ-D in their design have built-in analogue-digital transformer (ADT). Digital signal about weight is transmitted under RS-485 interface that permits to increase considerably distance between weighing platform and weighing indicator (up to 1000 m).
Digital load cells have some advantages as compared with analogue models:
1. Digital technology protects equipment against fraudulent operations.
2. Unreceptive to external noise, pickup.
3. Continuous auto diagnostics of load cells.
4. Simplicity of maintenance and repair.
5. Possibility of removal of equipment up to 1 km.
