WT2 Weight Transmitter
WT2 Weight Transmitter
Sku: VIS-WT2
The WT2 Weight Transmitter combines accurate weight measurement with enhanced industrial connectivity. Designed for systems using 1–4 load cells, it features a 24-bit converter and PROFIBUS communication as standard. Optional Ethernet connectivity with a 128-byte input/output buffer and PROFINET support enables high-speed communication and integration with complex industrial control systems.
Product Information
The WT2 is a modified version of the WT1 with improved interfacing abilities. It uses the same 24-bit D/A converter and, when connected to a system of 1–4 load cells, the WT2 converts output signals in the same manner as the WT1. The WT2’s strength is in its connectivity. It uses PROFIBUS as its default protocol, which is faster than
the MODBUS protocol and able to control more complex systems. The WT2 also features an optional Ethernet connection with a 128-byte in/out buffer for high-speed PC connections. The Ethernet cable can be augmented with the PROFINET protocol, enabling full integration with systems that support it.
