Product Description – KFD2-WAV-EX1 Load Cell Transmitter
The KFD2-WAV-EX1 Load Cell Transmitter is a high-precision signal conditioning and intrinsically safe interface module designed for accurate weight and force measurement in hazardous industrial environments. Engineered for use with strain-gauge load cells, bridge sensors, and weighing systems, this transmitter converts low-level millivolt signals into a stable and interference-free analog output suitable for PLC, DCS, and SCADA control systems.
Built for process industries such as chemical plants, cement factories, oil & gas facilities, food processing, and bulk material handling, the KFD2-WAV-EX1 provides reliable measurement even in explosive atmospheres (Ex-rated zones). The device ensures safe isolation between the hazardous field side and the control room side, protecting both instrumentation and operators. Its intrinsically safe barrier design allows installation in control cabinets located in safe areas while directly interfacing with load cells installed in Zone 0/1/2 hazardous areas.
The transmitter offers exceptional measurement stability, temperature compensation, and excellent long-term accuracy. Advanced signal filtering minimizes electrical noise caused by motors, inverters, and heavy machinery, ensuring consistent readings in demanding industrial conditions. The module supports multiple load cell configurations and is suitable for hopper weighing, tank weighing, batching systems, belt scales, and silo monitoring.
Compact DIN-rail mounting simplifies panel installation and maintenance, while front-accessible terminals allow easy wiring and calibration. The device also provides diagnostic LED indicators for power and signal status, enabling quick troubleshooting. With galvanic isolation and intrinsic safety certification, the KFD2-WAV-EX1 enhances plant safety while improving measurement reliability and process efficiency.
The KFD2-WAV-EX1 Load Cell Transmitter is therefore an ideal solution for industries requiring precise weighing, hazardous area protection, and dependable continuous operation in harsh environments.
