Explore Our Current Transmitter Series by Output & Application

We categorize our current transmitter series by signal output and measurement type. This helps procurement managers and engineers quickly find the right specifications. Selecting the appropriate signal format is critical for seamless integration. It ensures long-term reliability whether you are upgrading legacy equipment or designing a smart grid.

4-20mA / 0-10V Analog Output Models

Our standard analog output models are engineered for traditional PLC integration and industrial control loops. These devices deliver high accuracy, typically around 0.5% FS, with response times under 10ms. Designed for standard 35mm DIN rail installation, every isolated current transmitter in this series offers strong anti-interference capabilities. This makes them ideal for harsh factory environments requiring reliable signal transmission.

RS485 Modbus-RTU Digital Transmitters

Our digital communication models provide advanced connectivity for modern IoT applications and smart grid power monitoring. These transmitters feature integrated RS485 outputs with Modbus-RTU protocols. This allows for direct communication with centralized control networks. Their low power consumption and isolated loop designs ensure long-term stability across extensive industrial networks.

AC/DC Hall Effect Current Sensors

Our specialized Hall effect sensors measure DC, AC, and pulse currents with exceptional precision. They are ideal for managing complex power loads. Available with specific aperture sizes like 12mm, a through-hole current transmitter suits high-current applications. These include electric welding, motor monitoring, and heavy hydraulic systems.
