Bridging wireless sensors and analogue control systems
17 April 2026 
To help industries integrate sensor data directly into existing control, automation, and data acquisition systems, Hottinger Brüel & Kjær (HBK) has announced it has re-introduced the WSDA-101
The WSDA-101 is a wireless gateway and is ideal for applications where predictable, low‑latency analogue signals are required, such as structural health monitoring, equipment performance monitoring, PLC‑based system control, and environmental monitoring. By converting wireless sensor data into standard analogue voltage outputs, the WSDA‑101 enables engineers to use wireless measurements within established workflows that rely on PLCs, DAQs, and controllers.
The WSDA‑101 provides eight independently configurable analogue output channels, delivering 0–3 VDC signals that can be connected directly to equipment requiring standard analogue voltage inputs. This approach allows wireless sensor data to be used in timing‑critical applications – including control loops, torque monitoring, and real‑time process feedback – without the need for custom hardware or complex system integration.
Designed for flexibility, the WSDA‑101 can operate as a standalone device or in parallel with a host computer via USB, supporting both factory floor and PC‑based workflows. Configuration, monitoring, and data collection are managed using SensorConnect software, providing a straightforward setup process for engineers working in test, measurement, and automation environments.
In addition to analog output operation, the WSDA‑101 supports LXRS lossless wireless communication when the analogue output mode is disabled. This enables reliable, high‑fidelity wireless data transmission across long distances for demanding measurement environments, such as spaces of up to 2 km in line-of-sight conditions.
The base station supports multiple sampling modes, including synchronised and low‑duty‑cycle operation, and is engineered to deliver consistent performance in applications requiring deterministic behaviour
With its combination of wireless flexibility and direct analogue output, the WSDA‑101 is intended for engineers seeking a practical way to incorporate wireless sensor data into established industrial and laboratory systems without redesigning existing infrastructure.
