Both level transmitters provide an analogue and switching output (4 to 20 mA as well as an NC SPST switch output) to provide continuous level indication of liquids or powder bulk material depending on the model.
The sensor in Series GWL and GWB guided wave radar transmitters outputs level indication as a continuous measurement reading through its analogue output, or it can alter that information into freely adjustable switching output signals.
Advanced time domain reflectometry technology in these radar transmitters enables excellent accuracy and stability, as well as suppression of disturbance signals, allowing both GWL and GWB to measure precisely even when operating close to interfering structures.
Common features of Series GWL and GWB guided wave radar transmitters:
- Available with a rigid or flexible probe depending on the application as well as custom probe length
- Restriction-free installation makes both models ideal for small tanks, tall and narrow nozzles, and various types of processing and storage applications
- Factory setting configuration via HART communication protocol
