Rotronic HygroFlex Series Driver for Tridium Niagara

The Rotronic HygroFlex Driver for Tridium Niagara provides precision environmental monitoring capabilities by integrating Swiss-engineered Rotronic sensors with modern building automation platforms, ensuring accurate temperature and humidity control in critical applications.

A key advantage of the HygroFlex Driver is its ability to leverage Rotronic’s industry-leading sensor accuracy (±0.8% RH, ±0.1°C) within the Niagara framework. Rather than relying on analog signal conversion with potential accuracy loss, the driver communicates digitally with sensors to preserve measurement precision. This direct digital integration eliminates calibration drift associated with analog transmitters and provides access to advanced sensor diagnostics, enabling predictive maintenance and ensuring continuous measurement reliability in regulated environments.

The driver communicates using Rotronic’s proprietary digital protocol over either RS-485 networks or Ethernet TCP/IP connections. For RS-485 implementations, up to 64 devices can be connected on a single network segment operating at configurable baud rates. During initialization, the driver automatically discovers all connected HygroFlex transmitters including wall-mount HF5x series, duct-mount HF8x series, and probe-style HP2x series devices. Beyond basic temperature and humidity values, the driver accesses calculated parameters including dew point, wet bulb temperature, enthalpy, and absolute humidity, providing comprehensive psychrometric data for advanced HVAC control strategies.

The HygroFlex sensor family represents Rotronic’s commitment to measurement excellence in demanding applications. Each sensor employs the company’s proprietary HygroClip2 technology, featuring digital signal processing and sensor-specific calibration data stored directly in the probe. This architecture ensures that sensors maintain their specified accuracy throughout their operational life, with recommended calibration intervals of 1-2 years depending on environmental conditions. The sensors’ robust construction withstands harsh industrial environments while maintaining laboratory-grade precision.

Rotronic AG, founded in 1965 in Switzerland, has established itself as a global leader in humidity and temperature measurement technology. The company’s focus on precision instrumentation for critical applications has made their products the standard in pharmaceutical manufacturing, museum conservation, data center operations, and semiconductor production. Their HygroFlex series, introduced as a digital evolution of analog transmitters, combines Swiss engineering precision with modern communication capabilities, making them ideal for integration into contemporary building automation systems.

If you’re managing critical environments where temperature and humidity control directly impacts operations, product quality, or regulatory compliance, Baudrate’s Rotronic HygroFlex Driver for Tridium Niagara is the ideal monitoring solution. The driver enables comprehensive environmental monitoring scenarios: implementing FDA-compliant monitoring in pharmaceutical facilities, protecting sensitive IT equipment in data centers, or maintaining precise conditions in laboratory and cleanroom environments.
