Description
The HygroFlex1 (HF1) series consists of highly efficient HVAC transmitters engineered for precise relative humidity and temperature monitoring. Equipped with the Hygromer® IN-1 capacitive sensor, these instruments convert environmental conditions into linear analogue output signals for seamless integration with automation networks. They function as fundamental building blocks for modern climate control tracking, optimising indoor comfort and commercial energy efficiency.
While standard HVAC instruments compromise performance for affordability, the HF1 series stands out by delivering long-term calibration stability and dual freely scalable analogue outputs. Its versatility is further amplified by diverse installation enclosures—including robust wall and duct form factors, alongside a dedicated space-mounted profile for architecturally sensitive installations.
Features
- Proven Sensing Technology: Integrated with the Hygromer® IN-1 capacitive humidity sensor and high-stability thermistors for dependable, repeatable measurements.
- Flexible Scalability: Features two analogue outputs that can be freely scaled, configured, and adjusted in the field using a standard mini-USB service interface paired with HygroSoft software.
- Diverse Enclosure Types: Available in robust Wall (Type W) and Duct (Type D: 100 mm / Type F: 300 mm) configurations with IP65-rated ABS housings, plus a sleek Space Mount (Type S) variant with an IP30 enclosure.
- Configurable Circuit Topologies: Selectable as a 2-wire loop-powered (HF120) or a versatile 3/4-wire (HF13x) configuration capable of supplying either current or voltage signals.
- Low Ownership Costs: Outstanding value-engineered design with a long-term stability rating of < 1.5 %RH per year, dramatically reducing field maintenance intervals.
