Description
The HygroFlex3 (HF3S) series consists of highly efficient HVAC transmitters engineered for precise relative humidity and temperature monitoring in a sleek wall mounted enclosure. 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 HF332-S series stands out by delivering a sleek wall mounted transmitter with 3-Wire dual scalable 4-20mA analogue outputs. Ideal for architecturally sensitive installations, or where
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 and adjusted in the field using the AC3006 or AC3009 USB service interface paired with HW4 software.
- Space Enclosure Types: Discrete Wall (Type S) configurations with IP20-rated ABS housings.
- Three Standard Temperature Ranges: 0 to 50°C, -40 to 60°C and 0 to 100F.
- Loop-powered Configuration: Selectable as a 3-wire loop-powered (HF332) capable of supplying two separate current (4-20 mA) outputs.
- Low Ownership Costs: Outstanding value-engineered design with a long-term stability rating of < 1.5 %RH per year, dramatically reducing field maintenance intervals.
