Datasheet

HygroFlex 3 Transmitter

  • Description
  • Additional information

Description

The HygroFlex3 (HF3R) series consists of highly efficient HVAC transmitters engineered for precise relative humidity and temperature monitoring in a Space mounted enclosure with retractable probe. 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-R series stands out by delivering a versatile wall mounted transmitter with dual scalable 0-10V analogue outputs. Ideal for a discrete temperature and humidity monitoring unit with a retractable probe, for area that can see contamination.

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.
  • Room Enclosure Types: Room (Type R) configurations with retractable probe, housed in a IP20-rated ABS enclosure.
  • Three Standard Temperature Ranges: 0 to 50°C, -40 to 60°C and 0 to 100F.
  • Output Configuration: Selectable as a 3-wire loop-powered (HF335) capable of supplying two Voltage (0-10V) 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.
