MAMAC Systems HU-226-3-VDC-12 Transducer
The MAMAC Systems HU-226-3-VDC-12 is a professional-grade duct humidity and temperature transducer engineered for high-demand HVAC and building automation systems (BAS). This unit features a high-performance bulk polymer capacitive sensing element protected by a proprietary ePTFE hydrophobic filter, ensuring reliable performance in environments prone to condensation, salt air, and pollutants. For precise climate control, it delivers 3% RH accuracy across a 0-100% range, combined with a 10,000 Ohm NTC Type II thermistor for accurate duct temperature measurement. Designed for maximum field flexibility, the HU-226-3-VDC-12 offers field-selectable 0-5VDC or 0-10VDC output via a simple switch, eliminating the need for multiple SKUs on the truck. The rugged NEMA 4 (IP65) steel enclosure and aluminum probe housing provide superior protection against mechanical stress and moisture. This analog humidity transmitter is compatible with 12-40VDC or 12-35VAC supply voltages and features reverse polarity protection and a half-wave rectifier power supply to safeguard integrated circuits during installation.
Key Benefits for Technicians:- Field Selectable Voltage: Toggle between 0-5VDC and 0-10VDC analog outputs to match specific controller requirements without extra hardware.
- Harsh Environment Protection: The ePTFE filter and NEMA 4 rated enclosure prevent sensor drift caused by contaminants and high-moisture conditions.
- Simplified Wiring: Includes an unpluggable screw terminal block for faster terminations and maintenance in tight ductwork spaces.
- Wide Supply Range: Compatible with common 24VAC/VDC power supplies, with support for 12-40VDC and 12-35VAC inputs.
- Integrated Temperature Sensing: Features a 10K Ohm Type II thermistor with ± 0.2°C interchangeability for streamlined dual-parameter monitoring.
Is the HU-226-3-VDC-12 compatible with generic 24V transformers?
Yes, but ensure the transformer is properly phased when powering multiple units. Use a dedicated isolation transformer if the controller lacks built-in isolation to prevent damage to the half-wave rectifier circuit.
Can the humidity sensor be cleaned?
The ePTFE filter protects the element from most debris. If the filter becomes clogged, it can be replaced; avoid using abrasive materials or chemicals directly on the capacitive sensing element to maintain 3% calibration accuracy.
How do I configure the output range?
The output is field selectable. Simply adjust the internal switch to your desired 0-5V or 0-10V range before applying power to ensure the BAS controller correctly scales the 0-100% RH signal.
