MAMAC Systems HU-226-2-MA-12 Transducer

MAMAC Systems HU-226-2-MA-12 Transducer

The MAMAC Systems HU-226-2-MA-12 is a high-performance duct humidity and temperature transducer engineered for demanding HVAC automation and Building Automation Systems (BAS). This dual-purpose instrument features a bulk polymer capacitive sensing element, ensuring ± 2% RH accuracy across a full 0-100% range. Designed for technicians who prioritize long-term stability, the humidity sensor is resistant to condensation and contaminants, maintaining NIST traceable calibration even after exposure to harsh environments. For simultaneous thermal monitoring, it integrates a precision 10,000 Ohm NTC thermistor (Type II) with an interchangeability of ±0.2°C, providing a reliable resistance output for temperature.

Housed in a rugged 18-gauge steel NEMA 4 (IP65) enclosure, the unit is built for duct mount applications in schools, hospitals, and clean rooms. The 4-20mA 2-wire output for humidity allows for seamless integration into standard current loops, supported by a wide 12-40Vdc supply voltage. With non-interacting zero and span trimmers, field calibration is straightforward for any HVAC contractor maintaining system precision.

Key Benefits:
  • High Precision Monitoring: Delivers ± 2% relative humidity accuracy and 10K Type II thermistor temperature sensing in one duct probe.
  • Industrial Durability: The NEMA 4 enclosure protects sensitive electronics from dust, moisture, and corrosive airborne contaminants.
  • Field Reliability: Features short circuit and reverse polarity protection, alongside an ePTFE filter to shield the polymer capacitance sensor.
  • Universal Compatibility: Standard 4-20mA output and 10K Ohm thermistor curve ensure simple pairing with most DDC controllers.
Common Questions:

How do I wire the HU-226-2-MA-12 for humidity?
This is a 2-wire 4-20mA device. Connect the positive supply (12-40VDC) to the [+] terminal and the controller’s analog input to the [-] terminal to complete the current loop.

Can the sensor handle high-moisture environments?
Yes, the bulk polymer sensor is designed to withstand 100% humidity and condensation. If the probe becomes fouled by contaminants, it can typically be cleaned with isopropyl alcohol without shifting the calibration.

What is the temperature range for this duct transducer?
The unit is temperature compensated for operation between -30°F and 130°F (-35°C to 55°C), ensuring accuracy across seasonal temperature swings in air handling units.
