MAMAC Systems HU-227-3-VDC-12 Transducer
The MAMAC Systems HU-227-3-VDC-12 is a professional-grade outside air humidity and temperature transducer engineered for precision in demanding environmental monitoring applications. This dual-purpose sensor utilizes a thin-film capacitive HS-2000 sensing element to deliver 3% RH accuracy across a full 0-100% range. For temperature compensation and sensing, it features a 10,000 Ohm NTC thermistor (Type II), ensuring seamless integration with most building automation systems and controllers. The unit is built with a NEMA-4 (IP65) steel enclosure and moisture-sealed, conformal-coated electronics, making it resilient against salt air, contaminants, and high-condensation environments. An ePTFE Teflon filter protects the sensing element from water and dust while maintaining fast response times. Designed for versatility, the device offers field-selectable 0-5VDC or 0-10VDC output and accepts a wide supply voltage of 12-40VDC or 12-35VAC, providing HVAC technicians with a reliable solution for outdoor air intake or exhaust monitoring.
Key Benefits for Contractors:
- Dual Monitoring: Consolidates humidity and temperature sensing into a single ruggedized unit to reduce installation labor.
- Environmental Hardening: Conformal-coated circuitry and a NEMA-4 enclosure prevent failure in 100% condensing humidity.
- Universal Compatibility: Field-selectable voltage outputs and a standard 10K Type II thermistor match most BAS hardware.
- Maintenance-Free Design: The ePTFE filter allows air flow while blocking larger contaminants that cause sensor drift.
- Broad Power Range: Flexible 12-40VDC/12-35VAC input handles various power supply configurations found in the field.
Common Questions:
Can this sensor be used in marine environments?
Yes, the HU-227-3-VDC-12 features a rugged steel enclosure and conformal-coated electronics specifically designed to withstand corrosive salt air and high moisture.
What output is default for the humidity signal?
The unit features dip switches that allow a technician to select between 0-5VDC or 0-10VDC depending on the controller requirements.
Does this require a solar shield for outdoor mounting?
While the NEMA-4 enclosure is weather-resistant, mounting it in a shaded area or using a sun shield is recommended to prevent solar gain from affecting the 10K NTC temperature readings.
