Mamac Systems HU-226-2-MA-3 Duct Humidity and Temperature Transmitter 24 Vac/Vdc (Duct Mount)

Product Description

Mamac Systems HU-226-2-MA-3 is a duct-mounted humidity and temperature transmitter that measures 0% to 100% relative humidity with ±2% accuracy and provides a 4-20 mA humidity output plus a resistance output for temperature. It uses a 1000 ohm RTD (385) temperature sensor, operates on 24 Vac/Vdc power, and is designed for HVAC and building automation duct applications. The sensing element is capacitive with a hydrophobic ePTFE filter and the unit is temperature compensated for -30 F to +130 F.

• Humidity measurement 0% to 100% RH with ±2% accuracy and 4-20 mA output
• Temperature sensing via 1000 ohm RTD (385) with resistance output; temperature compensated -30 F to +130 F
• Duct mounting for HVAC/BAS with hydrophobic ePTFE filter and NEMA-4 (IP-65) steel enclosure

Product Highlights

Duct-mounted humidity/temperature transmitter with 4-20 mA humidity output and 1k ohm RTD temperature output
