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.\u003c\/p\u003e\n \u003cul\u003e\n  \u003cli\u003eHumidity measurement 0% to 100% RH with ±2% accuracy and 4-20 mA output\u003c\/li\u003e\n  \u003cli\u003eTemperature sensing via 1000 ohm RTD (385) with resistance output; temperature compensated -30 F to +130 F\u003c\/li\u003e\n  \u003cli\u003eDuct mounting for HVAC\/BAS with hydrophobic ePTFE filter and NEMA-4 (IP-65) steel enclosure\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch4\u003eProduct Highlights\u003c\/h4\u003e\n \u003cp\u003eDuct-mounted humidity\/temperature transmitter with 4-20 mA humidity output and 1k ohm RTD temperature output\u003c\/p\u003e\n \u003ch3\u003eProduct Information\u003c\/h3\u003e\n \u003ch4\u003eStandard Information\u003c\/h4\u003e\n \u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MAMAC SYSTEMS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HU-226-2-MA-3\u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n \u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: Mamac Systems\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN\u003c\/strong\u003e: HU-226-2-MA-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HU-226 Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Type\u003c\/strong\u003e: Duct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHumidity Range\u003c\/strong\u003e: 0% to 100% RH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: ±2%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: 4-20 mA (humidity); resistance output (temperature)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Sensor\u003c\/strong\u003e: 1000 ohm RTD (385), platinum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Voltage\u003c\/strong\u003e: 24 Vac\/Vdc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Temperature\u003c\/strong\u003e: -30 F to +130 F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA-4 (IP-65) steel enclosure\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter\u003c\/strong\u003e: Hydrophobic and oleophobic ePTFE filter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Principle\u003c\/strong\u003e: Capacitive humidity sensor (cross-linked bulk polymer)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApprovals\u003c\/strong\u003e: CE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 lb\u003c\/li\u003e\n \u003c\/ul\u003e","brand":"MAMAC SYSTEMS","offers":[{"title":"Default Title","offer_id":51524825940274,"sku":"HU-226-2-MA-3","price":143.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82fb183f4e13e0cd81ce121252020b48.jpg?v=1785458743","url":"https:\/\/voomisupply.com\/products\/mamac-systems-hu-226-2-ma-3-duct-humidity-and-temperature-transmitter-24-vac-vdc-duct-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
