It combines a capacitive humidity sensor with a 10K Type II thermistor into a single probe assembly measuring 6.80 inches in length. The unit operates on 24 VAC or 24 VDC and delivers a 4-20 mA output signal, making it straightforward to wire into building automation systems and DDC controllers. Humidity accuracy is rated at 2%. An onboard LCD provides local readout of measured values, and outputs are field selectable so technicians can configure the unit on-site without additional hardware. Licensed HVAC controls technicians and building automation specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThe HT1D-2EUD is suited for a wide range of commercial and institutional environments where duct air conditions must be monitored continuously. Typical applications include humidification and dehumidification control, supply air, discharge air, and return air sensing, economizer control, clean rooms, data centers, process control environments, schools, hospitals, and office buildings. The duct-mount form factor allows the probe to be inserted directly into the airstream without requiring an external enclosure or additional mounting accessories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2% humidity accuracy for reliable control signal quality\u003c\/li\u003e\n\u003cli\u003e6.80-inch probe length sized for standard duct insertion\u003c\/li\u003e\n\u003cli\u003e10K Type II thermistor provides simultaneous temperature measurement\u003c\/li\u003e\n\u003cli\u003e4-20 mA output compatible with most DDC and BAS input cards\u003c\/li\u003e\n\u003cli\u003eField selectable outputs allow on-site configuration without factory programming\u003c\/li\u003e\n\u003cli\u003eLCD display gives local visual readout of measured values\u003c\/li\u003e\n\u003cli\u003eOperates on 24 VAC or 24 VDC low-voltage power\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style duct humidity and temperature transmitter for use in commercial HVAC systems requiring 4-20 mA analog inputs and 24-volt low-voltage control power.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed HVAC controls technician or building automation specialist. De-energize the air handling unit and confirm 24-volt power is off before inserting the probe or making wiring connections. Follow NEC low-voltage wiring guidelines when routing signal and power conductors. Verify duct probe insertion depth and seal the duct penetration around the probe fitting to prevent air leakage after installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHumidity Accuracy\u003c\/strong\u003e: 2%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Length\u003c\/strong\u003e: 6.80 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Element\u003c\/strong\u003e: 10K Type II Thermistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Signal\u003c\/strong\u003e: 4-20 mA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Requirements\u003c\/strong\u003e: 24 VAC, 24 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay\u003c\/strong\u003e: LCD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Duct\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Poly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SENVA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HT1D-2EUD\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SENVA","offers":[{"title":"Default Title","offer_id":51283929694514,"sku":"HT1D-2EUD","price":261.68,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279061.jpg?v=1781063463","url":"https:\/\/voomisupply.com\/products\/senva-ht1d-2eud-duct-humidity-temperature-transmitter","provider":"Voomi Supply","version":"1.0","type":"link"}
