Ceiling temperature sensor RDF-IR active

infraredflush-mount4-20 mA

Ceiling flush-mounted sensor for surface temperature measurement in rooms, office spaces and other workplaces. Using the infrared measuring principle, an averaged temperature over the circular detection range (optical detection range 80 ±5°) is calculated. If two IR sensors are used, the mean, minimum or maximum value of both temperature signals can be provided in addition to the individually measured temperatures of each sensor (configurable via Thermokon USEapp). • Application/type : Ceiling sensor, Room sensor • Purpose : Measure values • Measured values : radiation temperature • Interface : Active, 0..5 V, 0..10 V, 4..20 mA, Switch contact • Configuration : USEapp, uConfig, jumper, DIP switches • Sensor : PIR (passive infrared), optical aperture angle (50% sensitivity): 80 ±5° • Output voltage : 0..10 V or 0..5 V, 2x 0..10 V or 0..5 V, adjustable via jumper, live-zero configuration via app or uConfig, min. load 10 kΩ • Output current : 4..20 mA, 2x 4..20 mA, max. load 500 Ω • Output switch contact : 2x floating contact NO for 24 V ~ or 24 V = / 3 A • Operating range temperature (°C) : -20..+70 • Output signal temperature : 0..+50 °C (default setting), selectable from 4 temperature ranges -40..+60 | 0..+50 | -20..+80 | -15..+35 °C, adjustable at the transducer • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,5 K (typ. at 21 °C), ±1,5 K (mounting height >7 m) • Power supply : 15..35 V = SELV, 19..29 V ~ SELV • Power consumption : typ. 0,6 W (24 V =), 1,5 VA (24 V ~) • Material in touch with media : temperature averaging over the circular detection area
