Air duct humidity and temperature sensor FTK+ Basic RS485 Modbus

relativeabsoluteflange-mount

Duct sensor for measuring relative and absolute humidity, enthalpy, dew point and temperature in gaseous media of heating, ventilation and air-conditioning systems as well as clean rooms. The optional features, such as relay outputs for 2-point controllers or 2-stage 2-point controllers and color-changing LCD allow for a wide range of applications. The accuracy of the humidity sensor is 2%. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. • Application/type : Duct sensor • Purpose : Measure values • Measured values : temperature, relative humidity, absolute humidity, enthalpy, dew point • Interface : RS485 Modbus • Configuration : BUS, DIP switches • Network technology : RS485 Modbus • Data transmission : RTU, half-duplex, baud rate 9.600, 19.200, 38.400 or 57.600, parity: none (2 stop bits), even or odd (1 stop bit) • Operating range temperature (°C) : -20..+70 • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,3 K (typ. at 21 °C), within default measuring range • Measuring range humidity : 0..100% rH non-condensing, 0..85 KJ/kg enthalpy, 0..50 | 0..80 g/m³ absolute humidity, 0..+50 | -20..+80 °C dew point, optionally configurable • Accuracy humidity : ±2% between 10..90% rH (typ. at 21 °C) • Power supply : 15..24 V = (±10%) SELV, 24 V ~ (±10%) SELV • Power consumption : max. 0,7 W (24 V =), 1,8 VA (24 V ~) • Material in touch with media : Pipe, PA6, with filter stainless steel wire mesh, black, Ø=19,5 mm • Installation length (mm) : 140, 270, 400 • Enclosure : USE-S, impact- and shock-resistant enclosure with quick-release cover, PC
