Relative humidity and temperature sensor FTK+ RS485 Modbus

absoluteflange-mountdew-point

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, Active, 0..5 V, 0..10 V • Configuration : USEapp, uConfig, BUS, jumper, DIP switches • Output voltage : 2x 0..10 V or 0..5 V, adjustable via jumper, live-zero configuration via app or uConfig, min. load 10 kΩ • 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) • Output signal temperature : scaling analogue output, -20..+80 °C (default setting), selectable from 4 temperature ranges -40..+60 | 0..+50 | -20..+80 | -15..+35 °C, optionally configurable • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,3 K (typ. at 21 °C), within default measuring range, offset setting via app or uConfig • 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
