Condensation detector WK02+ RS485 Modbus

humidityLEDradio

Condensation sensor with an LED signal and a relay output to prevent condensation on chilled surfaces. For control and monitoring applications or connection to cooling valves to stop the flow of chilled water flow upon condensation. The 'ext.' model uses a 2m remote sensor for a more flexible installation. • Application/type : Condensation sensor • Purpose : Measure values • Measured values : temperature, relative humidity, absolute humidity, enthalpy, dew point, condensation • Interface : RS485 Modbus, Switch contact • Configuration : USEapp, BUS, DIP switches • Output switch contact : changeover contact, floating, max. 250 V ~, 1 A resisitve load • Network technology : RS485 Modbus • Radio technology : LoRaWAN® (868 MHz) • 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) : 0..+50 • Operating ranges temperature (°C) : 0..+50 • Output signal temperature : scaling analogue output, 0..+50 °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 : ±0,5 K (typ. at 21 °C) • 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), potentiometer to adjust the sensitivity • Power supply : 15..24 V = (±10%) SELV, 24 V ~ (±10%) SELV • Power consumption : typ. 0,8 W (24 V =), 1,6 VA (24 V ~)
