Relative humidity and temperature sensor LK series

absolutedew-point4-20 mA

Humidity and temperature transmitter optimised for HVAC – LK, economical transmitters – L-series is primarily optimized for ambient room conditions. It is very suitable to monitor energy costs in HVAC and building automation applications. Moderate industrial conditions Thanks to its high quality manufacturing, the LW transmitter can also be used in moderate industrial conditions. Optionally, it can be equipped with a PTFE filter with an IP65 degree of protection. A extra sealing can protect against increased requirements (e.g. condensation). It also can be made resistant to vibrations. With analogue output The transmitters with analog output have a very stable current or voltage signal. Hx-values via Modbus The hx values ​​can be read using the RS485 Modbus RTU protocol. The measured values ​​of relative humidity and temperature are used to calculate enthalpy, absolute humidity, air/water mixing ratio or wet bulb temperature. Capacitive MELA® sensorchips Equipped with the highly dynamic capacitive MELA® sensor element, the sensor provides reliable performance across the full humidity range. Using the MELA® sensor element ensures long-term stability, resistance to dew formation, minimal hysteresis, and strong dynamic capabilities.
