LI-24ALW Smart Temperature Transmitter
Brand: Aplisens S.A.The temperature transmitter LI-24ALW is applicable to converting resistance of temperature or voltage of thermocouple sensor to standard current signal 4-20 mA.
The transmitter has two separate channels enabling measurement of temperature difference, averange, averange with redundancy, max. or min. temperature.
Transmitter has compensation of ambient temperature influence and compensation of thermocouple cold junction using internal/external (Pt100) sensor or constant temperature.
Most of parameters such as: sensor type, measuring range, current alarm signal when electric circuit is broken, output characteristic correction, user characteristic (60 points) are programmed using PC with HART/USB converter and Aplisens RAPORT 2 configuration software.
For request Aplisens can set temperature transmitter parameters like measuring range, type of sensor. Their values are printed on label.
Transmitter LI-24/ALW is designed for field use. LI-24ALW can be used with temperature sensors mounted directly in transmitter’s casing or with external sensors connected with cable.
