Smart Temperature Transmitter TTS-LI-24ALW
The temperature transmitter LI-24ALW is applicable to converting resistance of temperature or voltage of thermocouple sensor to standard current signal 4-20mA. The transmitter has two separate channels enabling measurement of temperature difference, averange, averange with redundancy, max. or min. temperature. Transmitter has compensation of ambient temparature 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 RAPORT 2 configuration software. Upon request the temperature transmitter parameters like measuring range, type of sensor can be set. Their values are printed on label. Transmitter LI-24/ALW is designed for field use. LI-24ALW can be used with temprature sensors mounted directly in transmitter’s casing or with external sensors connected with cable.
