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 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 temprature sensors mounted directly in transmitter’s casing or with external sensors connected with cable. universal thermoresistance input Pt100 and thermocouple J, K, S, N, E 2-wire current output 4÷20mA with power supply in current loop power supply: 2-wire output: 12 ÷ 36 Vdc 3-wire output: 18 ÷ 30 Vdc relative humidity range: 0÷90 % (no condensation) industrial housing (IP65) made of polycarbonate, dimensions: 58x64x35 mm option of programming the input type, range of processing and other device parameters using AR956 or AR950 programmer
