LI-24 ALW Smart temperature transmitter


Manufacturer: Aplisens

The Smart 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, average, average with redundancy, max. or min. temperature.
