Electrotherm Digital Transducer

The LKM 262 is a digital programmable measuring transducer which is for mounting on a standard rail. The transducer can be programmed for different thermocouples according to DIN EN 60584-3. The LKM 262 converts the temperature dependent thermoelectric voltage of the sensors temperature linearly into a standard signal. The signal ranging from 0 to 10V. The temperature compensation
is effected within the measuring transducer itself. The measuring transducer can be programmed by using the universal interface, LKM S1 which is available from RS. An adjusting controller allows immediate minor display corrections.
