LKM 261 Digital Programmable Measuring Transducer

The LKM 261 is a digital programmable measuring transducer intended for mounting on a standard rail. The transducer can be programmed for different thermocouples according to DIN EN 60584-3. The LKM 261 converts the temperature dependent thermoelectric voltage of the sensors into a standard signal which ranges from 4 to 20mA. The temperature compensation is effected within the measuring transducer. The transducer can be programmed by using the universal interface type LKM S1 which is available from RS. An adjusting controller allows immediate minor display corrections
