Electrotherm Digital Transducer | LKM 282

The LKM 282 series is a digital programmable galvanically isolated measuring transducer for thermocouples. The transducer is mounted on standard rails. The LKM 282 transducer was designed to be used in cars. The transducer has a high interference immunity plus a wide range of voltages even a supply voltage of 8V you can obtain a liner output signal of 10V. A slim 6mm design means this transducer takes little space on a standard rail and has optimum shock resistance.
An added benefit to all users is that this measuring transducer can be programmed for a variety of thermocouples all to DIN EN 60584-3.The sensors thermoelectric emfs are converted temperature linearly into the output signal which ranges from 0 to 10V. This is where temperature compensation takes place within the measuring transducer which is configured via a micro USB port.
