• LKM 282 Digital Programmable Measurement Transducer
• The LKM 282 series is a digital programmable galvanic insulation measurement transducer for thermocouples.　This transducer is mounted on a standard rail.　The LKM 282 transducer is designed for automotive use.　This transducer is high interference resistant and can handle a wide range of voltages (even 8 V supply voltage which can obtain a 10 V linear output signal).　Because of its thin 6 mm design, this transducer takes up only a small amount of space on the standard rail and provides optimal impact resistance.　Another advantage for all users is that the measuring transducer can program various thermocouples to comply with DIN EN60584-3. The sensor thermal voltage EMF is converted to an output signal in the range of 0 to 10 mA linearly with temperature.　This temperature compensation is applied within a measurement transducer configured via a micro USB port.
