Electrotherm Digital Programmable Measuring Transducer 35V, -40°C to 85°C LKM 261

Electrotherm LKM 261 is a digital programmable measuring transducer designed for precise temperature measurement and control in industrial environments. It converts the temperature-dependent thermoelectric voltage from various types of thermocouples into a standardized 4 to 20 mA current loop signal. The device supports thermocouples type K, J, L, T, U, E, N, S, B, R, and C within specified temperature ranges according to DIN EN 60584-3 standards.

The transducer operates reliably within a temperature range of -40°C to 85°C and a supply voltage up to 35 V DC, featuring reverse polarity protection to enhance durability in harsh conditions. Its compact polycarbonate housing (75 x 25 x 53 mm) mounts conveniently on a 35 mm DIN-rail, saving space in control panel installations.

Equipped with screw terminals accommodating wire sizes from 0.2 to 2.5 mm², the LKM 261 ensures secure electrical connections. The device's fast response time of 0.5 seconds and high measurement accuracy - with a linearity error of 0.3 K and a reference junction error of ±0.5°C - make it ideal for critical temperature monitoring tasks.

This transducer is resistant to moisture levels up to 95%, and withstands vibrations up to 5 g in the frequency range 10 to 200 Hz, ensuring stable operation in industrial and process control environments. The output current signal maintains the loop voltage between 10 and 35 V DC and includes sensor break and short circuit protections to prevent malfunctions.

Compliance with EMC emission and noise immunity standards EN 61326-1:2006 and EN 61326-2-3:2006 guarantees reliable operation in electrically noisy industrial settings. Originating from Germany, this new-condition product is perfect for automation and control gear applications demanding precise and programmable temperature measurements.
