Electrotherm Digital Programmable Measuring Transducer 35V, -40°C to 85°C Operating Temperature LKM 262

Electrotherm LKM 262 digital programmable measuring transducer is precisely engineered for conversion of temperature dependent thermoelectric voltage from various thermocouples into a linear output signal ranging 0 to 10V. Designed for mounting on a 35 mm DIN-rail, it supports thermocouples types K, J, L, T, U, E, N, S, B, R, and C per DIN EN 60584-3, covering temperature ranges from -200°C up to 600°C depending on sensor calibration.

The transducer allows programmatic adjustment of zero point, enabling flexible temperature calibration between -200 to 600°C to fit various industrial process needs.

With a linearity error limited to 0.3 K and an overall measurement error of just 0.2%, this device ensures highly accurate temperature readings suitable for precision automation and control systems. Reference junction error is controlled tightly at +/- 0.5°C enhancing stability.

Operating reliably with supply voltages from 15 to 35 VDC or 15 to 26 VAC with reverse polarity protection and maximum current consumption of 20mA, the LKM 262 presents a robust power profile for industrial installations.

Its polycarbonate housing with dimensions 75x25x53 mm provides sturdy protection and minimal footprint within control panels. The device weighs approximately 60 grams, allowing for easy integration without significant load impact. Screw terminals with clamping capacity from 0.2 to 2.5 mm² support durable electrical connections.

Additional functional features include a rapid response time of 0.5 seconds, sensor break voltage set at 10V for malfunction signaling, and short-circuit condition resulting in voltage indicative of room temperature. The device tolerates humidity up to 95% and withstands vibration of 5g from 10 to 200 Hz making it suitable for harsh industrial environments.

The LKM 262 is compliant with EMC emission and noise immunity standards EN 61326-1:2006 and EN 61326-2-3:2006, ensuring interference-free operation in electro-magnetic noisy environments.

This transducer is ideal for use in industrial automation, laboratory instrumentation, HVAC controls, manufacturing process monitoring, and other precision temperature measurement applications. The universal interface LKM S1 allows straightforward programming and fine adjustment, enhancing usability.
