DIN rail transmitter LKM 214 for Pt100 / Pt1000 resistance thermometers with output signal 0...10V
The LKM 214 is an analog transmitter for Pt100 / Pt1000 temperature sensors according to DIN EN 60751. It can be mounted on the 35mm top-hat rail. The temperature-dependent resistance signal of the sensors is converted into an output voltage signal of 0...10V. The output signal is highly accurate temperature linear. The transmitter is delivered from the factory calibrated to customer specifications. A span and zero controller allows subsequent fine adjustment. The influence of lead resistances is eliminated by using a 4-wire circuit. A larger distance between sensor and transmitter is therefore possible without loss of accuracy. The transmitter can also be used in a 2- or 3-wire circuit.
