Temperature Transmitter P 44000

Precise Temperature Measurement at High Voltage Potentials up to 6 kV. ProLine P 44000 transmitter for high-voltage applications converts the resistance of a 2- or 4-wire Pt100 resistance thermometer into a 4 to 20 mA signal with high accuracy and short delay times.

The output signal is galvanically isolated from the input signal and the voltage supply. The isolation is designed for working voltages of up to 6 kV AC/DC. During routine testing, the test voltage is 15 kV AC. Vacuum encapsulation protects the circuit against environmental influences and ensures that the extraordinary isolation properties are maintained.

The product line covers the standard ranges of 0 to 150 °C, 0 to 200 °C and 0 to 300 °C. The transmitters are available in 67.5 and 22.5 mm modular housings to suit different requirements.
