DFCX-TR1000: The zirconium oxygen sensor
2018-07-02 05:03:51, Angst+Pfister Sensors and Power AG Pewatron has developed an oxygen transducer that can be easily screwed into process chambers and production equipment. The easy installation and standardized output signal make it the preferred solution for process control of oxygen concentrations in the ppm or % range. The FCX-TR1000 oxygen transmitter for the 0 to 1000 ppm range, which allows reliable measurement of oxygen concentrations in the very low ppm range, is the newest member of this successful product family from Pewatron.
It is a fully integrated solution with a low noise amplifier circuit that converts the µA signal from the sensor to a standard 4-20 mA output signal. In addition, the transmitter has high-precision, built-in voltage and current control for the sensor heating element. The transmitter thus ensures a similar accuracy as the sensor element itself. Depending on the application, the signal resolution is determined by the sensor element or the amplifier circuit. In the lowest case it is minimal +/-1 ppm. The four-pole connection cable of the transmitter can be very easily connected to a central power source. Just as easily, the output signal of 4 to 20 mA can be transmitted to a central PLC unit or output via a display screen.
