O2-Sensor for the measurement of oxygen concentration in furnace atmospheres
Oxygen Sensor:
New, revolutionary measuring procedure with a modified zircon measuring cell (heated) online attached at reactor. The measuring cell is equipped with an oxygen pump and permanently provides an exchange of the atmosphere at the measuring cell.
The oxygen pump works according to a physical principle similar to heat convection.
Features:
■ No wear, insensitive to contamination
■ Vacuum solid
■ No exhaust gas over the sensor
■ Pressure-insensitive measurement principle
■ Max. allowable measured pressure at sensor 7 bar
■ Vacuum proof up to 10-7 mbar
■ Reaction, depending on installation situation < 20s
■ Calculation of oxygen partial pressure according to Nernst at 750°C measuring cell temperature
■ Sensor dimension: 251 x 106 x 66 mm (L x W x H)
■ Measuring range: 0...100Vol% O2
Connections
■ Output signal: -1.500 mV up to +35 mV
-1500 mV correspond to 0 Vol% O2
0 mV correspond to 20,64 Vol% O2 (air)
+35 mV correspond to 100 Vol% O2
■ Supply: 24V DC / 1,5A
■ Mechanical connection: KF40 vacuum-flange
■ Measuring gas withdrawal over free entrance to furnace atmosphere or convection pipe
Accessories
■ Module rail power supply unit 24V/3A
■ 2m connecting line
