The Oxygen Probe Assembly can be used for measuring the oxygen partial pressure in flue gases of industrial gas and oil fired heating systems or in oxygen control systems. The Oxygen Probe Assembly consists of a small ZrO2 oxygen sensor and an electronic interface circuit. The sensing element comprises two ZrO2 discs with a small hermetically sealed chamber in between. It is mounted at the tip of a stainless steel rod and is heated by an internal filament. The interface circuit. comprises a voltage amplifier for the sense signal, a constant current source for the pump and a 1 kHz amplifier for temperature control. . The Oxygen Probe Assembly has to be operated with a measuring assembly which controls the sensor operation and the signal processing. All specified data apply to operation with stabilised sensor temperature. The sensor is mounted at the end of a stainless steel rod which has a length of 311 mm (KGZ20), 411 mm (KGZ21) or 161 mm (KGZ22). The electronic interface circuit is housed within an epoxy coated aluminium box which has a Pg 9 cable gland. For new applications we recommend our MF range.
