Oxygen sensors

We differentiate between two typical oxygen measuring systems:

• Inline Oxygen Measuring
• Extractive Oxygen Measuring

Sensors, which extend into the process, are called inline sensors.

Sensors, which require measuring gas to be taken from the process, are called extractive sensors.

In order to account for the manifold measuring requirements and conditions at the measuring locations, our many years of experience have led us to develop a number of versions of oxygen sensors and electronic measuring devices.

Oxygen sensor A15-N

Extractive oxygen sensors for stationary use can be easily adapted to the method. Zirconium oxide as measuring principle allows an universal use. Bodies of stainless steel and aluminium top join industry standard and insensitivity.

At sensor A15 the measuring gases are withdrawn from the test area and passed through the sensor.

These sensors have to be connected with a measuring module or a supply module.

Technical data A15-N

Incorporation position	No limitation
Gas entry	G 3/8 inch
Gas exit	G 1/4 inch
Measuring principle	Zirconium oxide
Gas flow	50 to 80 l/h. The flow is generated by overpressure of unit or by differential pressure of unit or by pump.
Condensate protection	For the attachment of the gas pipes an inclination of the pipes away from the sensor is important so that the condensate which optionally crops up cannot flow into the sensor.
Electrical connection	Within the connection top there is a multipole plug at which the connecting cable to the transformer module or the measuring module is connected.
Material connection top	Aluminium pressure casting housing
Material sensor part	Stainless steel V2A
Heating	About 700 degrees by connection to the supply module Z15 or the measuring module of series ‘Z’ or ‘U’.

Oxygen sensor A05

Oxygen sensor for ceramic furnaces

Performance characteristics:

This basic inline sensor has been specially designed for use in ceramic furnaces in order to document the oxygen content in the combustion gas.

The design is characterised by simple, functional components. The sensor is connected with an evaluation unit, which displays and/or controls the oxygen content or the lambda value of the combustion. In most cases our GSM type measuring and control instrument will serve this purpose best.

Technical data A05 sensor

Oxygen sensor A19-N

The sensor requires a series U or Z supply unit in order to function.
Please refer to the unit's operating instructions for additional information.

Oxygen sensor CMM / CSM

C-Sensor serie

Inline oxygen sensors directly measure in the high temperature process. Zirconium oxide as measuring principle allows an excellent interpretation for heat treatments, especially in the field of oxidation, reduction and carburizing. Highly alloyed stainless steel and special ceramics guarantee long-term stability and corrosion control.

The oxygen sensor of the CM type series has been developed especially for inline measurement at gas carburizing.

As external protecting tube for the standard version a steel 1.4841 is used. Special alloys if desired are available. Operational temperatures of 700 to 1.000 degrees are covered.

The CSM type series has been developed especially for inline measurement in oxidizing and reductive atmospheres.

As external protecting tube in the standard version a ceramic material of aluminium oxide with an internal electrode of platinum is used.

A special use at high temperature carburizing is intended.

Operational temperatures of 700 to 1.400 degrees are covered.

Oxygen sensor CLX (Basis)

Oxygen sensor of the CL series

The CM and CL type series has been developed especially for inline measurement at gas carburizing.

As external protecting tube for the standard version a steel 1.4841 is used. Special alloys if desired are available.

The CLX type series is a basic variant with a metal protecting tube.

Operational temperatures of 700 to 1.000 degrees are covered.
