Which cables can be found in the B+B online shop?

We offer connection cables, compensation cables, copper cables, thermocouple wires, thermocouple cables and extension cables.

What are the advantages of a glass fibre cable?

Glass fibre cables are highly temperature-resistant and can withstand very high temperatures (up to 400 °C). This is the biggest advantage of glass fibre cables over other cable insulation materials such as PVC, silicone or PFA.

Are other lines or larger quantities available?

On request, we can offer numerous other cables, including in larger quantities.

Which cables are suitable for the respective application?

Please feel free to contact us by telephone, we will be happy to advise you!

What is the difference between a thermal cable and a compensation cable?

Compensation cables consist of so-called substitute materials, which have a different chemical composition than the materials of the corresponding thermocouple. The substitute materials have the same thermoelectric properties as the corresponding thermocouple within the permissible application temperature range for compensation cables. A thermocouple cable consists of the same metals as the thermocouple itself. Compensation cables are often less expensive than thermocouple cables.

What kind of types of gas probes does B+B have?

At B+B, you will find various gas probes that differ from one another in terms of their operating principle and thus their area of application. B+B Thermo-Technik GmbH's product range basically includes flue gas probes, a multi-hole probe and exhaust gas probes.

What does the installation of this sensor look like?

When installing the duct sensor, the sensor tube should point downwards to prevent measurement errors due to the self-heating of the electronics. It should be noted at this point that the sensor has a certain degree of pressure resistance at the head, but is not suitable for use with compressed air at higher pressures. If the sensor is to be used outdoors, a weatherproof housing is recommended. The operating instructions for our duct sensor also include a drilling template for installation.
