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.

Can B+B produce customised items?

Yes, customised designs are available on request. Please note that due to the planning and implementation costs involved, we can only produce customised designs for orders with a minimum value of €500.00.

Where do you use exhaust gas probes?

Exhaust gas probes are used for monitoring and control in heating technology, buildings, industrial plants, combustion plants, vehicles and large vehicles such as tanks to monitor emissions and ensure efficiency and safety. They help to monitor compliance with environmental regulations and increase safety by controlling exhaust gases.

What are the special features of the flue gas probes from B+B?

B+B offers probes with a heated pistol grip. This heating reduces condensation. The handle also has a soot filter holder. B+B also sells probes for combustion plants (1. BImSchV), multi-hole probes and special probes for exhaust gas measurements on large vehicles, e.g. lorries, buses and tanks.

What are the key feastures of the flue gas probes?

The Firebird TGD flue gas probe has a screw-off coaxial probe tube, separate gas/pressure paths, a stainless steel protective tube and a moulded handle. The Eco TGD flue gas probe also has a moulded handle and impresses with its fast response time. In addition, a slotted hole is visible on the measuring tip. The Sigma flue gas probe, on the other hand, differs in particular in its heated handle, optional screw-off probe tube and R6 soot filter holder.

What delivery methods are available?

Shipping is generally handled by DPD.

Is there a minimum order quantity?

As a logged-in user, your data and shopping basket are stored in your customer account and will be available to you the next time you log in. However, items will be automatically removed after 2 months.

Error message regarding VAT during registration

When registering in the B2B shop, an automatic query of the VAT ID is run in the background on the server of the Federal Central Tax Office in order to validate it. Unfortunately, this server is often unavailable, which is why you receive the error message ‘VAT number ID invalid’. Please contact us directly or wait a few minutes until the server is available again.

Do I have to register as a user to place an order in the B+B online shop?

Yes, it is always best to register. This allows you to view your orders and payment options, as well as add orders back to your shopping basket with a single click. You will then have a comprehensive overview of your account and your orders.

Not every company allows orders to be placed via the online shop. What options are available?

You can place an order in the following ways:by Fax: +49 (0)771 8316-50 by E-mail: info@bb-sensors.com

An item needs to have a ‘neutral’ or ‘personalised’ label. Is that possible?

Please enquire directly with us regarding this matter.

What types of accessories does B+B supply?

Our range of accessories can be divided into three categories: cables, turned parts, and other accessories. The latter category, "other accessories," in particular, offers a wide range of product groups. Here, we offer, for example, plastic housings, wall mounts, and (sintered) filters.

Where are the turned parts being manufactured?

Most of the turned parts are manufactured at our site in Donaueschingen (Germany).

Out of what materials are the turned parts made of?

The material may also vary depending on the turned part. We offer a wide selection ranging from various stainless steels to brass. You can find the materials in the specification tables for the respective items.

Can B+B produce customised items?

What is the accuracy of the FLW-122?

The FLW-122 achieves an accuracy of <3% of the measured value. However, this is highly dependent on the evaluation electronics used.

Which flow sensors is the module compatible with?

The module is compatible with FS5/7 and OOL flow sensors.

Which parameters are recorded for air quality measurement?

Air quality measurements primarily record pollutants such as particulate matter, nitrogen dioxide, ozone, carbon monoxide, sulphur dioxide and volatile organic compounds (VOCs), as well as climatic parameters such as temperature, humidity and CO₂ concentration, in order to assess both outdoor and indoor air quality.

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.

Can B+B produce customised items?

Yes, customised designs are available on request. Please note that due to the planning and implementation costs involved, we can only produce customised designs for orders with a minimum value of €500.00.

Which protective filter is used with the duct sensor?

The humidity sensor comes with a 25 µm PE sintered filter as standard. Other filters and special hydrophobic filters are of course available as optional accessories.

What types of duct sensors are available from B+B?

The channel sensors can be individually configured using three different components: the measured variable (temperature, temperature and humidity), the output signal (0...10 V or 4...20 mA) and the version with or without display.

What are duct sensors and what are they used for?

Duct sensors have been specially developed for installation in ventilation or air conditioning ducts. They measure the air temperature and/or humidity directly in the air flow, thus providing precise data for control and monitoring systems.
