Temperature probes
Temperature probes
Temperature probes are used whenever temperatures need to be recorded, monitored, controlled, or regulated. Depending on the type of temperature probe, some of them are also suitable for high-temperature applications.
How temperature probes work
The temperature sensor is a general component of the temperature probe, which basically detects and monitors temperature changes in the environment, materials, gases, and liquids and transmits this information to systems such as measuring devices, computers, or other monitoring systems. Temperature probes are in constant contact with the medium to be measured (invasive measurement). In addition to invasive temperature probes, there are also contact probes. Since these only touch the medium, they have no direct contact, making this a non-invasive method. In this way, for example, the flow in the pipe is not affected. Although the non-invasive method has various advantages, the measurement is less accurate because there is no direct contact with the medium itself. For this reason, contact or surface probes are often used for monitoring purposes only. Furthermore, the ambient temperature also plays a relevant role with contact probes, so that the surface/contact probes should have sufficient shielding or insulation. In addition, infrared devices or pyrometers can be used for surface measurement.
Since the sheath probe is made of highly resistant, mineral-insulated stainless steel cable, it is ideal for high temperatures.
Outdoor probe
B+B outdoor probes are ideal for measuring temperatures outdoors. The outdoor probes are available with Pt100 sensors, Pt1000 sensors, NTC sensors, and KTY sensors. Theseprobes are mainly used in building technology, heating technology, refrigeration technology, air conditioning technology, mechanical and plant engineering, and for general outdoor temperature monitoring. The outdoor probes are housed in a white plastic casing, making them very robust. The bayonet probe from B+B is also available with a Pt100 sensor. It is ideal for installation in blind holes, which are mainly found in the plastics industry.
Screw-in probes
B+B screw-in probes are primarily used for temperature measurement in liquid and gaseous media. These measurements are used in heating technology, air conditioning technology, ventilation technology, mechanical engineering, plant engineering, apparatus engineering, temperature monitoring of pipes or containers, and the chemical and petrochemical industries. The screw-in probes are available with a wide variety of sensors, e.g., DS18S20, Pt100, Pt1000, as well as with thermocouples of types K, J, and N.
Penetration probes
The B+B penetration probe is also available with thermocouple types K, J, and N. It can be used both as a core temperature sensor and as an immersion sensor. The insertion sleeve is very stable thanks to the high-quality stainless steel, which means that the sensor can be used not only in industry but also in the food sector.
Gas probes
But chimney sweeps also need modern technology to be able to carefully clean and inspect heating systems and stoves. B+B gas sampling probes are ideal for combined temperature, gas, and pressure measurement. Thanks to the type K mineral insulated thermocouple used, the probe measures core flow temperatures up to 800 °C. Such gas probes are also used in every car/truck TÜV inspection to measure exhaust emissions.
Cable probes
The range of B+B cable temperature probes is wide, so that everyone can find the right temperature probe for their individual applications. Whether for liquid, gaseous, or solid media, you will find the right cable probe here, depending on the design. The cable probes are equipped with Pt100, Pt1000, KTY, DS18S20, and NTC sensors. Their areas of application are wide-ranging, from heating technology to air conditioning, refrigeration, solar systems, heat pumps, white goods, and plant engineering.
Core temperature probe
The molded handles of the core temperature probes make them particularly robust and water vapor-tight. They are available with Pt100 sensors, Pt1000 sensors, and type K thermocouples. The handles and measuring tips are available in a wide variety of designs. The B+B air probes NiCr-Ni thermocouple type K and insulated variants are characterized by fast response times, as they have an exposed measuring tip.
Mineral insulated thermocouples
Mineral insulated thermocouples with B+B standard plug type K or B+B miniature plug type K enable short response times. The same applies to the design of the mineral insulated thermocouples (MIT) with the high-quality FEP silicone compensation cable. Due to their properties, mineral insulated thermocouples are used in chemical plants, power stations, pipelines, engine construction, and on test benches.
Surface probes
Surface probes are also available in various designs. Surface probes with type K sensor elements ensure temperature monitoring and control of surfaces. The surface probe with type K magnetic sensor is used for high-temperature measurement of metallic surfaces. Surface probes are used in the plastics industry (temperature control of tools), in mechanical and plant engineering, in the packaging industry, in infrared measurement systems, in quality assurance, and in incoming goods inspection.
Temeperature probe for pipes and pipe clip-on probes
Probes for pipes and pipe clip-on probes are used for simple indirect temperature measurement of pipes. These are available with Pt100, Pt1000, NTC, and KTY sensors. The pipe clip-on probes are available in a wide range of diameters, covering almost every pipe diameter. The simple clip mounting system simplifies commissioning and saves installation and service costs.
Temperature probes with connection head
B+B temperature probes with connection heads are available in numerous designs. The BINOX temperature probes with connection heads are specially manufactured for food technology, as they have virtually no dirt-trapping edges and are therefore even more hygienic. The MA temperature probe with connection head is used in heating, air conditioning, and ventilation technology, as well as in mechanical and plant engineering. Its robust and vibration-resistant design is characterized by its high tightness and high-quality stainless steel.
Temperature indicating stripes
We also sell irreversible temperature indicating strips for different temperature ranges. These are suitable for numerous applications in research, industry, and logistics, as they represent a cost-effective alternative to expensive measurement technology.
Depending on the model, our outdoor sensors feature a high-quality plastic housing with IP protection class IP 54 or IP 65.
We generally offer three different versions of the outdoor sensor. Firstly, there are the temperature/humidity sensors with item numbers beginning with FF-GLT-. We also offer a special outdoor temperature sensor that features a wide variety of sensors and is easy to mount on the wall. Furthermore, there is the new GLT series (building management technology series) with item numbers beginning with 0551. These are available from B+B both as temperature sensors and as sensors for the combined measurement variables of temperature and humidity. Outdoor sensors from the new GLT series Reliable and precise temperature and humidity sensors are required in industrial and building automation. The B+B outdoor sensor from the GLT series meets this requirement and is available in different versions: 0-10 volts or 4-20 mA (two-wire technology) are available as output signals for the measured temperature or temperature and humidity. In addition, the outdoor sensors are also available with a paper white display. The sintered filter mounted on the sensor tip provides optimum protection for the sensitive sensor technology, ensuring that the B+B outdoor sensor functions reliably even in harsh environmental conditions.
At B+B, you will find sheathed thermocouples with free ends, miniature plugs, standard plugs, Lemo couplings and silicone cables. Customised designs are available at any time.
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.
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.
Mineral insulated thermocouples are temperature sensors in which two different thermowires are embedded in a metal sheath. The wires are electrically insulated by compacted magnesium oxide and connected to each other at the measuring tip. Thanks to their robust, flexible design, mineral insulated thermocouples are bendable, vibration-resistant and suitable for high temperatures. The measuring principle of thermocouples is based on the Seebeck effect, in which a temperature-dependent thermoelectric voltage is generated at the junction of two different metals. This voltage is measured and converted into the corresponding temperature.
Thanks to their special measuring tip, bayonet probes are particularly suitable for use in flat and pointed boreholes. The dimensionally stable pressure spring ensures constant contact pressure of the measuring tip in the borehole and also serves as cable kink protection. This temperature sensor is mainly used in the plastics industry. Of course, our B+B bayonet probes are also available in other, customer-specific designs.
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.
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.
We offer different sensors and various diameters. We also sell matching accessories such as bayonet caps, bayonet springs and screw-in nipples.
