This detailed product description refers to the surface-mountable thermometer with bimetal compensation and back plate, manufactured by Leitenberger MRT. This measuring instrument is excellently suited for industrial and refrigeration technology applications where reliable and accurate temperature measurement is required. The „Made in Germany” quality guarantees long service life and precise operation.
This bimetallic thermometer is used for temperature measurement and operates on the bimetallic principle, ensuring reliable operation and accurate measurement. The device is specifically designed for surface mounting, supplemented with a back plate for stable installation.
Basic Features:
Design: Metal casing, light grey color, with plastic coating.
Window: Glass (for type 1100 HBR, MAKROLON® type, which is a highly resistant plastic).
Front Plate/Bezel: Chrome-plated front plate for durability and aesthetics.
Operating Principle: Equipped with bimetallic compensation.
Accuracy: Default accuracy class: $pm 2 %$.
Manufacture: Quality „Made in Germany”.
The thermometer is available in various sizes and designs, which can be selected depending on the measuring range and installation requirements. The table below summarizes the physical dimensions of the different types (1060 HBR, 1080 HBR, 1100 HBR, 1160 HBR):
| Típus | a (mm) | b (mm) | c (mm) | d (mm) | D (mm) | I (mm) | L (mm) |
|---|---|---|---|---|---|---|---|
| 1060 HBR | 36 | 0,9 | 4 | 64 | 86 | 3,6 | 75 |
| 1080 HBR | 38 | 0,9 | 4 | 84 | 110 | 3,6 | 95 |
| 1100 HBR | 38 | 1,5 | 8 | 105 | 132 | 4,5 | 116 |
| 1160 HBR | 47 | 6 | – | 160 | 196 | 5,8 | 178 |
Note: The letters in the table above denote the various dimensions of the instrument (e.g., D: case diameter, L: probe length or total length, depending on installation dimensions).
In addition to the standard design, numerous options are available to maximize adaptation to user requirements:
Back Adjustment: Allows fine-tuning of the instrument via the back, which can be particularly useful for installations in confined spaces.
Increased Accuracy: Available instead of the standard $pm 2 %$ accuracy:
$pm 1 %$ accuracy
$pm 1.5 %$ accuracy
Drag Pointer: An auxiliary indicator that records the maximum or minimum measured value, helping to track temperature fluctuations.
Custom Scale and Dial: Possibility to customize the dial, including colored scales or specific markings that optimize readability for the respective application.
Plexiglass (Plexiglass): Use of plexiglass (acrylic) instead of the standard glass window, offering a more impact-resistant solution.
Case Color: A black case is also available instead of the standard light grey.
Bimetallic compensated thermometers are versatile and can be used in many applications, especially where the temperature needs to be checked on a surface or near a pipe. Typical areas of use:
Refrigeration technology: Surface temperature monitoring of cooling units and air conditioning systems.
Industrial Measurement and Control Technology: Monitoring of general industrial process temperatures.
Heating and Air Conditioning Systems: Measurement of surface temperature on boilers, pipes, or air ducts.
The bimetallic compensation is a crucial function of this thermometer. Since bimetallic strips are sensitive to ambient temperature, the compensating element ensures that the instrument accurately measures the temperature of the surface being measured, regardless of changes in the ambient temperature. This technology increases measurement accuracy in case of ambient temperature fluctuations around the instrument housing.
Leitenberger offers a wide portfolio of accessories that can optimize the installation and use of the thermometer. These include:
Flexible Capillary Tubes: Capillaries of different materials and designs (stainless steel, copper, copper with PVC coating) are available for the connection between the thermometer and the measuring point.
Stainless Steel (V-Stahl)
Copper – Single copper braided (CU- single cooper braided)
Copper – Double copper braided (Cu- double copper braided)
Copper – PVC coated (Cu-PVC coated)
Temperature Probes (Probes): Different types of probes (type 1, type 2, type 3, type 4, type 5, type 6, type 7c, type 7.1) are available to satisfy various installation and heat transfer requirements.
Installation Pockets (Pockets): Stainless steel (No. 9) or other material installation pockets (No. 8) for safe installation into the pipeline.
This metal plate case bimetallic thermometer combines the reliability of Leitenberger with flexible customization, making it an ideal choice for professional temperature monitoring tasks.
