This detailed product description applies to the Leitenberger item number 02.49, a steel-cased thermometer for surface mounting, equipped with a rear flange, which bimetallic without compensation is manufactured. The product is born under the sign of German precision and quality (Quality made in Germany), ideal for industrial and refrigeration technology applications where reliable surface temperature measurement is required.
This robustly designed analog thermometer is excellently suited for environments where the temperature needs to be measured directly on a surface, and the instrument must be fastened from the back using a flange. The absence of bimetallic compensation ensures simpler, yet extremely reliable operation within the specified measuring range.
The main features of the device are as follows:
Design: Thermometer designed for surface mounting, equipped with a rear flange.
Measuring principle: Based on the bimetallic principle, but this specific model does not have bimetallic compensation.
Accuracy: The measurement accuracy is ± 3%.
Casing: Made of steel, coated in light grey plastic, which provides excellent mechanical protection and corrosion resistance.
Window: Made of durable glass (Type 1100 HBR/fs MAKROLON), which resists environmental influences.
Front Plate/Bezel: A chromed front ring ensures a professional appearance and easy readability.
Adjustment: Rear adjustment possibility (back adjustment).
The thermometer is available in three different sizes, which differ in installation depth and scale diameter. The table below details the specifications for the various types:
| Típus | a (Installation depth, mm) | b (Wall thickness, mm) | c (Mounting hole diameter, mm) | d (Distance between mounting holes, mm) | D (Case diameter, mm) | I (Sensing element diameter, mm) | L (Sensing element length, mm) |
|---|---|---|---|---|---|---|---|
| 1060 HBR/fs | 26 | 0,9 | 4 | 64 | 86 | 3,6 | 75 |
| 1080 HBR/fs | 26 | 0,9 | 4 | 84 | 110 | 3,6 | 95 |
| 1100 HBR/fs | 28 | 0,9 | 8 | 105 | 132 | 4,5 | 116 |
Part number: 02.49 (Without bimetallic compensation)
In addition to the standard version, Leitenberger offers several customization options to meet individual requirements:
Custom Scale: It is possible to create custom scales, including color markings or zones that visually highlight critical temperature ranges.
Plexiglass: Instead of standard glass, a plastic glass (MAKROLON) window can be selected, which provides greater impact resistance.
Case Color: The casing is also available in black instead of the standard light gray plastic coating.
This type of thermometer is an ideal choice for industrial and commercial systems where accurate and continuous surface temperature monitoring is essential:
Refrigeration technology: Monitoring the surface temperature of cold rooms, cold storage units, and climate control equipment.
Industrial Mechanical Engineering: Continuous surface monitoring of machines, equipment, and pipelines.
Heating and Air Conditioning Systems: Temperature measurement of the outer surfaces of boilers, heat exchangers, and air ducts.
General Industrial Environments: A reliable, mechanical thermometer that does not require an external power source.
For precise measurement and proper installation, users often purchase the following accessories for the type 02.49 thermometer:
The capillary tube of the appropriate length and material is essential for the operation of the thermometer.
Capillary Stainless Steel (Naked): Natural stainless steel version.
Capillary Copper – Single Braid: Made of copper, equipped with a single layer of braided protection.
Capillary Copper – Double Braid: Made of copper, equipped with double copper braiding for increased mechanical protection.
Capillary Copper – With PVC Coating: Copper capillary with an external PVC coating for additional protection and insulation.
The accuracy and method of measurement are influenced by the design of the probe. For various installation and application requirements:
Type 1 Probes (1a, 1b, 1c): Basic probe designs.
Type 2 Probes (2a, 2b, 2c): Sensors with a more specialized geometry.
Type 3 Probes (3a, 3b, 3c): Further variations for installation conditions.
Type 4 Probes (4a, 4b, 4c): Sensors with custom design.
Type 5 Probes (5a, 5b, 5c): Probes ensuring special heat transfer.
Type 6 Probe (6a): Custom probe type.
Type 7c Probe: Special version.
Type 7.1 Probe: Further variation.
Serve to protect the temperature sensor and for installation into pressurized systems:
Type 8 (No. 8): Standard protective sleeve.
Type 9 (No. 9): Alternative protective sleeve design.
This Leitenberger thermometer offers reliability, German manufacturing quality, and a simple yet effective solution for surface temperature measurement for industrial users.
