This detailed product description presents the Leitenberger thermometer, article number MRT 02.03, with bimetallic compensation, designed for front panel installation in a sheet metal casing, specifically engineered for industrial and refrigeration applications. Excellent German quality (Made in Germany) guarantees reliability and a long service life.
This robustly designed thermometer is the ideal solution for situations requiring precise temperature measurement where the instrument must be integrated into a panel or enclosure. The 3-hole front flange ensures stable and secure mounting. The bimetallic compensation technology guarantees reliable operation even against environmental temperature fluctuations.
Part number: 02.03 (With Bimetallic Compensation)
Compensation: Equipped with bimetallic compensation, which ensures the maintenance of measurement accuracy even in the event of temperature changes in the instrument's environment.
Accuracy: Default accuracy class: $pm 2%$.
Tok (Ház): Corrosion-protected steel sheet (Steel sheet corrosion protected).
Window (Lens): Glass (For Type 1100 F: MAKROLON®).
Front Flange: Available in polished INOX (stainless steel) or chrome-plated finish.
The thermometer offers numerous customization options to meet the most diverse measurement requirements.
In addition to the standard accuracy of $pm 2%$, the following options are also available:
Back adjustment: Allows for calibration or fine-tuning of the instrument from the rear side.
Enhanced Accuracy: Available on special order in accuracy classes $pm 1%$ or $pm 1.5%$.
Drag pointer: An additional indicator that shows the maximum or minimum measured value and can be manually reset.
Custom Scale: Possibility to create custom dials and colored scales according to the application's specific requirements.
Plexiglass: The use of acrylic glass (MAKROLON) instead of standard glass is possible on certain types (e.g., 1100 F), ensuring greater impact resistance.
The thermometer is available in various sizes and designs, detailed in the table below. The designations in the table specify the geometric dimensions of the instrument in millimeters (mm).
| Típus | a (Mounting size) | b (Flange width) | c (Flange thickness) | d (Thermowell diameter) | D (Casing diameter) | I (Installation depth) | L (Total length) |
|---|---|---|---|---|---|---|---|
| 1052 F | 25 | 9 | 0,5 | 52 | 80 | 4,2 | 74 |
| 1060 F | 25 | 9 | 0,5 | 60 | 80 | 4,2 | 74 |
| 1080 F | 22 | 12 | 0,5 | 80 | 105 | 4,2 | 96 |
| 1100 F | 30 | 8 | 0,75 | 102 | 132 | 4,5 | 116 |
| 1160 F | 45 | 3,5 | 3 | 160 | 192 | 5,8 | 178 |
Note: The parameter ‘a’ in the table indicates the mounting distance of the 3-hole front flange, ‘D’ is the instrument's outer diameter, while ‘L’ indicates the total length.
The 02.03 type thermometer is excellently applicable for:
Refrigeration technology: Pressure and temperature monitoring of air conditioning systems, chiller units, and cooling coils.
Industrial Measurement and Control Technology: Temperature monitoring of production lines, boilers, and other large machinery where a robust, panel-integrated solution is advantageous.
Automotive Testing: Although primarily designed for industrial purposes, its massive construction makes it suitable for specialized automotive test environments as well.
To achieve the full functionality of the thermometer and the optimal positioning of the measuring point, Leitenberger offers a wide selection of accessories, which can be ordered separately:
Capillaries connecting the thermometer housing and the sensing element are available in various materials and designs:
Stainless Steel (V-Stahl): Natural design, exceptional durability.
Copper (Cooper) – Single Braid: Copper wire, with a single layer of braided protection.
Copper (Cu) – Double Braid: Copper wire, with enhanced mechanical protection.
Copper – PVC Coated (Cu-PVC coated): Provides additional protection against external environmental influences.
The accuracy of the measurement and the method of installation are determined by the probe type. The selection of the appropriate probe type is crucial for the 02.03 type thermometer (which operates on the bimetallic principle):
1. Type (Typ 1a, b, c): Probes with different designs.
Type 2 (Type 2a, b, c): Sensors with different geometry.
Type 3 (Type 3a, b, c): Third sensor category.
4. Type (Typ 4a, b, c): Fourth sensor configuration.
Type 5 (Typ 5a, b, c): Fifth sensor category.
Type 6 (Typ 6a): Special sensor.
Type 7c (Typ 7c) and Type 7.1 (Typ 7.1): Further special probes.
In addition, pocket-type sensors are also available (e.g., pocket no. 8, pocket no. 9), which serve as protective sleeves for temperature measurement.
The products of Leitenberger Mess- und Regeltechnik GmbH follow the principle of „quality made in Germany”, ensuring precise engineering work and long-term reliability even in the most demanding industrial environments.
