The electromechanical temperature controller manufactured by Leitenberger Mess- und Regeltechnik GmbH offers a combination of robust design and precise temperature regulation. This device is specifically designed for front panel installation and is made of polished stainless steel, featuring a 3-hole mounting flange that guarantees simple and secure installation. The device is an ideal choice for industrial and commercial applications where reliable, mechanical-based temperature monitoring and switching functionality are required.
This model utilizes the classic, bimetal-free Bourdon tube spring measuring system, ensuring durability and long-term reliability.
The temperature controller is ideally suited for the precise monitoring of temperature parameters and the control of switching functions, especially in systems where the reliability of mechanical solutions is preferred over digital ones.
Robust Design: The device housing is made of stainless steel, which provides excellent resistance against corrosion and mechanical stress.
Egyszerű Telepítés: Front panel mounting is facilitated by the polished stainless steel 3-hole mounting flange, ensuring a solid and aesthetically pleasing fixture.
Clear Readout: The display has a white background and black printing. The measured current value is shown in black, while the set target value is highlighted in red, maximizing readability.
High Accuracy: The display accuracy is classified in accuracy class 2 according to the DIN 16203 standard, which guarantees reliable measurement.
Versatile Temperature Range: The measuring range covers a wide scale, from -80°C up to +380°C, and can be customized according to specific customer requirements.
The following table summarizes the critical technical parameters of the temperature controller:

During the design of the device, the special requirements of different industrial environments were taken into account:
Handling Inductive Loads: When switching inductive loads, sparking and contact degradation can occur. To prevent this, the use of RC elements (RC-element) is recommended for spark quenching and contact protection.
Switching Function: The thermostat is equipped with a single-pole changeover contact, which can be freely set within the entire measuring range. This provides flexibility in the control logic.
Supplementary Protection: If further protection is required for the terminals, the IP 00 protection can be increased to IP 55 using an optional protective cap, in accordance with the DIN 60529 standard.
Leitenberger products offer maximum flexibility to adapt to user requirements:
Custom Measuring Range: It is possible to fully customize the measuring range according to the customer's specific temperature requirements.
Pre-set Switching Points: Certain versions are available with pre-set switching points, which prevent on-site adjustment, thus ensuring continuous, unaltered operation.
Locking the Maximum Set Value: Optionally, a mechanical stop is available to fix the maximum set value, preventing accidental or unauthorized modification of the setting.
For precise measurement and reliable operation, high-quality accessories are also available for the thermostat, especially for the temperature sensing elements (capillaries):
Stainless Steel Capillaries (Naked): Extremely durable capillaries equipped with a naked stainless steel sheath.
Copper Capillaries – With Single Copper Braid: Copper capillaries reinforced with a copper braid to increase mechanical protection.
Copper Capillaries – With Double Copper Braid: Copper capillaries with maximum mechanical protection, featuring double copper braid shielding.
Copper Capillaries with PVC Coating: Copper capillaries featuring an external PVC coating for additional insulation and protection.
This electromechanical temperature controller represents the „Made in Germany” quality, providing a reliable and long-lasting solution for temperature control tasks.
