# Electromechanical Temperature Controller \u2013 SQUARE DESIGN (Without bimetallic compensation)<\/p>\n
The electromechanical temperature controller manufactured by Leitenberger (type number: 04.74) represents a combination of robust design and extremely precise temperature control. This instrument is an ideal choice for industrial applications requiring reliable and accurate temperature monitoring, especially in the fields of refrigeration technology and industrial measurement technology.<\/p>\n
The device is made of high-quality stainless steel and features a transparent glass front panel, ensuring durability and easy readability. The \u201eMade in Germany\u201d quality guarantees a long service life and reliable operation, in compliance with the strict requirements of DIN EN ISO 9001 quality standards.<\/p>\n
## Main Features and Advantages<\/p>\n
This remote signaling thermostat is built upon a Bourdon tube measuring system and operates specifically **without bimetallic compensation**, which can be advantageous in certain applications due to its simpler structure and specific measuring ranges.<\/p>\n
### Precise Measurement and Control<\/p>\n
The device is used for measuring temperature and for switching relative to a set value. Thanks to the user-friendly design, adjustments can be made easily, while the display is extremely informative.<\/p>\n
* **Measuring System:** Dual Bourdon tube measuring system, without bimetallic compensation.
\n* **Display:** The momentary temperature value is shown with a black indicator, while the set switching point (setpoint) is displayed with a red indicator. This high-contrast presentation significantly facilitates the quick assessment of the current status.
\n* **Scale Length:** An approximate 240\u00b0 scale length ensures fine resolution. The scale division is variable (1\u00b0, 2\u00b0, 5\u00b0, 10\u00b0), depending on the selected measuring range.
\n* **Accuracy Class:** The measurement accuracy is classified in **Class 2 according to the EN 16203 standard**, guaranteeing reliable industrial precision.<\/p>\n
### Switching Functions<\/p>\n
The temperature controller has an integrated electrical switch, which enables the control of external systems (e.g., heating or cooling units) when the set temperature is reached.<\/p>\n
* **Switch Type:** Single-pole changeover contact.
\n* **Adjustment Option:** The switching point can be set within the entire measuring range. The adjustment is made using a prominent, PVC-made rotary knob.
\n* **Switching Capacity:** 5A \/ 3A at 125 \/ 250 VAC, at a frequency of 40\u201360 Hz.
\n* **Switching Hysteresis:** Following the attainment of the switching point, the accuracy of the reconnection is as follows:
\n* On temperature decrease: +2%
\n* On temperature increase: -2%<\/p>\n
### Mechanical Design and Protection<\/p>\n
The device design ensures maximum durability and flexibility during installation.<\/p>\n
* **Mounting:** Done from the rear using a mounting clamp.
\n* **Housing Protection:** The instrument housing complies with the **IP 53** protection class according to the DIN 60529 standard. This ensures protection against dust ingress and protection against splashing water.
\n* **Terminal Protection:** The default protection for the connectors (terminals) is **IP 00**.
\n* **Optional Protection:** Using an optional protective cap, the protection for the connectors can be increased to **IP 55**, which offers enhanced protection against dust and water jets.<\/p>\n
