TUC: Universal thermostat

Product catalog summary

Overview: The TUC Universal Thermostat is designed to regulate and monitor the temperature of liquids and air in various settings such as baths, containers, pipes, and ducts. It operates without auxiliary energy, enhancing energy efficiency.

Features:

Available in variants like Temperature Monitors (TW), Safety Temperature Monitors (STW), Temperature Limiters (TB), and Safety Temperature Limiters (STB).
Includes remote sensor, clamp-on, and capillary tube thermostats.
Complies with PED 97/23/EC (2014/68/EU) as category IV for certain models.
Temperature compensation minimizes shift in change-over point.
Supplied with a 100 mm thermowell.

Technical Data:

Power Supply: 230 V~, with specific load capacities for different terminals.
Adjustment Point: For ta 22 °C, with temperature effect at instrument head approximately -0.1 to -0.2 K/K.
Time Constants: Vary based on medium (water, oil, air) and presence of thermowell.
Ambient Conditions: Operating temperature range from 0 to 70 °C, storage from -25 to 80 °C.
Construction: Features plug-in connectors, specific cable cross-sections, and a two-section housing.

Standards and Directives:

Type of Protection: IP54 (EN 60529).
Protection Class: I (EN 60730).
Test Marks: TÜV ID:0000046121.

Types Overview: Various models are available with different setting ranges, switching differences, and maximum sensor temperatures. Specific models are designed for different applications and temperature ranges.

Accessories: Includes retaining holders, sensor cartridges, mounting plates, and more for versatile installation options.

Description of Operation: The thermostat uses a single-pole change-over switch activated by temperature changes. It includes setpoint adjustments and switching differences for precise control.

Definitions and Functions:

Temperature Monitor (TW): Automatic on/off switching based on set temperature.
Safety Temperature Monitor (STW): Similar to TW but switches to a safe state if a capillary tube breaks.
Temperature Limiter (TB): Requires tool for setpoint adjustment and manual reset.
Safety Temperature Limiter (STB): Similar to TB but includes safety features for broken capillary tubes.

Intended Use: The product is intended for specific applications as described and must adhere to all related regulations.

Technical Appendix: Provides details on switching point accuracy and RC circuitry for inductive loads.

Materials: Information on housing and thermowell materials, with operator responsibility for material compatibility.

Disposal: Disposal must comply with local laws, and the product is not considered dangerous under Directive 67/548/EEC.
