Screw-in and weld-in protective sheaths

Screw-in protective sheaths are used for installing thermocouples and resistance thermometers in cases where it is necessary to exchange the thermometer without emptying the system. Screw-in protective sheaths are used in places where there is high pressure or high flow speeds and standard thermometers cannot be used. The maximum pressure sealable via the thread depends on the installation conditions.

Plugs and couplings

Connectors (plugs, couplings) are used for thermocouple and resistance thermometers connectors or to directly connect evaluation units. Many different versions of thermocouple plug connectors are available.The advantage of this contact arises from the respective thermocouple or extension material. The variations in connectors for resistance thermometers are almost inexhaustible.

Head- and rail-mounted transmitter

Electric thermometers have only a weak, sensitive output signal. Temperature transmitters transform it, for example, into a standard, temperature-proportional current signal, which can also be transmitted over long distances interference-free.

Dual-wire transmitters draw the required energy from the circuit.

The remaining output energy of 4 to 20 mA corresponds to the measuring signal and is always temperature-linear. 

Slot resistance thermometers

Slot resistance thermometers (SRT) are electric temperature probes for temperature monitoring of the winding temperature of electric motors or generators.

Thanks to their long and narrow shape, these thermometers are ideal for installing into the slot of the startor/rotor directly in the winder.

An extremely wide range of different measurements can be produced. This allows the thermometer to be best adapted to the different slot sizes. Directly installing the thermometer into the slot makes it possible to achieve an almost optimal measuring accuracy.

Sheathed thermocouples

Sheathed thermocouples permit very small bending radii and are generally used for difficult-to-access measuring locations. The thermo-wires are embedded in a compressed oxide powder in a mineral insulated sheath, making them resistant to vibrations. The measured values are thus not influenced by bending or by strong vibrations.

Screw-In Resistance Thermometers EN

This group of screw-in resistance thermometers comprises very many versions of thermometers in various housings. They range from simple screw-in housings with wires attached via permanently fixed screw connections or adjustable clamping connections, to a range of connection heads with protective fittings and various process connections. Fixed or adjustable screw fittings allow the resistance thermometers to be individually adapted to the individual fitting position and quickly and easily assembled.

Special models with a measuring range of up to +850°C are also available. 

Screw-in thermocouples

Thermocouples are widely used as active sensors in measurement and control technology, due to their being available in almost any kind of shape. They can measure a very wide range of temperatures, from -200°C up to +1200°C (with the corresponding protective tube and thermocouple pairing up to 2300°C) and are therefore commonly used in plant, mechanical and equipment engineering and also to determine the temperature of molten salt and metal.

Cable thermocouples

Cable thermocouples can be built to be very small and are generally used for difficult-to-access measuring locations. Manufactured with shrink hose or metal sheath, these temperature sensors are frequently used to handle a broad range of temperature measurement tasks. Their application area is primarily in the lower to mid temperature range from -70°C to 200°C.

Special versions with a working temperature of up to 400°C can also be supplied.
