Thermocouples & Resistance Thermometers
General information
Thermocouples for the plastics industry generally feature bayonet connectors in various designs. The thermocouples are inserted directly into the injection moulding and extrusion media, or mounted on heating bands, in heating systems or on specific machine components. The thermocouples are also used for surface temperature monitoring.
Thermocouples consist of two different metals joined together at one end. Due to the so-called Seebeck effect, a voltage is generated when there is a temperature difference along the conductor, which serves as the measured variable.
Sheath thermocouples are designed for use in environments with temperatures up to a maximum of +1200 °C (on request).
Resistance thermometers are based on the change in the electrical resistance of metals as the temperature rises. Not every metal is suitable for the manufacture of resistance thermometers; in most cases, platinum is used as the conductor.
The commonly used Pt 100 sensor has a resistance of 100 ohms at a temperature of 0 °C.
Specifications
Resistance thermometers are manufactured with Pt 100 sensors in Class A or B in accordance with EN 60751.
Thermocouples can be manufactured with Type K, J or L thermocouples in Class 1 or 2 in accordance with EN 60584 or DIN 43710.
Designs: for insertion, screw-in, screw-on or clamping
Standard glass fibre connection cable with stainless steel wire braiding or Teflon connection cable and corresponding compensation cable
Custom designs are available on request, particularly with regard to optimised heat-conducting tips and thermally decoupled sensor tube sections.
EMC Directive 2004/108/EC
According to this directive, resistance thermometers and thermocouples without transmitters are basic components to which the directive does not apply.
CE marking and conformity assessment is not permitted.
