Cabos compensados – F.Fonseca
The compensated cables allow the correct connection of thermocouples and thermoresistences to the reading and control equipment.
The compensated cables are identified by the composition of the materials that constitute them. The most commonly used are type K, J, S, R, B, T and N. They can be distinguished by the color of the outer coating and F.Fonseca uses the IEC standard in the color coding of the cables that it sells. The compensated cables can be extension or compensation, according to the specific need. The outer coating may vary between the metallic braid, the PVC, the silicone, or the teflon.
F.Fonseca also provides cables for RTD's, which can be 2, 3, 4 or 6 wires. With the coating option vary between metal braid, silicone or Teflon.

Ceramic tubes and insulators - Sensor components – F.Fonseca
The ceramic tubes and insulators allow the protection and isolate the thermocouples and wires from the temperature sensors.
Ceramic tubes, from F.Fonseca, exhibit greater or lesser dynamic resistance depending on the amount of alumina used in their composition. The DIN 610 ceramic tubes contain 60% alumina in their composition and can be used at temperatures up to 1500°C. The DIN 799 ceramic tubes contain 99.7% alumina and can be used at temperatures up to 1800°C.
The DIN 799 tubes offer better shock resistance when compared to DIN 610.
In the insulators we have the same distinction of typology according to its composition. Insulators can have 1, 2 or 4 holes and their internal and external diameters are several depending on the thermocouples / wires to be used.

Industrial resistance thermometers MWD - Kobold
Industrial resistance thermometers according to DIN – MWD.
Kobold temperature assemblies comprise a rugged installation fitting made of stainless steel with thread, flange or weld-on process connection, a connection head and a measuring element. A Pt100 temperature sensor according to IEC 751, class A, B, 1/3 DIN or 1/10 is fitted in the measuring element.
On request, the measuring element can be removable, thus, allowing to remove the measuring element without interrupting the process as the customised thermowell remains in the installation and seals the process. Alternatively these sensors can be designed as a single or double resistance thermometers, except the 4-wire version, which can only be built with one Pt100 due to lack of space.

RTD – F.Fonseca Temperature Sensors
Thermoresistances, also known as RTD (Resistance Temperature Detectors), are temperature sensors made of high temperature coefficient electrical resistance metals.
RTD temperature sensors are typically identified by the material of which they are constituted and by the resistance they present at 0°C. The most commonly used nominal values are Pt100, Pt500 and Pt1000. The various rated values, output characteristic dependent on temperature and tolerances are specified in DIN EN 60751.
