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.

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.

Temperature sensors with wireless technology – F.Fonseca

The need to measure temperature in remote or hard-to-reach places created the need to use wireless technology to overcome physical obstacles. By incorporating the Jumo Wtrans B transmitter into F.Fonseca sensors, we have brought down the physical barriers that have hitherto prevented the measurement of temperature in remote, moving or hard-to-reach places.
 
Using the 868.4 MHz transmission frequency the Jumo Wtrans B transmitter allows F.Fonseca  temperature sensors to integrate the transmitter and the antenna into the sensor itself. The programmable transmitter is universal and applicable in type B heads, having operating temperature between -30 ° to 85 ° C. The antenna with M20x1.5 connection will includes a 3.6V 2.2Ah lithium AA battery and has a maximum range of 300m in the open field.

Temperature Transmitter dTRANS T01- Jumo

The dTRANS T01 Temperature Transmitter is a universal transmitter (RTD and Thermocouple), galvanically isolated, with 4 to 20 mA output and HART interface. Programmable by software.

The 2-wire transmitter, from Jumo, senses the temperature by means of a RTD temperature probe or a thermocouple. For RTD temperature probes, the probe can be connected in a 2, 3 or wire circuit. The probe type, connection type, and measurement range can be configured using a configuration program. The 4 to 20 mA or inverted 20 to 4 mA output signal is provided linearized (temperature-linear). The device is designed for industrial applications and complies with the respective European standards for electromagnetic compatibility (EMC). For potentially explosive atmospheres we have the dTRANS T01 Ex complies with the directives concerning the explosive areas according to the declaration of conformity.
