Thermocouple Sensor System
for high-voltage applications
Thermo Sensor has developed a unique thermocouple sensor system which is designed specifically for applications in high-voltage areas. It consists of a mounting jack and the correspondent connector with a moulded thermocouple.
Due to the system purpose-built design, all components offer protection against high-voltage for up to 6 kV. Furhermore, all contacts and conductor materials are made of class 1 thermocouple material type K, which makes the system especially suitable for temperature measurement.
The correct polarity of the connection is assured by correspondent guidance bars in both plug and jack. A safety clip prevents accidental disconnection. Two insulated thermocouple wires are inserted in the jack, which can be connected to the electronic control unit.
The plug will be delivered with a moulded temperature probe. Generally, this would be a wire probe. Available are various diameters and insulations (e.g. Teflon or Kapton), depending on the stipulated withstand voltage. Additionally, a version with a moulded-on mineral-insulated thermocouple is also available (with a diameter of up to 3.0 mm), but in this case the withstand voltage is limited.
Both parts, plug and jack, can be sealed with caps while disconnected, so the protection of IP 67 is always guaranteed.
