Thermistors Probes

It exists two kinds of thermistors : NTC and PTC (see these headings for technical information) For the temperature probes it's generally a NTC thermistor which is used. In such case American are preferred for their accuracy and long term stability These sensors are frequently welded at the end of leads or cables, with or without a shield, depending of use.

Then the sensor and the end of the leads are encapsulated in a housing made of different materials and with various shapes (mainly boxes or tubes), in accordance with the needs, in order to protect the sensitive part against dusts, moisture, shocks. Boxes are made eiyher of plastics : PVC, ABS, Polycarbonates, or in metal (steel, stainless steel, aluminium or other). Tubes are either in metal : stainless steel, tinner copper, nickel platted copper, brass, bronze, anodises aluminium, or in plastics : PVC, Silicone, Teflon, Vinyl, Polycarbonate, etc. Leads and cables can be insulated with PVC, Silicone, Teflon, Polyurethane, Vinyl, Isomid, Kynar, Glass, Silk Jacket, etc. Lenghts are comprised between some centimetres and several tens of meters. The other end of cables can be stripped, stripped and tinned, fifted with fast-on or connectors. All kind of probes are customs designed.
