Our PPL13-T mineral insulated thermocouple is similar to our PPL1 style sensor but due to its construction is suitable for higher temperature applications. It is suitable for the measurement of liquids and gases across a wide temperature range. All sensors are made to order so it is generally possible to meet all of your requirements.
The plain stem of the probe is made from your choice of material which includes various grades of Stainless Steel (321, 310, 316), Inconel 600 or Nicrobell. The tip is TIG welded closed to give a pressure tight housing for the sensor. Mineral insulated thermocouples are available with very small diameter sheaths to give extremely fast response. Many metric and imperial probe diameters are available from 0.5mm upwards.
Mineral Insulated Thermocouple Construction
One of the main advantages of the mineral insulated construction is the flexibility of the probe stem which means that it can easily be shaped on site to fit you application, perhaps to fit around the inside wall of an oven. There is also greater flexibility on the length on the probe over the fabricated styles. Probes of many metres long are commonly manufactured and these are supplied coiled for easy transportation.
We stock a range of cables for use in our sensor manufacturing from low cost PVC to high performance PTFE (Teflon) and high temperature glass fibre insulations. We can cover almost any requirement whether this is low or high temperature or other environmental considerations such as moisture ingress protection or protection against corrosive substances.
