High Accuracy Pt100 Probe – 1/10 DIN 4 Wire

Our high accuracy Pt100 temperature sensor is ideal for use as a calibration reference sensor. We use a 1/10 DIN sensing element within the probe which has an accuracy of +/-0.03°C at a temperature of 0°C and is available as either a 3mm diameter sensor or 6mm diameter. When using high accuracy sensors, depth of immersion is critical to ensuring measurements are as precise as possible. The sensing length of this sensor is 15mm so we recommend a minimum depth of immersion of 150mm.

We take great care during the assembly of these sensors and employ specialised techniques to ensure your sensor gives good service for an extended time. Careful treatment of the sensor housing and filling with inert media ensure that sensor drift is minimised.

The plain stem of the probe is made from 316 stainless steel and the tip is TIG welded closed to give a pressure tight housing for the sensor. We offer standard diameters of 3mm and 6mm in various standard lengths to suit your needs. The 3mm sensors have a pot seal to accommodate the cable.

The probe is fitted with 2 metres of high performance PTFE (Teflon) screened lead which is practically chemically inert and is suitable for the full operating range of the sensor. The plated copper braid screen provides mechanical protection as well as providing the opportunity for electrical screening should it be required. The silver plated copper conductors are very easy to solder, making fitting a connector extremely straightforward. If you prefer, we can do this for you – just ask!
