New Metal Sample Temperature Sensor for Diesel Fuel Distillation

Introduction

Automatic distillation devices usually measure the sample temperature by using glass temperature probes.

These glass temperature probes are fragile, can break easily or may need a special (not standard-conform) protection. Handling these probes in the daily laboratory routines requires extremely careful treatment.

Having to replace a broken glass sensor causes annoying instrument down-time, costs money and invariably requires a validation procedure for the new sensor.

Even the cleaning procedure for the glass sensor after each measurement requires extreme care so as not to break the probe and may be complicated.

Therefore an unbreakable metal sensor is the perfect alternative - provided it is guaranteed that this sensor shows the same results as a glass sensor.

Such a comparison can be done by running the metal sample Pt100 with ILS samples.

The ASTM Proficiency Testing Program is a valuable tool for laboratories and instrument manufacturers worldwide to conduct equal tests on the same material in accordance with the same test method. ASTM evaluates the performance of the laboratories by arranging a statistical analysis of the results.

Participating in interlaboratory studies (ILS) organized by the German standardization body DIN, the European Standardization Committee EN for more than 20 years, or ASTM Proficiency testing program, ILS have a long history with Anton Paar.

To verify the precision of Anton Paar’s new metal sample temperature probe we have now compared the ILS average values for the diesel sample DF 22006 with the results of the metal Pt100.
