Ein Pt100 ist ein elektrischer Temperatursensor, der den elektrischen Widerstand von Platin nutzt, um Temperaturen zu messen. Bei 0 °C beträgt sein Widerstand exakt 100 Ohm, daher der Name: „Pt“ steht für Platin und „100“ für den Widerstand bei 0 °C. Pt100-Sensoren zeichnen sich durch hohe Genauigkeit und Stabilität aus und werden häufig in der Industrie eingesetzt.

Was versteht man unter Pt1000?

Ein Pt1000 ist ein Temperatursensor, der den elektrischen Widerstand von Platin zur Temperaturmessung nutzt. Bei 0 °C beträgt sein Widerstand genau 1000 Ohm. Der Name setzt sich aus dem chemischen Symbol für Platin („Pt“) und dem Widerstandswert bei 0 °C („1000“) zusammen. Pt1000-Sensoren sind für ihre hohe Genauigkeit und Stabilität bekannt und finden in vielen industriellen Anwendungen Verwendung.

Was ist der Unterschied zwischen Pt100 und Pt1000?

Beide sind Widerstandsthermometer, die den Widerstand von Platin zur Temperaturmessung nutzen. Der Hauptunterschied liegt im Nennwiderstand bei 0 °C: Der Pt100 hat 100 Ohm, während der Pt1000 einen höheren Widerstand von 1000 Ohm besitzt. Durch den höheren Widerstand bietet der Pt1000 eine bessere Auflösung bei der Messung von Temperaturänderungen.

Wer hat den Pt100 erfunden?

Der Schweizer Physiker Willy Jentzsch entwickelte 1927 den ersten Pt100 Sensor.

Harald Peters – Specialist author for temperature measurement technology

Brief profile

Harald Peters is a specialist author focusing on temperature measurement technology and industrial sensor technology.
For many years, he has been working intensively with resistance thermometers, in particular Pt100 and Pt1000 sensors, their physical principles, measurement accuracy, standardization, and practical application in industry and technology.

On pt100.de, he publishes in-depth technical articles, calculation aids, and technical explanations for engineers, technicians, trainees, and users in industrial practice.

Education

Harald Peters holds a degree in chemical process engineering.
His studies focused on inorganic, organic, and physical chemistry, measurement and control technology, thermal and mechanical process engineering, analytical methods, laboratory practice, and chemical reaction mechanisms.

This training formed the basis for professional activities ranging from chemical laboratories and chemical production plants to chemical plant engineering.

Professional career

After working in battery research at Varta Batterie AG and commissioning chemical production plants in Germany and abroad (Metallgesellschaft AG / Lurgi), Harald Peters has been involved in the development, manufacture, and sale of measuring and control devices for flow, temperature, pressure, and level since 1985 (including Kobold Messring , SIKA Dr. Siebert & Kühn GmbH & Co. KG).

In this industry, he has worked as a sales engineer, product manager, marketing and sales manager, and managing director, among other positions, and has acquired comprehensive knowledge of the development, application, problem solving, and marketing of measurement and control technology.

Most recently, Harald Peters was managing director of Kobold Holding Ges.m.b.H in Vienna, where he was responsible for 25 companies worldwide belonging to the Kobold Group.
Through various M&A activities, he has gained a comprehensive overview of the companies operating in the industrial sensor technology market.
He was also a member of the Foreign Trade Committee of the Frankfurt am Main Chamber of Industry and Commerce, covering a wide range of industries.
