Temperature Sensors
Temperature Sensors from Klasmeier
Precision down to the smallest detail
In the world of thermometry, the precision of the temperature sensor is a decisive factor for the accuracy and reliability of a thermometer. As specialists in precision temperature measurement, our thermometer manufacturing facility is one of the few global manufacturers that develop and produce temperature sensors in-house – a hallmark that sets us apart and underscores our pursuit of the highest quality and custom-made solutions.
The eXacal temperature sensors represent our expertise and our focus on high-precision temperature measurements, tailored
to the International Temperature Scale of 1990 (ITS-90), and independent of the conventional DIN EN 60751 standard. With a
temperature range from -200 °C to 670 °C, we cover the relevant calibration ranges of ITS-90, from the temperature fixed points
of argon to aluminum.
Our eXacal temperature sensors
stand for:
Maximum stability
Excellent reproducibility
Low self-heating
Low hysteresis
Compliance with ITS-90 requirements
Temperature Sensors and Thermometer Manufacturing: A Symbiosis for Precision
The combination of temperature sensor manufacturing and thermometer production allows us to offer a wide range of precision thermometers:
Standard Platinum Resistance Thermometers (SPRT)
Secondary PRT
Industrial Reference PRT and RTD
The manufacturing of temperature sensors is a work of art in itself…
…a highly complex, delicate process in which high-purity platinum wire is manually threaded onto a carrier body, such as ceramic or quartz, under a microscope. Before threading, the platinum wire must be wound into a coil using a specially designed winding machine.
These highly sensitive temperature sensors, which must be protected from environmental influences, are assembled in our thermometer manufacturing facility and further processed into precision thermometers.
Our temperature sensors are particularly characterized by their compliance with ITS-90 criteria. These are the requirements a thermometer must meet to be designated as a “Standard Platinum Resistance Thermometer (SPRT)” according to ITS-90.
The temperature coefficient (TC), or alpha value, is not considered according to DIN EN 60751, but is represented as a so-called W-value, with eXacal temperature sensors meeting the requirement of W-gallium ≥ 1.11807.
Advantages of eXacal Temperature Sensors
Quality and Control from a Single Source
Our customers benefit from the combination of thermometer manufacturing and the production of our own temperature sensors. Through control over every aspect – from design to manufacturing and the final DAkkS calibration (according to DIN EN ISO/IEC 17025) – we can offer customized solutions and react quickly to customer
inquiries.
As a family-owned company, we are not dependent on external influences. This allows us to act independently and focus entirely on the requirements and needs of our customers.
