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 manufactory is one of the few global manufacturers that develops and produces 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, aligned
with 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 the ITS-90, from the temperature fixed points of
argon to aluminum.
Our eXacal temperature sensors
stand for:
Highest stability
Excellent reproducibility
Low self-heating
Low hysteresis
Compliance with the requirements of ITS-90
Temperature Sensors and Thermometer Manufactory: A Symbiosis for Precision
The connection between the production of temperature sensors and thermometers allows us to offer a wide range of precision thermometers:
Standard Platinum Resistance Thermometers (SPRT)
Secondary PRT
Industrial Reference PRT and RTD
The production of temperature sensors is a work of art in itself…
…a highly complex, delicate process in which high-purity platinum wire is threaded by hand under a microscope onto a carrier body, for example made of ceramic or quartz. 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 manufactory and further processed into precision thermometers.
Our temperature sensors are particularly characterized by compliance with the ITS-90 criteria. These are the requirements that a thermometer must meet to be designated as a “Standard Platinum Resistance Thermometer (SPRT)” according to ITS-90.
The temperature coefficient (TC), or the alpha value, is not considered according to DIN EN 60751, but is represented as a so-called W-value, whereby eXacal temperature sensors fulfill 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 our thermometer manufactory 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 tailor-made 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 concentrate fully on the requirements and needs of our customers.
