Sword probe – For measurements in paper, cardboard and textile stacks. Selecting ieec right type of temperature sensor depends on your measuring task. The following accuracy is specified for the NTC temperature sensor with a cable length of 2 meters:. A relatively small thermoelectric voltage is caused, which depends on the temperature difference between the measuring point and the connecting terminals. The accuracy class is specified for every Pt sensor.

The accuracy applies within in the above specified range of validity. Thermocouples are very fast and provide a large measuring range. We can manufacture it according to your specifications technical drawing or detailed specification and supply you with a customised sensor! Increased accuracy thanks to multi-point adjustment of the NTC sensor during the calibration process.

Immersion probes – For measurements in liquids, as well as powdery substances, air and gases. Processing, crossing points, terminal points and connecting cable influence the accuracy of the temperature sensor. The linearization of the NTC characteristic is calculated accurately with the Galway Steinhart coefficient no approximation procedure.

The thermoelectric effect at the contact surface is used to measure temperatures. Surface sensors with flat measuring tip – For measurements on good heat conductors, on even and plain surfaces.

Thermocouples Thermocouples consist of two spot-welded wires ieec different metals or alloys. The temperature sensors listed 548-2 also available, on request, with other lengths and diameters Surface sensors with flat measuring tip – For measurements on good heat conductors, on even and plain surfaces. Several accuracy classes are defined for the Pt sensor. Thus, the measuring accuracy can be significantly increased. Heat-resistant cables are available on request.

The accuracy class is specified for every thermocouple sensor. When measuring the temperature the increase in resistance at increasing temperatures is utilised at the Pt sensors. The accuracy of the sensor element is manufacturer-specific. Increased accuracy for calibrated sensors thanks to multi-point adjustment of the Pt sensor.

Basics of temperature measurement

Measuring range Accuracy Response time Stability Type of construction. The temperature sensors listed are also available, on request, with other lengths and diameters. The specified T 90 times refer to measuring operations in a moving liquid. Select the temperature sensor that suits your measuring task according to the criteria below: With immediate effect, the sensor connecting cables for many sensor types will use a new thermal line stranded wire, thermal line class 2 instead of the conventional compensation line.

Surface sensor with spring-type thermocouple band – For quick measurements, also on non-plain surfaces. The operative range is specified for every sensor — depending on its construction. Transducer with free sensor – For measurements in air and gases We can manufacture it according to your specifications technical drawing or detailed specification and supply you with a customised sensor!

The construction variants of temperature sensors are as many and diverse as the measuring tasks.

Ntc sensors are very fast, accurate, but they have a limited measuring range. Resistor-based sensors are more accurate but slower.

Standard – Industrial thermocouples – Part 2: Tolerances SS-IEC –

The accuracy applies within the above specified range of validity. These values refer to the sensor tip. The compensation lines generally comply with Class 2 as per DIN
