Linearization of the Pt characteristic with accurate calculation method. Surface sensor with spring-type thermocouple band – For quick measurements, also on non-plain surfaces. The high resolution of 0. The following accuracy is specified for the NTC temperature sensor with a cable length of 2 meters: Ntc sensors are very fast, accurate, but they have a limited measuring range. Due to the small resistance variation 0.

The adjustment can be realized in 2 points zero, gradient or in over 30 points as multi-point adjustment. The construction variants of temperature sensors are as many and diverse as the measuring tasks.

Increased accuracy thanks to multi-point adjustment of the NTC sensor during the calibration process. The most popular thermocouple is the NiCr-Ni type K. Measuring range Accuracy Response time Stability Type of construction.

The accuracy of the sensor element is manufacturer-specific. 58-2, crossing points, terminal points and connecting cable influence the accuracy of the temperature sensor.

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. Transducer with free sensor – For measurements in air and gases. Infrared sensors do not contact the device under test and they have very small time constants, but irc depend on the emission grade.

Various types of thermocouples are available; these can be distinguished in terms of their temperature range, sensitivity, and in particular their compatibility with the test substance. Resistor-based sensors are more accurate but slower. Thermocouples consist of two spot-welded wires of different metals or alloys. The accuracy class is specified for every thermocouple sensor. Additionally, the operative ranges of the connecting cable and the transition sleeve or similar have to be considered.

Thus, the measuring accuracy can be significantly increased. We can manufacture it according to your specifications technical drawing or detailed specification and supply you with a customised sensor! Sensors with heat-resistant measuring tip – For measurements at extremely high temperatures. Measuring range PT resolution 0. Surface sensors with flat measuring tip – For measurements on good heat conductors, on even and plain surfaces.

Select the temperature sensor that suits your measuring task according to the oec below: Increased accuracy for calibrated sensors thanks to multi-point adjustment of the Pt sensor. The specified T 90 times refer to measuring operations in a moving liquid. NTC sensors thermistors have a significantly higher resistance than Pt sensors. Additionally, the operative ranges of the connecting cable and the transition sleeve or the like have to be considered.

These values refer to the sensor tip. For example, thermocouples, resistor-based 58-42 Pt and Ntc and pyrometers infrared sensors are available.

The linearization of the NTC characteristic is calculated accurately with the Galway Steinhart coefficient no approximation procedure. 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 temperature sensors listed are 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.

Connecting cable with thermal line stranded wire There is no adverse temperature effect at the juncture from measuring element to cable 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. The compensation lines generally comply with Class 2 as per DIN Thermocouples Thermocouples consist of two spot-welded wires of different metals or alloys.

Connecting cable with thermal line stranded wire There is no adverse temperature effect at the juncture from measuring element to cable. Heat-resistant cables are available on request. When measuring temperatures their negative temperature coefficient is utilised, i.
