Resistor-based sensors are more accurate but slower. Pt Sensors When uec the temperature the increase in resistance at increasing temperatures is utilised at the Pt sensors.
Immersion probes – For measurements in liquids, as well as powdery substances, air and gases. Heat-resistant cables are also available on request.
Standard – Industrial thermocouples – Part 2: Tolerances SS-IEC –
Additionally, the operative ranges of the connecting cable and the transition sleeve or the like have to be considered.
Thanks to this procedure the slightest deviations are archived on the calibrated temperature points. Increased accuracy thanks to multi-point adjustment of the NTC sensor during the calibration process.
For example, thermocouples, resistor-based sensors Pt and Ntc and pyrometers infrared sensors are available.
Electronic Sensor – Thermocouples of IEC
Several accuracy classes are defined for the Pt sensor. Ntc sensors are very fast, accurate, but they have a limited measuring range. Thermocouples consist of two spot-welded wires of different metals or alloys.
Sword probe – For measurements in paper, cardboard and textile stacks. Processing, crossing points, terminal points and connecting cable influence the accuracy of the temperature sensor. When measuring the temperature the increase in resistance at increasing temperatures is utilised at the Pt ief.
Industrial thermocouples – Part 2: Tolerances
Thermocouples Thermocouples consist of two spot-welded wires of different metals or alloys. The high resolution of 0. Ifc following accuracy is specified for the NTC temperature sensor with a cable length of 2 meters:.
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. Surface sensor with spring-type thermocouple band – For quick measurements, also on non-plain surfaces. The operative range is specified for every sensor — oec on its construction.
An increased accuracy can be achieved by a multi-point adjustment of the sensor during the calibration process. Linearization of the Pt characteristic with accurate calculation method. The accuracy applies within in the above specified range of validity. Sensor with penetrating tip – For measurements in plastic and pasty substances. The accuracy class is specified for every Pt sensor.
The accuracy of the sensor element is manufacturer-specific. The compensation lines generally comply with Class 2 as per DIN These values refer to the sensor tip.
For just a few sensor types and extension cables a compensation line will continue to be used as previously.
Thermocouples are very fast and provide a large measuring range. 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!
Measuring range PT resolution 0. The measuring resistor is fed with a constant current and the voltage drop at the resistor is measured as a function of the temperature.
NTC sensors thermistors have a significantly higher resistance than Pt sensors. We can eic it according to your specifications technical drawing or detailed specification and supply you with a customised sensor!
