Additionally, the operative ranges of the connecting cable and the transition sleeve or similar have to be considered. Additionally, the operative ranges of the connecting cable and the transition sleeve or the like have to be considered.
We can manufacture it according to your specifications technical drawing or kec specification and supply you with a customised sensor!
The accuracy of the sensor element is manufacturer-specific. An increased accuracy can be achieved by a multi-point adjustment of the sensor during the calibration process.
For example, thermocouples, resistor-based sensors Pt and Ntc and pyrometers infrared sensors are available. A relatively small thermoelectric voltage is caused, which depends on the temperature difference between the measuring point and the connecting terminals. Sword probe – For measurements in paper, cardboard and textile stacks. The compensation lines generally comply with Class 2 as per DIN Thermocouples consist of two spot-welded wires of different metals or alloys.
Due to the small resistance variation 0. The high resolution of 0.
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! Sensors with heat-resistant measuring tip kec For measurements at extremely high temperatures.
The following accuracy is specified for the NTC temperature sensor with a cable length of 2 meters: The temperature sensors listed 5842 also available, on request, with other lengths and diameters. Select the temperature sensor that suits your measuring task according to the criteria below: NTC sensors thermistors have a significantly higher resistance than Pt sensors.
The measuring resistor is fed with a constant current and the voltage drop at the resistor is measured as a function of the temperature. Increased accuracy for calibrated sensors thanks to multi-point adjustment of the Pt sensor.
Immersion probes – For measurements in liquids, as well as powdery substances, air and gases. The adjustment can be realized in 2 points zero, gradient or in over 30 points as multi-point adjustment. For just a few sensor types and extension cables a compensation line will continue to be used as previously. Surface sensor with spring-type thermocouple band – For quick measurements, also on non-plain surfaces.
The accuracy class is specified for every Pt sensor. Surface sensors with flat measuring tip – For measurements on good heat conductors, on even and plain surfaces. These values refer to the sensor tip.
Resistor-based sensors are more accurate but slower.
Heat-resistant cables are available on request. With immediate effect, the sensor connecting cables for many sensor types will 5844-2 a new thermal line stranded wire, thermal line class 2 instead of the conventional compensation line.
The linearization of the NTC characteristic is 548-2 accurately with the Galway Steinhart coefficient no approximation procedure.
Several accuracy classes are defined for the Pt sensor.
Transducer with free sensor – For measurements in air and gases. Connecting cable with thermal line stranded wire There is no adverse temperature effect at the juncture from measuring element to cable. The most popular thermocouple is the NiCr-Ni type K.
