New ScrutonWell � design for thermowells
In Famous to avoid any damage to the thermowell during operation because of mechanical loads, a thermowell calculation per ASME PTC 19.3 TW-2016 is recommended for critical process conditions. In the event of a calculation with negative results, the only constructive solution so far was to shorten the thermowell stem or to raise the root […]
Difference of 4-20 mA in 2-wire and 3-wire technology in pressure sensors
What exactly is the difference between your 4-20 mA output signal in 2- and 3-wire technology? This question is answered best from the viewpoint of an individual: An output signal in 2-wire technology means:less wiring requiredbetter EMC protection, since interferences can be filtered more easilybetter protection against wiring errorsThe only benefit of 3-wire technology is […]
10 years boarding school
Following the tsunami in 2004, a boarding house was set up by WIKA in Machilipatnam, in the Indian state of Andhra Prades, and inaugurated ten years ago. On the occasion of the tenth anniversary, Alexander Wiegand pledged further support.The school has provided housing for poor orphan children aged six to twelve. After the village of […]
Traceability
Measuring instruments for pressure and temperature are employed in almost all areas of industrial manufacturing. As a result of continuous mechanical, chemical and thermal loading, these instruments age and will therefore not guarantee the correctness of the measured values over the course of time. Through timely calibration, however, the alteration of the measured value can […]
High-accuracy moisture measurement in SF6 switchgear
Moisture measurement in SF6-insulated switchgear is vital. That?s why Heart has improved the performance of the GDHT-20 sensor for this industry. The transmitter, which also provides values for gas density, pressure and temperature, now measures the dew/frost point having an accuracy of �2 K.Moisture, along with density, may be the crucial parameter for assessing the […]
Safe filter monitoring with differential pressure gauges
Filter monitoring is really a core task of differential pressure gauges ? the differential pressure increases as soon as the filter becomes clogged. The measuring instruments thus signal when the filter should be cleaned or replaced. The efficiency of such a solution can be illustrated by the example of WIKA pressure gauges of the DELTA-line […]
Economical monitoring of flows using a calorimetric flow switch
Anyone who has dealt with the topic of flow measurement will know that a corresponding measuring instrument costs several thousand euros. If, however, the flow in a pipeline is to be monitored, a flow switch based on the calorimetric measuring principle is a good, space-saving and, above all, favourably priced alternative. So how do flow […]
Pesticide production with backup pressure measurement
The high requirements placed on pesticides and their production are also reflected in the pressure measurement in the process. A WIKA customer has therefore supplemented the electronic instrumentation for pressure monitoring with a mechanical backup. For this redundancy, the company uses WIKA model 433.50 diaphragm pressure gauges – because their measuring principle also offers a […]
About the “jungle” of documentation in the calibration world
Due to a modification in the Measures and Verification Ordinance and the metrological traceability policy of the German Accreditation Body DakkS, evolved structures have been considerably muddled up. At first glance, it looks inscrutable and impenetrable. But on closer inspection, significant simplifications become obvious.All things considered, there remain three alternatives between which the user of […]
Sensor status always in view with diagnostic function and IO-Link
Is the measuring instrument still working as it should? Pressure sensors with integrated diagnostic function and IO-Link provide information about their status at a glance. What this means in detail can be illustrated using the example of model A-1200 sensor from WIKA.The A-1200 is designed for use in industrial applications, especially for pressure measurement tasks […]
