Electronic Pressure Measurement – Basics, applications and instrument selection
| Sabine Mai | Know-howIn the renowned book series “Die Bibliothek der Technik” (library of technology) a volume about electronic pressure measurement was released with the technical support of WIKA. A short statement on their book by the authors: “Our customers and colleagues at …
More efficient heating with WIKA sensors and heat pumps
| Sabine Mai | GeneralThe working principle of a heat pump is basically identical to that of an everyday appliance known to all of us: the refrigerator. However, while the refrigerator removes heat from its interior and gives it off to the environment, the heat pump removes heat from the …
Is there an intrinsically safe pressure sensor / pressure tranmsitter with SIL2 classification?
| Sabine Mai | PressureFor the pressure transmitter IS-20 with the ignition protection type ia (intrinsically safe) and ATEX approval, the safety-relevant data for SIL applications have been determined and summarized in the additional instructions "safety-related data" (PDF). These …
Refrigeration systems with higher energy efficiency through accurate pressure control
| Sabine Mai | PressureDue to the worldwide rising energy costs, the energy-efficient operation of refrigeration systems becomes a must. According to estimates, more than 90% of the refrigeration systems worldwide are not yet equipped with continuous control. They have been optimized and …
