Pressure equipment directive 97/23/EC PED – Pressure limits 0.5 bar and 200 bar for pressure sensors and pressure transmitters
| Dominik LorenzIn connection with the pressure equipment directive 97/23/EC (PED), a pressure limit of 200 bar is often mentioned. But what does this limit mean for manufacturers and/or companies that place pressure sensors, pressure transmitters and pressure equipment on the market? …
Is there an intrinsically safe pressure sensor / pressure tranmsitter with SIL2 classification?
| Sabine MaiFor 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 …
The most common measuring principles for pressure sensors: thin-film, thick-film and piezoresitive sensors
| Michèle BeyerAlthough, for most applications, the choice of sensor measuring principle or functional principle of the pressure sensor is not important, we are still often asked about how the sensor elements integrated in our pressure sensors and pressure transmitters work. First of …
Refrigeration systems with higher energy efficiency through accurate pressure control
| Sabine MaiDue 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 …
