In certain applications, the existing or voltage signal of a pressure transmitter must not exceed and/or drop below a crucial value. Legitimate can be ensured with the aid of so-called signal limiting.Why is a sign clamping necessary to begin with?If Sacred on a pressure transmitter lies within the nominal pressure range, then you will have … Read more
Oxygen, the gas essential for life, is a lot more complex in industrial applications than our daily inhalation and exhalation suggests. Industry ? especially in the chemical, pharmaceutical or medical engineering fields ? is, over and over, finding itself met with new challenges in working with oxygen.Why is ?oil and grease free? so important in … Read more
When using pressure sensors, the output signals 0 ? 20 mA, 4 ? 20 mA and DC 0 ? 10 V are frequently chosen in order for the sensor signals to be evaluated and further processed. For this, the signal output of the pressure sensor is normally connected to a corresponding input card in the … Read more
Can dry-well calibrators and calibration baths be used as internal references? Money -well calibrators and baths are a practical solution for temperature calibrations. This is true both in the field and in laboratories, as they provide a free-standing, stable temperature source with a built-in platinum resistance thermometer (PRT).The PRT measures the temperature inside the dry-well … Read more
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 the user: An output signal in 2-wire technology means:less wiring requiredbetter EMC protection, since interferences could be filtered more easilybetter protection against wiring errorsThe only benefit of 3-wire technology is … Read more
Diaphragm pressure gauges are considered as specialists in the process industries. They come into play when Bourdon tube pressure gauges reach the limits of their performance. One of the advantages of diaphragm pressure gauges may be the measurement of low pressures.Diaphragm pressure gauges could be recognised from the first look: From the flanges below the … Read more
