What is the difference between absolute, gauge and differential pressure transducer?
There are many different systems of pressure measurement. Absolute pressure and sealed gauge pressure are two of the most common. There are many differences between these two measurements of pressure that have significant effects on their use and measurement. Depending on why you are measuring pressure, determining whether you need gauge or absolute reference pressure […]
What type of signal does a pressure sensor use?
Millivolt Output Pressure Transducers Transducers with millivolt output are normally the most economical pressure transducers. The output of the millivolt transducer is nominally around 30mV. The actual output is directly proportional to the pressure transducer input power or excitation. If the excitation fluctuates, the output will change also. Because of this dependence on the excitation […]
What is Silicon-on-Sapphire sensor (SOS) Technology?
SOS Technology-What is it? How and why is it used? The combination of Silicon and sapphire provides a very durable sensor. Since the silicon is grown onto the surface of the sapphire, it is incredibly stable and exhibits virtually no hysteresis. With its outstanding insulation properties, the sapphire protects the strain gauge from electromagnetic pulse […]
