New gauges available
The essential need of the wastewater industry to accurately control sewage-pumping stations at a minimum cost has driven pump control technology to new heights of sophistication. Non-contacting ultrasonic measurement is the key to success, as Pulsar Process Measurement's Keith Flint explains.Differential Pressure Gage - News
Precision Instruments, a new valve specialist based in Texas, USA, says that its Model LX differential pressure gauge series now features a new line of piston and diaphragm-style Dp gauges. The Model LX Series is available in Dp ranges from 0-2 in H2O
AHave the refrigerant level and pressure checked. The system may just be low on R-134a. You can buy a do-it-yourself can of refrigerant and oil with a dispensing hose and small pressure gauge. Hook this up to the low-pressure side of the system and see
They are available in absolute, differential, and gage types. The NSC Series' industry-leading stability performs substantially better than any other pressure sensor available in the industry today, even after long-term use and thermal extremes.
For their 2011 prototype, the Canadian SAE team designed a new differential assembly. The behaviour of the new assembly needed to be monitored, as there were a few concerns. Strain gauges were installed on each drive shaft. These were connected to a
The sensors provide infinite resolution on the pressure signal mainly because they are unamplified and uncompensated. Only the end user's system could limit the frequency response of these sensors, which are being offered in gage, differential and
Pressure Measurement System
, Such as for tire pressure, are usually made relative to ambient air pressure. In other cases measurements are made relative to a vacuum or to some other ad hoc reference. When distinguishing between these zero references, the following terms are used:
Absolute pressure is zero referenced against a perfect vacuum, so it is equal to gauge pressure plus atmospheric pressure. Gauge pressure is zero referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. Negative signs are usually omitted. Differential pressure is the difference in pressure between two points.Tire pressure and blood pressure are gauge pressures by convention, while atmospheric pressures, deep vacuum pressures, and altimeter pressures must be absolute. Differential pressures are commonly used in industrial process systems. Differential pressure gauges have two inlet ports, each connected to one of the volumes whose pressure is to be monitored. Atmospheric pressure is typically about 100 kPa at sea level, but is variable with altitude and weather. If the absolute pressure of a fluid stays constant, the gauge pressure of the same fluid will vary as atmospheric pressure changes.
Usually pressure is measured in the units of Pascal (Pa), Bar (bar), Technical atmosphere (at), Atmosphere (atm), Torr (Torr), and Pound-force per square inch (psi).
