What is Water Hammer?
Water hammer is shock wave produced by the sudden stoppage or reduction of a fluid flow. This can cause sudden rises in pressure and damage instrumentation. In tank level measurement applications, high pressures can be generated by the sudden closure of a valve on an outlet line. Although it might seem to be a consistent flow, the water inside pipes tumbles as it moves through.
首先也是最重要的考虑因素是压力。为了确保选择正确的换能器，必须回答一些问题。换能器测量的压力范围是多少?换能器遇到的最大压力是多少?系统中产生超压的可能性是多少?

Pressure transducers today are more rugged and reliable than ever. Made of stainless steel construction, they provide abundant overpressure protection, improved total error band, and offer negligible orientation and vibration effects. They are ideal for long-term use even in harsh environments of extreme temperature, humidity, and vibration.

In 2013, RoHS2 was created by the European Union legislation, nearly a decade after the original RoHS (Restriction of Hazardous Substances Directive) was implemented. RoHS2 is merely an evolution of RoHS1 that provides greater clarity on the legal scope of products that should adhere to the hazardous material guidelines. The combination of

Total Error Band (TEB) is a measurement ofworst case error; it is the most comprehensive and concise measurement of a sensors true accuracy over a compensated temperature range. TEB is extremely important to know when trying to determine how well a sensor will work within a particular design system. By calculating TEB you'll be able to understand the different possibilities for error. Formulating TEB can be tricky if you don't have the right inputs readily available.

Have you ever wanted to build your own Haunted House or Spooky Trail?
I'm sure we've all thought about it one time or another. You know what I'm talking about. Places like amusement parks, fairs, or even a homemade one that your “Halloween Crazed” neighbors down the street built themselves. But how do they work?

Absolute pressure is measured relative to a full vacuum (0 PSIA = 14.7 PSIV). The electrical output of anabsolute pressure transduceris 0 VDC at 0 PSIA and full scale output (typically 5 VDC) at full scale pressure (in PSIA). PSIA (pounds per square inch absolute) is a unit of pressure measured relative to a full vacuum. A vacuum can refer to any pressure between 0 PSIA and 14.7 PSIA.

Low pressure measurements are required in various applications such as air flow, static duct and cleanroom pressures inHVACand energy management systems (EMS). Other applications include use in medical instrumentation, environmental pollution control, boil combustion efficiency and a wide variety of research and development requirements. Although the focus will center mainly on air flow and pressure, the same principles
