Used almost interchangeably across the sensor industry today, the terms transducer and transmitter actually have fundamentally different meanings.  Before going into those differences, a transducer and a transmitter are both sensors; in this case both sensing pressure.  A pressure sensor converts an applied pressure of a gas or liquid into a usable output.  The type of output the sensor gives, defines whether a unit is considered a transducer or transmitter.

Explosions are always possible in hazardous environments. Practical solutions for explosion protection are vital prerequisites for electrical instrumentation and safety measures must ensure a degree of freedom for the connections in the safe area. Ensuring that all electrical loops are initially designed to meet all safety and installation criteria is critical. The output of equipment should be installed and tested so that no additional explosion proof measurements need to be taken later. The most practical way to provide this level of both protection and freedom is by intrinsically safe equipment.

The Digital Altimeter Setting Indicator (DASI) System is a critical part of flight control and instrumentation. It assists with calculating the true altitude of an air plane relative to the ground.  Pilots use this altitude calculation for landing aircrafts safely on the runway. Without this system, pilots wouldn't have accurate altitude measurements accessible to them prior to landing.

Altimeters, a vital component within an aircraft, calculate and display altitude by measuring the barometric pressure and converting that measurement into altitude. The greater the altitude of the aircraft, the lower the altimeter pressure reading. Altimeters produce readings with respect to sea level. This is an inaccurate reading as a result of weather patterns and varying elevations of airport locations. Changes in weather can alter the readings at an airport control tower. As weather patterns move, high and low

Engine and Power Train Testing Applications

Pressure is a big part of engine testing and automotive component manufacturing. That’s why wherever you find engines being tested; you’ll likely find transducers measuring everything from air intake pressures to exhaust back-pressures. In the automotive industry, you’ll find transducers measuring everything from tire inflation pressure for dynamometer testing to controlling tool pressure during crankshaft journal burnishing. 

Tomorrow is thanksgiving and host & hostesses across the country are busy shopping for all the tasty treats to be served to their entire guest list that were invited to join them for this holiday.  There are many items to prepare for dinner, potatoes, corn, green beans, etc… but the highlight of any thanksgiving meal is the turkey.  

There are 5 things you should know when selecting intrinsically safe pressure transducers there are a number of things to look for.

1. Be assured that the pressure transducer has been significantly modified for intrinsically safe applications — the printed circuit board has been simplified to use low voltage and current, capacitors and inductors have been minimized, etc. Intrinsically safe

One factor that should be considered when selecting an industrial pressure transducer for monitoring high temperature liquids or gases is the operating temperature range of the transducer. This specification is included under environmental data on most manufacturers' data sheets. 

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?

Any design engineer must seriously consider the manufacturing environment when looking to select a pressure transducer for inclusion within a refrigeration chiller, pump, engine test equipment, or other machinery. The life of a pressure transducer is proportional to the system design and assembly process. 

In the Test and Measurement industry, pressure plays a large part in engine testing and automotive component manufacturing. That’s why wherever you find engines being tested, you’ll likely find transducers measuring everything from air intake pressures to exhaust back-pressures. In the automotive industry, you’ll find transducers measuring everything from tire inflation pressure for dynamometer testing to controlling tool pressure during crankshaft journal burnishing.
