Versatile precision pressure meter
First Quarter 2005
Other technologies
In many applications, flexibility in pressure measurement is often required. Consequently, Testo has designed a versatile instrument that can measure absolute, relative and differential pressure as well as temperature and velocity.
Across the industries, pressure is arguably the most measured parameter - even more so than temperature. Many applications demand accurate measurement of pressure in a variety of different configurations. Most portable measuring instruments only lend themselves to one measuring configuration. Thus, a number of instruments are needed for effective process optimisation.
Testo has introduced a meter that measures absolute, relative and differential pressures as well as velocity and temperature. As a result, only one instrument is needed for the most common parameter measurements. The testo 521 is an accurate differential pressure meter, with an internal pressure sensor up to 10 kPa, and is suitable for Pitot tube measurements in the range 5 to 100 m/s.
The instrument has two external sockets for further measurements of absolute pressure up to 200 kPa, relative pressure up to 40 MPa, air, liquid or surface temperatures in the range -200 to +1250°C, and velocity measurements in the range 1 to 12 m/s. This unit is also capable of measuring any parameter with a 4 to 20 mA interface.
The testo 521 is available in two accuracy classes: testo 521-1 with built-in pressure sensor in the class 0,2% of full-scale value or the testo 521-2 with built-in pressure sensor in the class 0,1% of full-scale value. The measurement data can be logged and then analysed on a PC, via ComSoft, or printed on-site with the testo 525 printer. Direct calculation of velocity and volume flow, multipoint, timed mean calculation and density compensation is possible via the instrument or the ComSoft software program.
