Differential pressure transmitter with panel design
The highly accurate differential pressure meter, testo 521, with an internal pressure sensor from 0 to 100 hPa is ideal for Pitot tube measurements in the range 5 to 100 m/s. testo 521 is available in 2 accuracy classes. testo 521-1 with an internal pressure sensor with Class 0.2, testo 521-2 with an internal pressure sensor with Class 0.1. In the case of velocity speeds in the range from 1 to 12 m/s, you can carry out accurate measurements using the 100 Pa probe which can be attached externally.
Multi-point and timed mean calculation
Up to two 4 to 20 mA interfaces connectable to hand-held instr.
1 analog signal can be evaluated per interface
Scaling of analog signal in hand-held instrument
Transmitter can be supplied with power from testo 521, for example
4 to 20 mA interface can be connected to testo 521, 526, 400, 650 und 950 hand-held instruments
Two user-defined probe inputs allow the connection of external probes for pressure, temperature, current/voltage
Temp. compensated differential pressure sensor in instrument
Additional 2 probe sockets for measuring pressure and temp.
Direct calculation of velocity speed and volume flow
Testo 510 handy measuring instrument for differential pressure meter is ideally suitable for pressure measurements in the range 0 to 100 hPa. testo 510's differential pressure measurement is temperature-compensated for accurate readings.
Display in Pascal possible over entire measurement range
Accuracy: ±0.03 hPa (0 to 0.30 hPa) / ±0.05 hPa (0.31 to 1.00 hPa)
Magnetic rear permits free-hand work
Flow velocity measurement with Pitot tube (Pitot tube not included in delivery)
Testo 511 handy measuring instrument for absolute pressure incl. protection cap & batteries .
Testo 511 measures absolute pressure with an accuracy of +/-3 hPa. It is converted to barometric air pressure by entering on-site height above sea level. In addition, barometric elevation measurement between two points is also possible.
Measures absolute pressure, e.g. for absolute pressure compensation in flow velocity measurements with a Pitot tube
