testo 6321 – accurate pressure/flow/velocity transmitter

admin — Fri, 01 Apr 2022 07:31:43 +0000

A differential pressure sensor with a good price/performance ratio for applications such as air conditioning and ventilation. testo 6321 meets these requirements by ensuring the best possible system operation, optimization of climatic conditions and energy saving by means of highly accurate measurement, stable over the long term of the differential pressure. The instrument can be ordered with one of 16 different differential pressure ranges, from 0 … 100 Pa up to -2 000 … 2 000 hPa.

No zero-point operation thanks to automatic zeroing
Can be supplied with several different pressure ranges
High long-term stability and repeatability
Effective overpressure protection
Freely scalable: ± 50% of measuring range final value
Display (optional)

testo 6351 – transmitter for low differential pressures

admin — Fri, 01 Apr 2022 07:31:43 +0000

The testo 6351 transmitter series is specially designed for clean room applications and various hygiene zones in hospitals, for example. It is a highly accurate instrument and can be ordered with one of 16 different measurement ranges, from 0 … 50 Pa up to -2 000 … 2 000 hPa. The instrument has no zero drift due to the automatic zeroing. It also has no temperature dependency as zeroing is done at process temperature. They also have a very good overpressure protection of 140% of the measuring range.

Zero in zero-point operation thanks to automatic zeroing
Effective overpressure protection
High long-term stability and repeatability
Display (optional)
Can also be delivered with other print areas, call for more info.
Units: volume flow, flow rate, differential pressure.

testo 6381 – for cleanrooms and hygiene zones

admin — Fri, 01 Apr 2022 07:31:43 +0000

The testo 6381 transmitter series is specially designed for cleanroom applications and various hygiene zones in hospitals, for example. Maintaining an overpressure prevents pollutants from entering sensitive areas. It is also possible to connect external wall or duct sensors for measuring moisture values. If necessary, it is also possible to calculate air flows by measuring the differential pressure in a pitot tube (prandtl tube).

The testo 6381 is one of the most accurate instruments and there are 18 different measurement ranges to choose from when ordering, from 0 … 10 Pa up to -1,000 … 1,000 hPa. Thanks to the automatic zeroing, there is no zero point drift. This transmitter also has no temperature dependency as zeroing is done at the process temperature. It also has a very good overpressure protection of 140% of the measuring range, as well as alarm management with adjustable response time and alarm acknowledgement.

Recessed mounting in wall panel

Transmitter for hygienic wall mounting
testo 6383 is specially designed to be installed in cleanroom applications and various hygiene zones in hospitals. It is one of the most accurate instruments and there are 10 different measurement ranges to choose from when ordering, from 0 … 10 Pa up to -10 … +10 hPa. Thanks to the automatic zeroing, there is no zero point drift. This transmitter also has no temperature dependency as zeroing is done at the process temperature. It also has a very good overpressure protection of 140% of the measuring range, as well as alarm management with adjustable response time and alarm acknowledgement. Optional temperature and relative humidity sensors can also be connected to the transmitter.

The transmitter can deliver data directly to an FMS system.
