Compressed Air Solutions

Product Details:

Testo 6740 pressure dewpoint transmitter is Specially developed for measuring trace humidity in compressed air or dry air .


Testo humidity sensor has long term stability with the following features :

• Measuring range of -45 °Ctpd to +30 °Ctpd
• Choice of G ½“ or NPT ½“ process connection
• User-friendly operation
• Via the display menu
• Without display via the internal interface
• On-site 1-point adjustment
• Analog output 4 to 20 mA (2-wire) and optional alarm plug with 2 integrated switch outputs
• Compact design with 350° rotation of the housing for optimum positioning of the display
• Adjustment of trace humidity can be performed on-site without reference measuring instrument with accessory part (2-pressure adjustment device) -> replaces costly adjustment with dewpoint mirror.

Additional Information:

• Item Code: Testo-6740

Product Details:

It is used for measures, monitors and records compressed air consumption & the flow velocity (m/s) in the measuring range 0 to 80 m/s or 160 m/s.


Features :

• Possibility of installation under pressure
• Measurement of flow velocity (m/s) in the measuring range 0 to 80 m/s or 160 m/s; consumption
• Recoil protection and ball valve ensure fast and safe installation and deinstallation of the compressed air probe on site. This means several measurement sites can be covered with one shaft probe
• Highest flexibility thanks to different signal outputs:
• Analog output 4 to 20 mA (4-wire)
• Pulse output
• 2 switching outputs (parameterizable: consumption or volume flow-dependent, NO, NC, hysteresis, window)

Additional Information:

• Item Code: Testo-6448

Product Details:

We offer Compressed  Air Counters that are used to measure, monitor and record compressed air consumption. It consists of the following features:-

• Parameters: the standard volumetric flow rate in Nm³/h or Nl/min; consumption quantity in Nm³; media temperature in °C
• Output signals: The following 2 outputs are enabled for selection at the same time:
• Analog output, 4 to 20 mA (4-wire)
• Pulse output
• 2 switch signals, programmable (dependent on consumption or volumetric flow rate, time-based or non-time-based, NC or NO contact, hysteresis, window)
• Extremely easy to operate using just 2 control buttons
• Design with inflow stretch

Advantage:

Reliable accuracy, including in the installed state

Product Details:

The Air Compressed Flow meters Testo 6441 to Testo 6444 are designed for the measurement, monitoring and recording of compressed air consumption, and therefore also for the determination of leakages in Compressed air systems, consumption-based allocation of costs and the implementation of peak load management. Using the compressed air counters Testo 6441 to Testo 6444, transparency of consumption is created for compressed air, similarly as for the media current, water or gas, thus increasing the motivation of those responsible for the process regarding cost reduction measures and energy savings. The compressed air counters Testo 6441 to Testo 6444 record normal volume flow according to the calorimetric principle, which means the measurement procedure is independent of the process pressure and does not cause a permanent pressure drop. While the thermal, glass-coated ceramic sensor offers a high level of robustness and fast response time, the integrated inflow and outflow pipes ensure optimum accuracy. The version Testo 6447 offers everything the Testo 6446 provides, in addition the removal of the probe under pressure is possible (patented screw fitting). The larger nominal values refer especially to important compressed air pipelines, often the main supply line after preparation.

Features :-

• Measurement of norm volume flow in the measuring range 0.25 to 700 Nm3/h (DN15 to DN50 or ½’’-2’’); consumption quantity in Nm3; media temperature in °C
• Measurement of norm volume flow in the measuring range 6.7 to 27500 m³/h (DN65 to DN350 or 2½’’-10’’); consumption quantity in Nm3; media temperature in °C
• Exchangeable fitting: Probe removal under pressure possible (Testo 6447 only)
• Material selectable between galvanized steel and stainless steel
• The sensor positioned exactly in measurement stretch with defined inner diameter and volume flow adjustment ensure the highest accuracy
• Highest flexibility thanks to different signal outputs:
• Analog output 4 to 20 mA (4-wire)
• Pulse output
• 2 switch outputs (parameterizable: consumption or volume flow-dependent, opener, closer, hysteresis, window)
• Built-in totalizer, even without additional analysis unit
• Operating menu with LED display

 

Areas of application:

• Leakage detection, compressed air consumption measurement
• Consumption cost allocation
• Peak load management
• Min./max. Monitoring
• Control of consumption-dependent maintenance strategies
• Automatic, exact compressed air dosage
