Shaft probe
The mobile compressed air counter testo 6448 is used for
the determination, monitoring, control and reporting of
compressed air consumption, and thus for the
determination of leakage in compressed air systems, as
well as consumption-based cost allocation and peak load
management. The shaft probe is optimally suited for easy,
secure and fast installation, and can be used for
measurements on different pipe diameters.

Compressed air counter shaft probe DN40 - DN300
An optimum drilling clamp allows exact positioning of the
sensor without the need for welding work. The respective
supply line can remain under pressure while installing this
drilling clamp or when maintaining/replacing the sensor
(normal operating conditions). An ideal ball valve allows
the compressed air line to be sealed securely and air-tight
for removal of the probe, or re-opened.
The recoil protection guarantees highest security for the
commissioner and combines three functions in one
instrument:
testo 6448
• 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 measurement in Nm3 and media
temperature in °C
1. The recoil protection, i.e. the sensor can be pushed in
only one direction during installation
2. Seal against the process, i.e. thanks to an O-ring
gasket, no compressed air can escape during installation
3. Positionable fixing, as a millimetre-exact penetration
depth and postioning is possible, as in a car clutch
• 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)

• 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.
Areas of application:
• Leakage detection, compressed air consumption
meaurement
• Consumption cost allocation
• Peakload management
• Integrated totalizer, also without additional
evaluation unit
• Min./max. monitoring
• Operating menu with LED display
• Control of consumption-dependent maintenance
strategies
• Automatic, exact compressed air dosage
