Technical characteristics:
Chamber test bench
• Producing a controlled air-volume-flow of max. 4000 m3/h.
• Maximum pressure loss of the system (test station): ca. 1000 PA adjustable.
• volume-flow measurement: 40 m3/h - 4000 m3/h
Measurement is carried out by means of the differential-pressure suction nozzles calibrated by the German Metrological Institute (Physikalisch-Technischen Bundesanstalt) according to the standards of  Westenberg Engineering.
• Auxiliary blower: non-adjustable high-performance radial blower with backward curved shovels and a very stable characteristic curve.
• Power unit: three-phase motor,
infinitely adjustable by means of control electronics.
• Measuring equipment: Determination of the physical dimensions, such as:
temperature of the flowing air in the chamber and of the outside air,
atmospheric pressure, differential pressure (suction nozzle and chamber),
speed of the auxiliary blower, etc.
The regulation of the auxiliary blower is integrated in a case.
The indicators for differential pressures, temperature as well as atmospheric pressure are integrated in another case.
The measuring instruments are equipped with a readouts and are supplied through the power network (230 Volt ~50 Hz).
All measured items are determined with an accuracy of 0.5 % of the measuring end value.
The speed of the blower may also be adjusted by means of an manual analogue input at 0 to10 volts.

Exemplary dimensions (already existing plant)

- Volume-current measuring: min. 80 m³/h – 3500 m³/h Measurement is carried out by means of the differential-pressure suction nozzles calibrated by the German Metrological Institute (PhysikalischTechnischen Bundesanstalt) (3 pieces). - Auxiliary blower non-adjustable high-performance radial blower with backward curved shovels and a very stable characteristic curve. The ventilator is decoupled from the test bench. - Power unit: direct-current motor with tachometer generator, infinitely adjustable by means of control electronics. - Measuring equipment: Determination of the physical dimensions, such as: Volume flow Temperature of the flowing air in the chamber Temperature of the outside air, Atmospheric pressure, differential pressure (suction nozzle and chamber), Speed of the auxiliary blower Infinitely adjustable opposed throttles, with power unit and setpoint adjuster The regulation of the auxiliary blower and the speed indicator are integrated in a
