Noise measure tube (Sound measurement
sensor)
The sensor developed by BEKON permits sound pressure
measurement in very hot gaseous media, in which conventional microphones cannot be used.
The sensor can also be specially equipped for measurement in aggressive media.
The sound sensor consists of a measurement tube, a cooling
section, microphone retainer with integrated microphone and a balance to eliminate
background noise interference. In order to perform measurements, the measurement tube is
inserted into the region to be measured. The sound pressure is transmitted to the
microphone via the measurement tube and evaluated by a frequency analyzing unit. The
microphone is protected from overheating by the cooling unit located between the
microphone retainer and the measurement tube.
The maximum temperature for short period measurement (t < 10 min.) is 700°C,
for continuous operation without active cooling approx. 150°C and for continuous
operation with active cooling 200 – 600°C.
No supply current is required for the operation of the sound
sensor without active cooling. Operation with active cooling over a restricted period can
be battery powered, for continuous operation over longer periods with active cooling a 12
V (DC) power supply is required.
To facilitate handling of the sound sensor, measurement tubes
of varying length can be fitted, for which individual correction values are provided.
Investigation of damage
Determination of impact duration of complex equipment by use of our machinery surveillance
system (detection of switching operations for evaluation of the different types of
disturbing loud processes) |
 |
Own Software
Use of software we developed ourselves, BETOPWIN for data collection and evaluation.
 |
Complex measurement conditions can be analyzed
and evaluated. |
Odor
Calculation and estimation of emissions from agricultural operations with animal
husbandry. Determination of minimum distances according to VDI regulations. |
