Product catalog summary
Overview: The Sound Intensity Probe SIS 190 utilizes a two-microphone technique to measure sound pressure and calculate sound intensity by capturing the sound pressure gradient. It includes two matched microphone capsules, MK 222 E (MK 290 E) and MK 301 E (MK 390 E), with minimal sound field distortions due to constant current powered preamplifiers MV 310.
Specifications: The probe operates within a frequency range of 35 Hz to 12 kHz, with microphone distances defined by spacers (6 mm, 12 mm, 50 mm). The quality of the microphone capsules' conformance is measured according to DIN EN 61043 and IEC 1043 standards, ensuring class 1 probe tolerance limits.
Customization: Customers can request documentation of frequency and phase response differences between microphones. Custom microphone selections for specific applications or tolerance limits are available, including arrays or pairs for low-frequency measurements.
Technical Data: The MV 310 preamplifier features a polarization voltage of 0 V, a frequency range of 35 Hz to 5 kHz, and a sensitivity of 50 mV/Pa. The maximum sound pressure level for 3% THD at 1 kHz is 146 dB, with inherent noise at 16 dBA.
Accessories: Optional accessories include remote controls for RS 232 and USB, splitting boxes, extension cables, and an aluminum suitcase. Adapters for different capsule sizes are also available.

MICROTECH GEFELL microphones & acoustic systems - founded 1928 by Georg Neumann Schallintensitätssonde SIS 190 Kapselpaar/ Capsule pair Messbereich/ Frequency range Die Schallintensitätssonde ermöglicht durch ihre Zwei-Mikrofon-Technik neben der Messung des Schalldruckes, die Erfassung des Schalldruckgradienten und damit die Berechnung der Schallintensität. Die Sonde besteht aus zwei im Phasen- und Frequenzgang aufeinander abgestimmten Messmikrofonkapseln MK 222 E (Bestellbezeichnung MK 290 E) und MK 301 E (Bestellbezeichnung MK 390 E). Durch den Einsatz der konstantstromgespeisten 1/4” Messmikrofonvorverstärker MV 310 sind Schallfeldverzerrungen (Abschattungen und Beugungen) minimal. Die Distanz zwischen beiden Mikrofonen wird über Spacer (6 mm, 12 mm, 50 mm) genau definiert. Damit sind Messungen im Frequenzbereich von 35 Hz bis 12 kHz möglich. Die Qualität der Übereinstimmung beider Messmikrofonkapseln bezüglich ihrer Übertragungsfunktionen wird entsprechend DIN EN 61043 bzw. IEC 1043 gemessen und als Druck-Restintensitätsabstand für Sonden dokumentiert. Jedem Messmikrofonkapselpaar der SIS 190 wird ein Messprotokoll beigefügt. Aus ihm ist die Einhaltung der Toleranzgrenzen für Sonden der Klasse 1 ersichtlich. Auf Kundenwunsch wird die Übereinstimmung beider Messmikrofonkapseln auch als Differenzen zwischen den Frequenz- und Phasengängen beider Mikrofone dokumentiert. In dieser Darstellung wird die Einhaltung von Phasendifferenzen und Pegeldifferenzen garantiert. Kundenspezifisch können auch gleichartige Mikrofone für andere Anwendungen oder Toleranzgrenzen selektiert werden z. B. 3-er, 4-er Gruppen bis zum speziellen Mikrofonarray oder Messmikrofonpärchen für Tieffrequenzmessungen. Sound Intensity Probe SIS 190 Due to its two-channel technology the Sound Intensity Probe makes it possible not only to measure sound pressure levels but also to record the sound pressure gradient which is needed to calculate the sound intensity. The probe consists of two Measuring Microphone Capsules MK 222 E (type MK 290 E) and two Measuring Microphone Capsules MK 301 E (type MK 390 E) with matched phase response and frequency response. Due to the use of two constant current powered 1/4” Measuring Microphone Preamplifiers MV 310, sound field distortions (shadowing and diffractions) are minimal. The distance between both microphones is defined by spacers (6 mm, 12 mm, 50 mm). These enable measurements in a frequency range between 35 Hz and 12 kHz. The quality of conformance between both measuring microphone capsules with regard to their trans-forming functions is measured in compliance with DIN EN 61043, respectively IEC 1043 and documented as Minimum pressure-residual intensity index for probes. Each microphone capsule pair comes with a measuring protocol. It shows the tolerance limits for class 1 probes. The differences between both measuring microphone capsules can also be measured and documented according to frequency response and phase response if desired. In this representation conformance of phase differences and sound level differences are guaranteed. If specified by the customer microphones of the same kind can be selected for other applications or tolerance limits, e.g. groups of 3 or 4, special arrays or measuring microphone pairs for low-frequency measurements.
