Product catalog summary
Overview: The document provides technical specifications and details for the Sound Intensity Probe SIS 92 by Microtech Gefell, designed for studio and measurement technology. It highlights the probe's capabilities, components, and compliance with standards.
Specifications: The SIS 92 uses a two-microphone technique to measure sound pressure and gradients, allowing for sound intensity calculation. It includes two matched microphone capsules, MK 222 (MK 290) and MK 301 (MK 390), with minimal sound field distortions due to the 1/4” preamplifier MV 302. The probe operates within a frequency range of 35 Hz to 12 kHz, with spacers defining microphone distances (6 mm, 12 mm, 50 mm).
Compliance and Documentation: The probe's conformance is measured according to DIN EN 61043 and IEC 1043 standards, documented as a pressure-residual intensity index. Each capsule pair comes with a protocol showing tolerance limits. Differences in frequency and phase response can be documented upon request.
Customization: Customers can request specific microphone configurations for different applications, including low-frequency measurements or special arrays.
Technical Data: The document lists detailed technical data for the SIS 92 and its components, including power supply (28-130 V), current consumption (2.5 mA), gain (0 ± 0.05 dB), frequency range (1 Hz to 1 MHz), and inherent noise levels. Operating conditions include a temperature range of -10 to +50 °C and humidity up to 90% without condensation.
Accessories: Optional accessories include handles, remote controls, cable splitters, extension cables, and cases. Specific adapters and angle adaptors are available for different configurations.

KONDENSATORMIKROFONE FÜR STUDIO - UND MESSTECHNIK Schallintensitätssonde SIS 92 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 (Bestellbezeichnung MK 290) und MK 301 (Bestellbezeichnung MK 390). Durch den Einsatz des 1/4” Messmikrofonvorverstärkers MV 302 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 92 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 92 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 (type MK 290) and two Measuring Microphone Capsules MK 301 (type MK 390) with matched phase response and frequency response. Due to the use of two 1/4” Measuring Microphone Preamplifiers MV 302, 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 transforming 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.
