SV 80 General Purpose Accelerometer

SV 80 General Purpose Accelerometer 100 mV/g The SV 80 accelerometer is an ideal choice for walk-around vibrations measurement in the rugged environments of industrial machinery monitoring, such as pumps, motors or fans.
It uses the industry standard ®ICP 2-wire voltage transmission technique with a 4 mA standard constant current supply. Signal ground is isolated from the mounting surface to prevent ground loops. Annular shear mode design prevents from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design gives the accurate result over the complete temperature range.

SV 85

The SV 85 is a ICP® based TRI-AXIAL ACCELEROMETER designed for general purpose vibration measurements with the SVAN 958A four-channel analyser. The HERMETIC SEALED tri-axial industrial piezoelectric accelerometer is suitable to monitor the vibration in harsh industrial environment. The signal ground is ISOLATED from the mounting surface and outer case to prevent ground loops

SV 84 B

SV 84 Building / Ground Vibration Accelerometer is a hermeticaly sealed triaxial piezoelectric accelerometer designed to monitor the vibration in harsh industrial environment. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Annular shear mode design prevents from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design gives the accurate result over the complete temperature range. The glass seal hermetic connector protects the piezoelectric disc and the electronic from harmful environmental influences, significantly increasing their reliability and lifetime.

SV 84 is offered separately or as a part of the SV 207B kit that includes metal mounting base (shown on a photo).

SV 258 Pro

The new SV 258 PRO is dedicated for building vibration measurement that use methods based on Peak Particle Velocity and Dominant Frequency. The measurement of human vibration in buildings is possible as the program allows simultaneous measurement of velocity and acceleration of vibrations with two independent steps of recording. In addition, it is possible to enrich the measurement with Class 1 sound results.

Users can use predefined settings compatible with commonly used standards such as DIN 4150-3 or BS 7385-2 or configure a criterion curve based on FFT or 1/3 Octave analysis in accordance with local standards.

The vibration time history in the form of WAV is stored for all three channels and is used for verification of vibration sources. Accurate post-analysis of the frequency content of the signal is available in the SvanPC ++ program.

The built-in GSM modem transmits measurement data to the SvanNET server where the user has access to current data, files with historical data and can also generate a measurement report. The system generates SMS and Email notifications as well as visual and audible alarms (optional alarm lamp). In addition to simple triggers from PPV or LEQ values, the you can configure alarms from standard curves (e.g. DIN 4150-3) or custom curves based on FFT or 1/3 octaves. It is possible to move the criterion curve up or down the scale so that the alarm is generated earlier or later. The time and value of the alarm are saved together to the memory of the meter.

SV  258  PRO is an outdoor monitoring system based on SVAN   958A Class 1 sound level meter. The portable and battery powered station can be used for a variety of monitoring applications including construction site monitoring, tunnelling and blasting. The IP 65-rated case contains a lead-acid battery which operating time can be easily extended by connecting an external battery or small solar panel. The intelligent charging unit enables use of a solar panel without expensive controllers and heavy batteries.

The case is fitted with very robust, waterproof connectors (military standard) and comes with an IP 65 external power supply. The system uses a low-noise, hermetically sealed tri-axial piezoelectric accelerometer enabling the outdoor use without additional enclosures. The accelerometers’ signal ground is insulated from the mounting surface and outer case to prevent ground loops. All accessories fit conveniently into a second carrying case.

SVAN 958A

SVAN 958A Class 1 Four-channel Sound & Vibration Analyser is dedicated for all applications that require simultaneous class 1 sound and vibration assessment. Each of four input channels can be independently configured for sound or vibration detection with different filters and RMS detector time constants giving users an enormous measurement flexibility.

The real advantage of SVAN 958A is the capability to perform advanced analysis simultaneously to the level meter mode. In practise this allows the user to obtain broad-band results such as Leq, RMS, LMax, LMin, LPeak together with four-channel analysis like FFT or octave band analysis.

List of available analyser functions includes FFT, 1/1 or 1/3 octave, cross spectra, sound intensity, RT 60 and more. The 4-channel time-domain signal recording to .wav format is available as well as an exceptional feature! All measurement results are stored in non-volatile 32 MB internal memory or USB memory stick and can be easily downloaded to a PC with SvanPC++ software. SVAN 958A with RS 232 interface (SV 55) can be offered with GPRS modem or LAN & WLAN connection module. Together with SvanPC++_RC remote communication software, these interfaces provide easy remote access to instrument settings & data over Internet and local area network. Instrument is powered from four AA standard or rechargeable batteries as well as from the external DC power source or USB interface. Robust case and light weight design accomplish the exceptional features of this new generation instrument.

SVAN 977A

The SVAN 977A is a Class 1 Sound and Vibration meter designed for occupational and environmental measurement applications. The SVAN 977A is a successor of SVAN 977 offering bigger memory 8 GB and the Bluetooth® interface as a software option that can be enabled at any time. The meter provides broad-band results such as Leq, Max, Min and Peak with all standard weighting filters together with an incredible time-history logging feature with two adjustable logging steps.
One unique feature of the SVAN 977A is ultrasound measurement band up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Ultrasound is used in a number of industrial processes such as cleaning, drilling or welding as well as hospitals for medical procedures.
The built-in Bluetooth® interface together with smart-phone application, SvanMobile, extends measurement capabilities with all the features offered by smartphones including text/voice comments, photo, video, GPS position etc.

With the option of time signal recording SVAN 977A can record the raw signal samples with defined frequency up to 48 kHz. Analysis of the raw signal is used whenever frequency analysis is not sufficient. Post-processing of high quality wave files (48 kHz, 24 bit) such as calculation of tonality is available in SvanPC++ program. Time signal is recorded in a wave format which means that it can be played back in the PC software and used for noise source recognition (audio recording).

The SVAN 977A kit consists of SVAN   977A Class 1 sound & vibration level meter with a detachable preamplifier SV 12L and high quality omni-directional SV  7052E microphone, compliant to IEC61094-4. The list of accessories includes: SA 143 carrying case, SA  22 windscreen, 8 GB microSD card, four AA batteries, USB cable, and CD with user manual. Each SVAN     977A has its factory calibration certificate and 36 months warranty card.

With an optional microphone and 1/3 octave or FFT analysis SVAN    977A provides analysis of the ultrasounds up to 40 kHz. The ultrasound band is normally considered as the frequency range above 20 kHz. Limits of permissible ultrasound levels are usually expressed in terms of Leq and Max values specified in 1/3 octave bands for 20 kHz, 25 kHz, 31.5 kHz and 40 kHz.
