SOUND MEASUREMENT DEVICES
Sound Level Meter
The XL2 measurement microphone comes with an accurate sound level meter for monitoring live sound events and environmental noise. For example, parameters such as real, L, Leq, Lmax, Lmin are measured with the same weight A, C, Z and time measurements F and S frequency. All measurement results are available at the same time.
Customers can log all acquired level information onto a portable Mini-SD card with real-time information. In addition, the XL2 also offers a wav file recording for a complete document of measured sound pressure levels, where voice memos can be added for each measurement. XL2 accuracy exceeds IEC 61672-1, class 1. According to DIN 15905-5 and SLV 2007, the XL2 measures correction values between the point of sound of their experience and the actual measuring positions.
Extended Acoustic Pack (optional)
The Extended Acoustic Pack offers metrics and acoustic-volume additional features for:
Percentile: 1%, 5%, 10%, 50%, 90%, 95%, 99%
Time weight: Pulse
Sound Pressure Level L Ieq, Sound Exposure Value L AE
Clock-Impulse Maximum Level (TaktMax) and 45645-1 values Digital I/O interface files specified in DIN-Recording and WAV (24 bit, 48 kHz) range from 5 Hz to 20 High resolution Zoom Hz, FFT 0.4 kHz 1 / 3 Reflection time RT60 octave resolution
Real Time Analyzer RTA
The RTA perfectly suits its tasks, such as optimizing sound systems. In addition to the broadband parameters, the XL2 measures both parallel real-time spectrum in 1/1 or 1/3 octave band solution according to IEC 61260 class 0.
FFT Analysis
Real-time FFT effects and narrowband filter combs are one of the ideal tools for visualization. It measures the average level of the ranges Leq – 7 Hz to 20 kHz and the actual level It measures. The Acoustic Package offers an additional kHz high-resolution Zoom-Hz – 20 FFT Extended frequency range of up to 5 Hz in steps of up to 0.4 Hz optionally.
RT60 Reflection Time
The XL2 bands decay energy in 63 measures in the range from 8 kHz to 8 Hz by Schroeder in the 1/1 octave method. Automatic triggering and multiple averaging of measurements simplifies and minimizes measurement time. The test pulse signal serves as the source of either a pink noise or a door. Optional Extended Acoustic Pack extends resolution 1/3 octave for RT60 measurement.
Polarity
The same polarization will be important for the image sound stereo left and right speaker. XL2 measures speaker cabinets and polarity cables, single speaker. The detailed result page displays the measured Poles from groups of 125 octaves from 8 to 8 kHz. This provides in-depth verification of the relationship of polarity – frequency. nti Audio Test CD provided with test generator Minirator test signal or service polarity signal as signal.
Delay Time
The delay function will suit the correct setup of delay line arrangements, thus optimizing the direction of the signal source. The XL2 measures the time between the electrical reference signal and the speaker acoustic signal. Required acoustic delay settings are displayed automatically so that the sound engineer can determine the delay time measured directly from the rack delay device.
Speech Intelligibility STI-PA (optional)
STI-PA function measures speech intelligibility in the latest system public disclosure according to the standard IEC 60268-16:2003 revision. The XL2 displays seven octave levels of individual and modulation indices by group measurement results as accompanying results STI or CIS. The specific STI-PA test signal generated by the measurement results is obtained.
STI-PA Test incl. CD
Minirator MR-PRO, compatible with systems inputs for audio, required generator test signal
NTI Audio Talkbox is the necessary acoustic signal generator, thus measuring the full signal, the audio chain for sound systems with microphones.
Analogue Audio Analyzer
Featuring a balanced XLR and unbalanced RCA analyzer with combined inputs, the XL2 is a comprehensive soundstage. This frequency meter offers level, distortion (THD + N) and simultaneous monitoring. Built-in speaker or headphone output or test signal audible monitoring offers only distortion residual listening. Optimized low distortion and low noise design tools allow unique measurements down to -112 dB level to -100 dB, and lower often residual distortion.
Scope
The scope function visualizes the signal of electrical input waveform. Automatically selects the X-axis (time) and Y-axis scaling (for frequency fundamental triggers and level accordingly). The dominant basic or max frequency screen coverage is not displayed
ULTRASONIC DETECTOR
Compressed air leaks are energy thrown into the street. Ultrasonic detector detects air leaks even in the loudest environments and turns the compressor room into a profitability center. In addition, vacuum leaks, trap and valve leaks, gas leaks, electric arcs and coronas are also detected with the same detector.
Ultrasonic technology also provides economical devices with high precision measurement for predictive maintenance and quality control automation.
SDT is one of the leading international companies producing ultrasonic measuring devices in the world. Beneath its success are effective solutions to specific problems.
Automatic Quality Control Throughout Production
Continuous quality control reduces overall costs, increases net work time and prevents material loss. SDT has also developed applications in the following flight tests.
– Vapor sealing on valves
– Sealing in headlights, steel rims, gearbox (with pressure test)
– Sealing (by bubble test) in tubes, heat exchangers, filters, valves
– Detection of disturbances in acoustic resonance
– Detection of abnormal noise and vibrations in engines
Predictive Maintenance
SDT has also developed ultrasonic solutions for the following mechanical problems such as tearing and abrasion.
- Fast and slow spherical bearings, rotating brushes, gears, valves, injectors and shears
More advanced applications can also test the following.
- Unusual parasitic vibrations in machines
- Operation of pumps, motors, turbines and gearboxes
Exact measurements can be taken
- Contact or non-contact temperature control
- Detection of contact or non-contact rotational speed
- Determining the sound level
- Air mass flow
Sealing Measurement
The best way to make sure the leak is tight is to ultrasonically test it. The test is built into your production process or used later for control purposes. In order to understand the best exact result, SDT uses a device that can detect naturally occurring ultrasonic sounds as well as detect these sounds by broadcasting them with an external transmitter.
The model of SDT, which broadcasts with an external transmitter, can be used in many areas from large volume buildings to rooms in pilot cabins, from vehicles to electrical cabins.
The device is also very useful for measuring tightness in water tanks and underground petrol tanks. SDT also measures the pressure inside the tanks.
Leak Detection
Air leakage means loss in every sector. Leakage means product loss in water and fluid pipes, while in compressed air systems it means increased energy costs due to heat and pressure loss in steam pipes and heating devices.
SDT is effective in solving problems that may occur in the places listed below.
Oxygen and compressed air, steam and gaseous fluid circuits, valves, jacks and turbines
Heat Exchangers, gearbox, pump, condenser, boiler, air distribution pipe
In inflatable materials (boats, etc.)
Pressure drops, vacuums
Detection of electric arcs (transformer, relay, circuit breaker etc.)
