通過(guò)與客戶的密切合作，我們知道數(shù)據(jù)安全非常重要，因?yàn)榕c不合適和不可靠的傳感器相關(guān)的成本可能決定您的項(xiàng)目是否成功。
對(duì)于我們的用戶，數(shù)據(jù)安全性可直接轉(zhuǎn)換為更輕松選擇麥克風(fēng)，簡(jiǎn)化系統(tǒng)配置和減少測(cè)量誤差的請(qǐng)求。
外形尺寸
為了滿足這些要求，我們發(fā)明了麥克風(fēng)套裝概念。它簡(jiǎn)單，可靠，堅(jiān)固，由麥克風(fēng)盒和前置放大器組合而成，可作為一個(gè)單元進(jìn)行校準(zhǔn)。這消除了錯(cuò)誤，因?yàn)橹恍枰紤]一個(gè)靈敏度值，并且消除了污染接口的風(fēng)險(xiǎn)。將其與我們*且經(jīng)過(guò)驗(yàn)證的設(shè)計(jì)相結(jié)合，您擁有當(dāng)今業(yè)界可靠的測(cè)量麥克風(fēng)套件。
典型應(yīng)用和使用
46BH-1是壓力麥克風(fēng)套件，因此優(yōu)化用于閉合耦合器中聲源的聲學(xué)測(cè)量或邊界或墻壁處的聲壓測(cè)量; 在這種情況下，麥克風(fēng)形成墻壁的一部分并測(cè)量墻壁本身的聲壓。
關(guān)于溫度范圍，請(qǐng)參閱規(guī)格。如果需要更高的溫度限制，我們建議考慮使用GRAS探頭麥克風(fēng)，其中麥克風(fēng)和前置放大器可以與熱源隔離。
設(shè)計(jì)
GRAS 46BH-1是一款高性能標(biāo)準(zhǔn)麥克風(fēng)套裝。在我們的潔凈室環(huán)境中，裝置組裝并用標(biāo)簽密封。但是，如果您希望單獨(dú)使用這些組件，則可以卸下麥克風(fēng)組件。
麥克風(fēng)
麥克風(fēng)盒是高質(zhì)量的IEC 61094 WS3F標(biāo)準(zhǔn)化GRAS 40BH 1/4“外部極化壓力麥克風(fēng)，專為在多種環(huán)境中的長(zhǎng)期可靠性而設(shè)計(jì)。
前置
放大器前置放大器是GRAS 26AC-1前置放大器，它包含TEDS并基于我們*的電路板基板。在業(yè)界，這些產(chǎn)品以其低自噪聲，寬頻率和出色的壓擺率性能而聞名。
兼容性
為了按照規(guī)定執(zhí)行，GRAS 46BH-1麥克風(fēng)套件需要一個(gè)電源模塊或分析儀輸入，可為前置放大器提供電源和200 V極化。如果電源較低，則驅(qū)動(dòng)長(zhǎng)電纜的能力降低，因此降低了上限頻率。如果電壓較低，則會(huì)影響較高的動(dòng)態(tài)范圍。
麥克風(fēng)套件采用5針mini-LEMO連接器端接。隨時(shí)可以使用帶有各種類型和長(zhǎng)度的LEMO連接器的電纜組件，可提供標(biāo)準(zhǔn)長(zhǎng)度和定制長(zhǎng)度。
46BH-1是IEEE 1451.4 TEDS 27v。符合1.0。如果您的測(cè)量平臺(tái)支持傳感器電子數(shù)據(jù)表，您將能夠讀取和寫(xiě)入屬性和校準(zhǔn)數(shù)據(jù)等數(shù)據(jù)。
系統(tǒng)驗(yàn)證
TEDS的功能對(duì)于確定哪個(gè)麥克風(fēng)連接到哪個(gè)輸入通道非常有用。但是，不是檢查麥克風(fēng)是否符合規(guī)格。對(duì)于每日驗(yàn)證和檢查您的測(cè)量設(shè)置，我們建議使用GRAS 42AB Sound Calibrator 等聲源。
為了進(jìn)行適當(dāng)?shù)撵`敏度校準(zhǔn)，我們建議使用GRAS 42AP智能活塞式電源等參考聲源。
校準(zhǔn)
出廠時(shí)，所有GRAS麥克風(fēng)均已在受控實(shí)驗(yàn)室環(huán)境中使用可追溯校準(zhǔn)設(shè)備進(jìn)行校準(zhǔn)。根據(jù)使用情況，測(cè)量環(huán)境和內(nèi)部質(zhì)量控制程序，我們建議每年至少重新校準(zhǔn)一次麥克風(fēng)。
我們提供兩種校準(zhǔn)作為可選的售后服務(wù)：GRAS可追溯校準(zhǔn)和GRAS認(rèn)可校準(zhǔn)。
GRAS可追蹤校準(zhǔn)是由受過(guò)培訓(xùn)的人員根據(jù)既定程序和標(biāo)準(zhǔn)在受控條件下執(zhí)行的可追溯校準(zhǔn)。這與所有GRAS麥克風(fēng)作為我們質(zhì)量保證*的一部分的嚴(yán)格校準(zhǔn)相同。

Technology
Introduction
Through a close cooperation with our customers, we know that data-safety is highly important because the costs related to unsuited and unreliable sensors may determine whether your project turns into a success or not.
For our users, data safety translates directly into requests for easier microphone selection, simple system configuration and reduction of measurement errors.
To meet these requirements, we invented the microphone set concept. It is simple, reliable and robust and consists of a microphone cartridge and preamplifier combination, which is calibrated as one unit. This eliminates errors because there is only one sensitivity value to account for and the risk of contaminating the interface is eliminated. Combine this with our unique and proven design and you have the most reliable measurement microphone sets available in the industry today.
Typical application and use
The 46BH-1 is a pressure microphone set and as such optimized for acoustic measurements of the sound source in a closed coupler or the measurement of sound pressure at a boundary or wall; in which case the microphone forms part of the wall and measures the sound pressure on the wall itself.
Regarding temperature range, see the Specifications. Should higher temperature limits be required, we recommend considering the GRAS probe microphones where the microphone and preamplifier can be isolated from the hot source.
Design
The GRAS 46BH-1 is a high-performance standard microphone set. In our clean-room environment the set is assembled and sealed with a label. However, the microphone set can be dismounted, if you wish to use the components separately.
Microphone
The microphone cartridge is the high-quality IEC 61094 WS3F standardized GRAS 40BH 1/4" Externally Polarized Pressure Microphone, designed for long-term reliability in multiple environments.
Preamplifier
The preamplifier is the GRAS 26AC-1 Preamplifier which is inclusive TEDS and based on our well-known circuit board substrates. In the industry these are famous for their low self-noise, wide frequency and excellent slew rate performance.
Compatibility
To perform as specified, the GRAS 46BH-1 microphone set requires a power module or an analyzer input which can supply the preamplifier with power as well as 200 V polarization. If the power supply is lower, the capability of driving long cables is reduced and consequently the upper frequency is reduced. If the voltage supply is lower it will influence the upper dynamic range.
The microphone set is terminated with a 5-pin mini-LEMO connector. Ready to use cable assemblies with LEMO connectors of various types and lengths are available in standard as well as customized lengths.
The 46BH-1 is IEEE 1451.4 TEDS 27v. 1.0 compliant. If your measurement platform supports Transducer Electronic Data Sheets you will be able to read and write data like properties and calibration data.
System verification
The functionality of TEDS is very useful to determine which microphone is connected to which input channel. However, it is not a check of whether the microphone is within specifications or not. For daily verification and check of your measurement setup, we therefore recommend using a sound source like the GRAS 42AB Sound Calibrator.
For proper sensitivity calibration we recommend using a reference sound source like the GRAS 42AP Intelligent Pistonphone.
Calibration
When leaving the factory, all GRAS microphones have been calibrated in a controlled laboratory environment using traceable calibration equipment. Depending on the use, measurement environment and internal quality control programs we recommend that the microphone is recalibrated at least once a year.
We offer two kinds of calibration as an optional after-sales service: GRAS Traceable Calibration and GRAS Accredited Calibration.
GRAS Traceable Calibration is a traceable calibration performed by trained personnel under controlled conditions according to established procedures and standards. This is identical to the rigorous calibration that all GRAS microphones are subjected to as an integral part of our quality assurance.
GRAS Accredited Calibration is performed by the GRAS Accredited Calibration Laboratory that has been accredited in accordance with ISO 17025 by DANAK, the Danish Accreditation Fund.
If you want a new microphone set delivered with an accredited calibration in stead of the default factory calibration, specify this when ordering.
Learn more at gras/calib.
Quality and warranty
GRAS microphone sets are made of components from our proven standard portfolio and are all manufactured of high-quality material and branded parts that were chosen and processed to ensure life-long stability and robustness.
All parts are manufactured and assembled at the factory in Denmark by skilled and dedicated operators in a verified clean-room environment. The microphone diaphragm, body and unique protection grid are made of high-grade stainless steel and make the microphone set resistant to physical damage as well as corrosion caused by aggressive air or gasses.
This, together with the enforced gold-plated microphone terminal guarantees a highly reliable connection. Thanks to the high quality, our warranty against defective materials and workmanship is 5 years.
Service
Should you by mistake damage the diaphragm on a GRAS microphone we will in most cases be able to exchange it at a very reasonable cost and short turn-around time. This not only protects your investment but also meets your quality assurance department since you do not have to worry about new serial numbers etc.
