The underlying mechanism for plug and play identification is the standardisation of a Transducer Electronic Data Sheet (TEDS 1). A TEDS contains the critical information needed by an instrument or measurement system to identify, characterise, inter-face, and properly use the signal from an analogue sensor. The TEDS resides in embedded memory, typically an EEPROM, within the analogue trans-ducer, as defined in the IEEE 1451.4 standard.IEEE 1451.4 defines the method of encoding TEDS information for a broad range of sensor types and applications. In order to cover such a broad range while also keeping memory usage to a minimum, the IEEE 1451.4 TEDS concept utilises the concept of templates that define the specific properties for different sensor types.Instrumentation and software to read TEDS infor-mation directly from the transducer are available, for example, from National Instruments, OROS, etc.Each G.R.A.S. TEDS microphone is a combination of a TEDS-enabled preamplifier and a microphone cartridge which is sealed with a sticker. The TEDS is programmed to store the calibration information for the specific combination using IEEE 1451.4 TEDS template number 27: microphone with built-in preamplifier.The G.R.A.S. ½-inch TEDS microphones described in this document are a combination of various ½-inch microphone cartridges and one of the following ½-inch TEDS-enabled preamplifiers:• Preamplifier Type 26TK with: with a 7-pin LEMO connector, see Fig. 2• CCP 2 Preamplifier Type 26CA with:with a BNC co-axial connectorTypical features/applications¦ Single unit comprising microphone cartridge and TEDS 1-enabled preamplifier¦ Stability¦ Plug and play¦ Precision acoustic measurements½-inch Microphone SetsFig. 1 ½-inch Microphone SetsVer 01 March 20111 Transducer Electronic Data Sheet - according to IEEE-1451.4Fig. 2 7-pin LEMO connector 1B male (ext. view)2 Constant Current Power.100 kHz10 kHz1 kHz100 HzDecibels re. level at - 12- 10- 6 0 20 º10 Hz- 2- 4- 8- 2 -½-inch Microphone SetsFrequency response:3.15 Hz - 20 kHz: . . . . . . . . . . . . . . . . . . . . .± 2.0 dB5 Hz - 10 kHz: . . . . . . . . . . . . . . . . . . . . . . . ± 1.0 dBNominal sensitivity:50 mV/PaPolarization voltage:200 VDynamic range:Upper limit (3 % distortion): 146 dB re. 20 µ PaLower limit (thermal noise): . . . 17 dBA re. 20 µ PaOutput impedance:Typical:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55 ?Power supply:Single:. . . . . . . . . . 28 V (0.7 mA) to 120 V (2.5 mA)Dual: . . . . . . . . . ± 14 V (0.7 mA) to ± 60 V (2.5 mA)Maximum signal-output voltage (peak):from ± 10 V to ± 50 VTemperature:Operation:. . . . . . . . . . . . . . . . . . . .– 30 oC to + 70 oCStorage:. . . . . . . . . . . . . . . . . . . . . – 40 oC to + 85 oCCoefficient (250 Hz): - 0.007 dB / °CRelative humidity:Operation:. . . . . . . . . . . . . . . . . . . . . . . . . .0 to 95 %Storage:. . . . . . . . . . . . . . . . . . . . . . . . . . . .0 to 95 %Influence (250 Hz): . . . . . . . . . . . . . . . . . . . .< 0.1 dBStatic-pressure coefficient:- 0.01 dB / k PaInfluence of axial vibration, 1 m/s2:63 dB re. 20 µ PaConnector:LEMO: . . . . . . . . . . . . . . . . . . . .7-pin 1B male plugDimensions and weight:Diameter: . . . . . . . . . . . . . . . . . . . . . . . . . . 13.2 mmLength: . . . . . . . . . . . . . . . . . . . . . . . . . . . . .100 mmWeight: . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40 gSpecifications Type 46AFFig. 3 Typical frequency response of Type 46AF.
