A TEDS contams the cntical information needed by an instrument ormeasurement System to identify, characlehze, interface, and property use the signal from an analogue sensor The TEDS r黩sides in embedded memory, typically an EEPROM, within the analogue transducer. as defmed m the IEEE 1451.4 standard. IEEE 1451.4 defmes the method of encoding TEDS information fora 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 utilizes the concept of tempiates that define the spcifie properlies for diffrent sensor types. Each GRAS TEOS microphone is a combination of a TEDS-enabled preamplifier and a microphone cartndge which is sealed with a stK.ker The TEDS is programmed to store the calibration information for the sp驩cifie combination usmg IEEE 1451 4 TEDS temptate number 27: microphone with built-in preamplifier 1 Trnn^ucrr EUtfrwik Data m pmpovd by IEEE-PU51 .4
