  • Page 93 Appendix C – Transducer Electronic Data Sheets (TEDS) Smart Sensors Certain types of transducers are classified as smart sensors. They contain a Smart Transducer Interface Module (STIM), which in turn, contains an onboard EEPROM memory IC, called TEDS, Transducer Electronic Data Sheet. (See Figure C.01.) The TEDS electronically stores information regarding the transducer’s characteristics and parameters such as type of device, manufacturer, model number, serial number, calibration date, sensitivity, reference frequency, and other data.
  • Page 94 Class 1 interface Current Plug-and-play sensor source Analog signal Fig. C.02. Class 1 sensors have only two leads that Sensor connect to the input of the STIM. The analog signal Digital voltage and any required biasing voltage share the signal TEDS EEPROM same pair of leads.
  • Page 95 System Architecture The IEEE has partitioned the P1451 standard into five major parts. Each part addresses a different facet or interface of the project that enables sensor manufacturers to design and build new sensors compatible with all networks. Each part is defined as follows: Part 1.
  • Page 96 The Basic TEDS contains the manufacturer’s identification, model identification, version letter, and the serial number, which are common to all types of sensors. The Standard TEDS, however, contains data unique to the sensor’s principle of operation. For instance, a piezoelectric accelerometer differs from a strain gage load cell, so the Standard TEDS EEPROM contains some common and some unique information.

  • Page 99 Trigger For IOtech 640 and 650 Series devices, “trigger” refers to a software event that starts a scan or marks an instant during an acquisition. Transistor-Transistor Logic (TTL) is a circuit in which a multiple-emitter transistor has replaced the multiple diode cluster (of the diode-transistor logic circuit); typically used to communicate logic signals at 5 V.
