ROTATING TORQUE SENSORS
RST SERIES

The RST- Series is our low range rotating torque
sensors that are available in eleven full scale ranges
of 10 through 30K inch pounds. The sensing element
incorporates bonded foil strain gages of the highest
quality along with coined silver slip ring and silver brushes
for data transmission. The WR2, Flexural Natural Frequency,
and Torsional Stiffness values as stated in the Dynamic
Characteristics box below, are approximate and the
tabulated data pertains to the torque pickup only, and
does not include the effects of couplings or other
rotating masses that would be part of a dynamic
system.

CAL-TEDS
Plug & Play Option

AD9 (9 PIN "D" Series) Connector attached to the end of a Load Cell or Torque sensor cable with a TEDS ( Transducer Electoric Data Sheet ) EPPROM. Used with a DPM-3 Load Cell Meter, the Load Cell and DPM-3 will self calibrate. This option is a real time saver. Learn about Plug & Play Smart Sensors.

Learn about Plug and Play Smart Sensors


What are Plug and Play Smart Sensors?

A Plug and Play Smart Sensor is a Sensor that is compliant to the IEEE 1451.4 Standard. TEDS, or Transducer Electronic Data Sheet, is a set of electronic data in a standardized format defined within the IEEE 1451.4 standard. This data specifies what type of sensor is present, describes its interface, and gives technical information such as sensitivity, bridge type, excitation, etc. This information is stored in an EEPROM chip attached to a sensor. By having this chip, the sensor can identify and describe itself to the network and or Smart Load Cell Meter, thereby easing automatic system configuration. Let's say you have a Transducer Techniques Load Cell or Torque Sensor with the the proper instrument IEEE 1451.4 enabled Load Cell or Torque Sensor could be swapped in, self-identify, and work appropriately.


What are the advantages of Plug and Play Smart Sensors?

Benefits that can be experienced now include:

  • Simplified troubleshooting
  • Reduced safety risks. It is no longer necessary to "climb on machines" for connection verification
  • Reduced costs for set-up and tear-down
  • No recalibration is needed when replacing sensors
  • The data acquisition system can recalibrate itself

Advantages that will be available in the future include:

  • Integration with wireless transceivers
  • Elimination of large lengths of analog wiring
  • Reduced installation, maintenance and upgrade costs of measurement and control systems
  • The opportunity to add intelligence to sensors

Can a legacy / non-TEDS sensor be converted to a TEDS "Plug and Play" sensor?

Yes. A legacy / non-TEDS sensor can be converted to a TEDS "Plug and Play" sensor. Transducer Techniques offers a CAL-TEDS service to convert your sensor to a TEDS "Plug and Play" compliant sensor. The service consists of a connector, recalibration and a programmed EEPROM. This will update a legacy / non-TEDS sensor to be capable of plugging into Transducer Techniques IEEE 1451.4 compliant DPM-3 Smart Load Cell Meter.


What is Virtual TEDS?

Virtual TEDS is an online library of data sheets developed by National Instruments (www.ni.com) that contain the same information that would be found in an EEPROM TEDS, but exist for sensors not containing the EEPROM. This would define Plug and Play capability for legacy / non-TEDS sensors. As a National Instruments Plug and Play Sensor Partner and a National Instruments Alliance Member, Transducer Techniques has contributed the data for all its sensors to the Virtual TEDS database.
