Identification system simplifies
measurement
Two types of intelligent transducer identification system remove possible errors caused by manually entering parameters when configuring a measurement system.
HBM has launched two types of intelligent transducer identification system to remove possible errors caused by manually entering parameters when configuring a measurement system Called T-IDTM (Transducer Identification) and TEDS (Transducer Electronic Data Sheet) the systems are based on an identification module in the transducer that enables both the analogue measurement signal and the transducer data, stored in digital format, to be retrieved without the need for any additional wiring

Amplifier increases press-fit assembly accuracy
A measurement amplifier simplifies two-channel manufacturing and testing processes, such as press-fit monitoring, to ensure greater fitting accuracy.
Measurement consistency improved for torque
Improvements made to torque measurement equipment enable all SG full bridge amplifiers to be used for torque measurement and measurement shafts also benefit from a rotational measuring system.
In the T-IDTM system, the transducer is assigned a unique ID number that is recognised by HBM's integrated database software to automatically configure the amplifier so that it is ready to take measurements.
In the TEDS system all the data required for configuring the measurement system is stored in the transducer.
This file system has a format and hierarchy that complies with the pending international IEEE 1451.4 standard.
Both transducer types feature identical connections and amplifier hardware requirements.
HBM has applied for a patent for its transducer identification systems.
Engineers have wanted to be able to connect transducers and start accurate measurements with minimum delay for some considerable time.
An important step in setting up a transducer is to ensure that the correct parameters needed for converting the measurement into physical units are entered in the transducer.
Without the intelligent transducer these have to be entered manually and errors can easily occur leading to measurement errors that may not be detected.
The intelligent transducer largely eliminates this source of errors.
Connector plates for HBM's modular MGCplus amplifier system are available that can read the T-IDTM or TEDS transducer data and catman4.5, the latest version of HBM's data acquisition software, holds the transducer database needed for the T-IDTM system.
An example of an application where the technology has proved important is in the use of strain gages (SG) for structural tests on aeroplanes.
The identification module is incorporated either in the cable or is available as a chip that can be bonded to the test object directly in front of the strain gage measuring point.
Within the transducer, the identification module can be fitted into the transducer housing, cable or connector. Request a free brochure from HBM UK ...
