Transducer Conditioning Interface to PLC

TCI

The TCI (Transducer Conditioning Interface) is a highly customisable interface system that converts the analogue signal of a measurement performed by LVDT or HBT transducers in a signal compatible with most of the data acquisition analogue cards.

BENEFITS
  • easy to install as it is calibrated during the production based on the model of sensor being used
  • compatible with most of the sensors available on the market
  • highly customisable
  • reliable and sturdy
DESCRIPTION

TCI is a line of signal conditioning interfaces consisting of three models with either one, four or eight channels.

It has been developed with technical and functional specifications particularly suited to convert a position or a dimensional measurement, performed by LVDT or HBT transducers, in a signal compatible with most of the analogue data acquisition cards. The unit output provides a direct electric signal (voltage or current), proportional to the measurement value of the sensor connected in input.

The output signal can be acquired by PLC analogue cards to control and manage process automations and for further processing by SCADA supervision systems.

The TCI interfaces are PLUG&PLAY units and therefore are supplied already calibrated for the model of sensor being used. This ensures that the machine down times are drastically reduced as the installation and maintenance operations are simplified.
