Displacement Transducer FSK

MEASURES AND DETECTS DEFORMATIONS OF ANY
STRUCTURE WITH THE POWERED TRANSDUCER POWERED BY BATTERY.

GENERAL OVERVIEW

Extremely reliable, compact and powered by long-life batteries, the Transducer developed by Filippetti Group is a device for the advanced monitoring of cracks or the acquisition of data during structural investigations and on-site tests.

Typical examples of the applications are the load tests on slabs or on foundation piles, bearing tests on land or tests on masonry with flat jacks. Equipped with a UHF wireless communication module (FSK modulation), in accordance with current regulations, and integrated with the Filippetti Group’s own architecture (Hardware: Smart Network, Software: IoT Smart Platform), this solution allows remote monitoring of the building conditions in real time.

 

MAIN ADVANTAGES

  • Easy installation – thanks to the battery power supply, the device can be easily installed in the application sites, without the need for extraordinary interventions (e.g. to feed through the power cord);
  • Long range and low consumption – thanks to the integration of a UHF wireless module, the device can transmit data for hundreds of metres without compromising battery life;
  • Measurement accuracy – the system allows the measurement of deformations of the order of nanometres;

OPERATING PRINCIPLES

COMMUNICATION: SMART NETWORK PROTOCOL

Via UHF wireless communication (FSK modulation) with a gateway Smart Network, you can monitor in real-time values measured by the transducer of shift.

SPECIFIC MEASURES: DEFORMATION

The device, including the potentiometric transducer, is used to measure the deformation gradient – compared to a suitably set initial state – of any object in direct contact with the transducer itself (for example, for measurements of deformation). The data that is sent to the Smart Network is the raw live value read by the 16-bit analogue digital converter (ADC), integrated on-board. At the software level, this value is then converted to the actual displacement value, by application of appropriate regression curves, where the coefficients are known and vary according to the transducer used.

POWER SUPPLY: by BATTERY

The node is powered by 3 batteries, type AAA, of 1.25 Ah (with a nominal voltage of 1.5V each).
