Sens-in® System
Towards the end of 2015 we imagined what the vine of the future would be.

Background

Founded in 1950, Poggipolini S.p.A. is a leading Italian company, expert in the design and production of critical and structural fasteners and precision parts, as well as systems for the aerospace, space, defense and automotive (hypercar and F1) industries.

We provide advanced engineered fastening solutions.
In 2020 Poggipolini founded Sens-In Srl, a spin-off of Poggipolini.

Why we use strain gauges

Tech

comparisons:

Precision and Direct Measurement

1- Strain gauges provide a direct and precise measurement of bolt deformation, ensuring accurate clamp load readings. 

2- Ultrasonic methods estimate load based on sound velocity in the material, which can be affected by temperature, surface inconsistencies, and environmental factors. 

3- Pin gauges only offer an indirect assessment by checking hole dimensions without measuring actual load.

Greater Reliability in Critical Environments

1- Strain gauges are also more reliable in high-temperature or dynamic load environments. 

2- Ultrasonic readings can be less accurate due to thermal variations. 

why we use strain gauges

Reduction of Margin of Error

1- Strain gauges operate independently of surface conditions.

2- Ultrasonic measurements can be prone to human error from transducer positioning and calibration. 

3- Pin gauges provide only a subjective fit assessment.

Seamless Integration with Control Systems

1- Strain gauges can be integrated with digital monitoring and predictive maintenance systems, enabling real-time data collection and analysis to enhance safety and reduce maintenance costs.

2- Ultrasonic methods require an operator for measurements. 

3- Pin gauges are purely mechanical tools with no digital capabilities.
