Bolt Shaped VIS-NIR Wireless Sensor for Industrial Fluid Monitoring (BOLTSENS)

Sector: Manufacturing

Total budget: €136,3k

Total Funding: €136,3k


This new sensor development is one step beyond the current Probe concept sensor from Atten2, Patent Application No. P201730848. The Probe sensor has already been developed and tested at laboratory (TRL4), and is now under redesign to be tested at real working conditions.

The Probe is a photonic sensor for in-line fluid monitoring that determines the oil degradation level through colour measurements. As the oil degrades and losses its properties, the transmittance value reduces (Figure 1) and it is a common indicator of the degradation process of the lurbicant. The sensor contains a white LED to illuminate the fluid sample and a RGB detector to perform the colour measurements.

Water is another important factor that contributes to oil degradation and reduces lubrication efficiency.

The new sensor will contain both a RGB detector and a NDIR (non-dispersive infrared) detector, with a peak wavelength sensitivity centred at 1450nm, which can be used to measure the water content.

About Boltsens

The Consortium

ATTEN2, Spain

In Atten2 we supply technology and engineering service solutions aimed at reducing the operational risk of our customers and monitoring their critical assets.

Our technology is based on optical sensors that allow the condition of different fluids to be measured, and especially lubricating oils, which in turn gives us information on the wear behaviour of the machines and the degradation of the fluids we monitor.

Our aim is to give our customers tangible value.
