“…Due to these unique properties, they can be used in any of the above mentioned critical applications [1]- [4]. We can achieve this through the merits and unique qualities of FBG, which can be utilized to measure various physical parameters such as temperature, pressure, liquid density, strain, and liquid level, among others [5]- [7]. As a result, the design and manufacture of novel types of pressure sensors is gaining attraction in the research community.…”

Pressure sensors are used in various industrial applications assisting in preventing unintended disasters. This paper presents the design and fabrication of a novel Seesaw device incorporating a diaphragm and Fiber Bragg Grating (FBG) sensor to measure the pressure of liquids. The designed sensor has been tested in a static water column. The proposed design enables the user to easily make and modify the diaphragm based on the required pressure range without interfering with the FBG sensor. The developed pressure sensor produces improved accuracy and sensitivity to applied liquid pressure in both low and high-pressure ranges without requiring sophisticated sensor construction. A finite element analysis has been performed on the diaphragm and on the entire structure at 10 bar pressure. The deformation of the diaphragm is comparable to theoretical deformation levels. A copper diaphragm with a thickness of 0.25 mm is used in the experiments. All experiments are performed in the elastic region of the diaphragm. The sensor's sensitivity as 19.244 nm/MPa with the linearity of 99.64% is obtained based on the experiments. Also, the proposed sensor's performance is compared with recently reported pressure sensors.

“…There is a linear relationship between SG and density, hence Brix measurement can be done through one of these two quantities [ 4 ]. SG or density can be measured using various methods, such as hydrometer principle [ 5 ], optical methods based on refractive index [ 1 ] or infrared absorbance, near-infrared spectroscopy, X-ray absorption, ultrasonic method [ 6 ], fibre Bragg grating [ 7 ], mass flow of liquid based on Coriolis principle [ 8 ], differential pressure measurement [ 9 ], or biosensing [ 10 ].…”

This paper presents a Brix sensor based on the differential pressure measurement principle. Two piezoresistive silicon pressure sensors were applied to measure the specific gravity of the liquid, which was used to calculate the Brix level. The pressure sensors were mounted inside custom-built water-tight housings connected together by fixed length metallic tubes containing the power and signal cables. Two designs of the sensor were prepared; one for the basic laboratory testing and validation of the proposed system and the other for a fermentation experiment. For lab tests, a sugar solution with different Brix levels was used and readings from the proposed sensor were compared with a commercially available hydrometer called Tilt. During the fermentation experiments, fermentation was carried out in a 1000 L tank over 7 days and data was recorded and analysed. In the lab experiments, a good linear relationship between the sugar content and the corresponding Brix levels was observed. In the fermentation experiment, the sensor performed as expected but some problems such as residue build up were encountered. Overall, the proposed sensing solution carries a great potential for continuous monitoring of the Brix level in liquids. Due to the usage of low-cost pressure sensors and the interface electronics, the cost of the system is considered suitable for large scale deployment at wineries or juice processing industries.
