Presens Creates a Technology Shift in Pressure Measurement

The Norwegian pressure sensor company, Presens AS, announces the launch of their new PRECISE pressure sensor. With a guaranteed total error band (all possible errors) within ±0.01%FS, high resolution and an inherent tolerance to over-pressure and pressure spikes, the PRECISE sensor offers a level of performance unequalled by any other pressure sensor.

The road to success
Since their first commercial installation in 1998, Presens has worked towards achieving their goal of developing the world’s best pressure sensor. Through years of continuous development and refinement of their unique core pressure sensor technology, Presens has created a sensor with characteristics that enable countless new possibilities in pressure measurement.

“Throughout the development process, our goal has been to achieve a total error band within ±0.01%FS. To be on the safe side, we worked with several different solutions, therefore development has taken longer than we originally planned. Now that the PRECISE sensor is launched, we are absolutely certain that the product delivers as promised”, states Presens’ Chief Technical Officer, Bjørn Erik Seeberg.

Petter Eide, Product Manager of PRECISE, agrees,”PRECISE has been tested by several independent institutions, and they all agree that it is accurate to within ±0.01%FS. Combined with its tolerance to noise, vibration, over-pressure and pressure spikes, we are certain that we have developed a unique product that fills a large void in the market.”

Unique Patented Technology
At the heart of the PRECISE sensor is the compnay’s proprietary patented technology. In comparison to conventional silicon pressure sensors that use diaphragms with a piezoresistive resistor bridge to measure stress, Presens pressure sensors measure pressure-induced compressive stress with a piezoresistive Wheatstone bridge integrated in a tubular silicon structure.

The mechanical design of the sensing element makes it possible to develop extremely robust and sensitive sensor solutions, which is the key to operational benefits for the user.

The PRECISE features
• FS pressure range up to 0 - 2000 bar
• Total accuracy better than ± 0.01% FS
• 1-year drift less than ± 0.01% FS
• Over-pressure 1.5 x FS to 5 x FS (FS pressure dependent)
• Adjustable sample rate 5 to 25 samples/sec
• Resolution in electronics less than 1 ppm (≥ 20 bit)
• Shock & vibration resistant
• Robust, all-welded construction
