The new B45 series of intelligent optical sensors from ABB Control is designed to offer maximum versatility and ease of use for a wide variety of control applications.
Flexible bar code scanner designed to adapt
Thanks to the Adaptascan's autofocus capability and WindowsT-based configuration software, changes in focus, scan pattern, label format and communication requirements can be made on-line.
With a guaranteed total error band (all possible errors) of less than +/-0.01% full-scale, high resolution and an inherent tolerance to overpressure and pressure spikes, the Precise sensor offers a level of performance claimed to be unequalled by any other pressure sensor.
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.

For its versatile, high speed reading or decoding of linear and 2D codes on flat work and cartons within a depth of field of 50mm, the new AV1200 from Accu-Sort may be unmatched.
"The challenge has been to combine mathematics, mechanics and electronics in a way that optimises the attributes of the technology", states Presens' Chief Technical Officer, Bjorn Erik Seeberg.
Seeberg continues: "Throughout the development process, our goal has been to achieve a total error band of less than +/-0.01% full-scale".
"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".
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% full-scale".
"Combined with its tolerance to noise, vibration, overpressure and pressure spikes, we are certain that we have developed a unique product that fills a large void in the market".
He adds: "Although we have completed development of Precise, we will not rest on our laurels".
"The knowledge and experience gained in developing Precise will be used to generate new development".
"For example, we now know that +/-0.005% full-scale is within reach".
"If we can additionally increase both the pressure area and speed of the sensor, we will be entering exciting, uncharted territory".
At the heart of the Precise sensor is the company's proprietary patented technology.
In comparison with 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.
