Experiments are done to quantify cause-and-effect relationships between adjustable parameters (inputs, factors, x) and the results (outputs, responses, y). They help to answer questions like: How do the ingredients and proportions of a mixture (inputs) influence its properties (outputs)? How…
Alicat Scientific This company’s new, rechargeable, portable gas-mass flowmeters (photo) feature reading accuracy of ±0.8% with 18 h of continuous operations available on a single charge. These meters feature rapid multi-parameter measurements capable of producing live readouts of mass and…
The M12TX temperature transmitter (photo) features a sensor with a built-in programmable transmitter, molded connector, 4–20-mA output and a –50 to 500°C temperature range. The probe is ideal for areas where traditional head connections are too large to fit. The…
CD-adapco (London, U.K.; www.cd-adapco.com), the largest privately held CFD (computational fluid dynamics) focused provider of computer-aided-engineering software, has released STAR-CCM+ v9.06. The new release allows engineers to get simulations closer to the final product by accounting for factors that are…
It is good to see your magazine publishing articles highlighting the tangible benefits that process control is capable of bringing to the chemical process industries [Advanced Control Methods for Combustion, Chem. Eng. September, 2014, pp. 34–39]. While the authors seem…
What are the steps to finding the best pressure sensor for a particular application? That’s a challenge faced by many a young engineer just out of school. Engineering school teaches a great deal of theory, but what is the best…
Pressure transmitters are widely used throughout the chemical process industries (CPI). Although pressure in and of itself is an important process parameter, differential pressure (DP) measurements enable the inference of other important parameters as well. This article presents a concise…
Danray Products The Axioline F I/O system has been extended with the addition of five particularly compact analog I/O modules. The new modules, which are just 35 mm wide, each offer four channels for tailor-made selection of analog functions in…
Bürkert Fluid Control Systems The modular multichannel multiCELL transmitter/controller type 8619 is a customizable measuring system with an extended range of functionalities that can work with multiple types of sensors. Previously available only for panel installation, there is now a…
Yokogawa With a 1-m spatial resolution, The DTSX 3000 Distributed Temperature Sensor can measure the temperature along fiber-optic cables up to 50 km in length, eight times the distance possible with the previous model. The DTSX 3000 is well suited…
