Compound Pressure Transducers

In a compound pressure transducer, the sensor is zero-referenced to atmospheric pressure. In other words, the transducer has been calibrated to provide the zero-pressure output value at full vacuum range of -14.7 PSI (or -1 bar). Typically this is offered for low and medium pressure range, gauge referenced transducers (vented or sealed). It is possible to use a compound pressure range on higher pressures but the tolerances of the transducer, such as full scale error, may exceed the vacuum range of -14.7 PSI. It is not recommended to use compound pressure ranges higher than 500 PSI in order to maintain

Flow Meters In The Food Industry

In the food industry there are many processes in which gas flows or liquid flows need to be measured or controlled. Flow meters or flow controllers are used in aeration processes for beverages or ice creams and for dosing applications such as adding ingredients – like flavorings, colourants and aromas – in confectionery products. But besides food processing applications, flow control is also used in sterilization processes of packaging. In this blog I’ll share some applications stories in more detail: Flow controllers for additive dosing There is a huge variation in candy available on the market, each brand with its

Pressure And Temperature Compensation To Optimize Flow Control

Various external factors can have influence on the measurement accuracy and control stability of mass flow controllers. But what are the most common challenges in pressure and temperature control? And how can you fix these?Real-time pressure- and temperature compensation can be the answer. As a Gas Flow Technology Manager at Bronkhorst, I know that efficiency and yield in a process require a stable gas flow. This gas flow can be measured and controlled by a thermal mass flow controller. In this blog I will explain the challenges you can encounter in pressure and temperature control and share some tips on

Bi-Directional Pressure Transducers For Vapor Recovery

Core Sensors offers a variety of high quality bi-directional pressure transducers for use in low pressure vapor recovery operations. Unlike a unidirectional pressure transducer that can measure pressures from zero to a defined positive pressure (i.e. 0 to 70mBar), bi-directional pressure transducers measure both positive and negative pressure (i.e. -70mBar to +70mBar). Bi-directional pressure transducers are commonly found in Vapor Recovery Units (VRU’s) which monitor and recover light hydrocarbon vapors that collect at the top of oil and gas storage tanks. The positive end of the pressure transducers measurement range is used to monitor the increase in vapor pressure at

How Mass Flow Controller Can Support The Pharmaceutical Industry

Bronkhorst recently had a customer who needed support with the exact dosing of pharmaceutical excipients. This customer was planning a continuous Pharmaceutical manufacturing facility. Batch process manufacturing Traditionally, most human pharmaceuticals are manufactured in a step by step batch process with extensive tests between steps to ensure consistent quality and efficacy of the finished medicine. The manufacture of pharmaceuticals is a highly-regulated process with Government agencies inspecting and approving both the process and the facilities where medicines are manufactured. In 2016 the US Food and Drug Administration (FDA) allowed for the first time in its history a manufacturer to switch

The Role Of Flow Control In Hydrogen Production

Hydrogen has become a hot topic recently. Besides application in the traditional industry, we see more and more applications in the sustainable energy sector. Flow meters play an important role in Hydrogen Production, as reliable and precise flow measurements are essential to the process. For many years now, we have been supplying flow meters to HyGear in Arnhem (NL), which they use in their steam reforming units. Bronkhorst spoke with Ellart de Wit, CTO of HyGear, to find out more about this interesting market, the steam methane reforming units they develop, and the role that our flow meters play in

Mobile Calibration Setup For Flow Meters

How do you know for sure that the gas flow that you measure or set is right? The answer is quite simple: make sure that the flow instrument you are using to measure the gas flow gives the real value. Therefore, calibration (and adjusting) of the flow meter, at times, is necessary. What Is Calibration? Calibration is comparing the measurement value of a device under test – DUT – with a known (reference) quantity. Results of calibration are stored in a calibration certificate. In this particular case, Bronkhorst has developed a mobile calibration setup for a customer in the chemical

The Importance of Industrial Automation

Why Industrial Automation Is Needed The idea of automation has a history of making workers anxious. This is because when some people hear “automation” they think “layoffs”, but the truth is that industrial automation can make their jobs easier and increases productivity. The addition of automation to an existing manufacturing workforce increases 2% on average per year. Industrial Automation Tools Industrial Automation uses control systems such as computers, robots, and information technology. An example of this is our Horner OCS controllers which are used to control different types of processes and machinery. These control systems are used to perform tasks

Humidification of Fuel Cells

Inside the engine of your car, gasoline reacts directly with oxygen from the air to cause combustion which enables your car to drive. This is the conventional way. Chemical energy is converted into useful mechanical energy. An alternative for this is combustion in an indirect way: a more clean and promising manner using a fuel cell. Oxygen and fuel, such as hydrogen, are fed to each side of the fuel cell, to electromagnetically react inside the cell forming water. As a result, electrons flow through an external circuit powering an electric motor. The chemical energy from the fuel is converted
