Surface Heating for Analytical and Scientific Instrumentation

analytical and scientific
applications. (BriskHeat
In many research & development and laboratory applications, surface heat is required to successfully conduct experiments and tests. The heat may be required for a number of reasons:
  • Temperature Compensation - Varying results due to temperature fluctuation are eliminated when the temperature is constant over several repetitions or tests.
  • Vacuum Bake-out - Heat helps release moisture and impurities/particulates in a closed system to allow the test results to be more accurate and consistent.
  • Temperature Elevation - A higher temperature may be required to generate the desired results.
The document below, courtesy of BriskHeat, provides electric heating solutions for various laboratory applications where analytical and scientific apparatus require heat. You can also  download a PDF of "Surface Heating for Analytical and Scientific Instrumentation" here.

Features of Magnetic Level Gauges (Magnetic Level Indicators)

Magnetic level gauges, also known as magnetic level indicators, are routinely used to provide a display of liquid level in tanks and other vessels. Their popularity stems from their high visibility from distances and non-invasive design which reduces the possibility of leak points and the risks of fugitive emissions.



"Mag Gauge" construction is fairly simple. A magnetic float, designed for the specific gravity of the material being measured, rides inside a vertical pipe on top of the process media. A gauge with magnetically coupled visual indicator is fastened to the pipe. As the media inside the pipe rises and falls, the visual indicator moves in the same fashion.



Magnetic level gauges are often employed in tandem with magnetostrictive, guided wave radar, or other measurement means to provide a reliable local display of liquid level, as well as an electrical signal that can be transmitted to recording instrumentation or controllers.


The features of magnetic level gauges include:
  • Low maintenance. 
  • Wide operating temperature and pressure range.
  • Visual tank level indication. 
  • Continuous level measurement.
  • Easier to read from greater distance than glass sight gauges. 
  • Can be applied to wide fluid level ranges with a single instrument. 
  • Break resistant, sturdy.
  • Wide range of construction materials available.
  • External mounting of ancillary indicators, switches, and transmitters with isolation from process media. 
  • No electric power required for operation.

There are a number of options available so you can customize the level indicator for each specific application.  The best way to proceed is to combine your process knowledge with that of a product specialist.  Collectively, you'll be able to achieve an effective solution to your application challenge.

Process Refractometers for Food and Pharmaceutical Use

There are many industrial applications for process refractometers; particularly useful in the food and pharmaceutical industries, where there is a need for solids content measurement. Process refractometers are used to optimize production processes, ensure consistency and purity, and in managing quality control. Process refractometers and inline process refractometers, are types of refractometers designed for the continuous measurement of a fluid flowing through a pipe or inside a tank. They provide analysis to quickly, dependably, and to accurately identify a sample to determine its concentration and purity levels. By measuring the refractive index and temperature of flowing liquids, refractometers can then apply a mathematical function to determine the precise concentration of dissolved solids.

In commercial food applications such as jam or jelly production or the processing of soft drinks or wine, refractometers are used to measure degrees Brix. Bix is a graduated scale, used on a hydrometer, that indicates the weight of sugar per volume of solution at a given temperature. The Brix scale relates refractive index to sugar concentration, and is a method of maintaining consistency. For example, process refractometers are used for the concentration process of fruit juices. The concentration process is normally achieved by removing water through evaporation, and by measuring Brix, the evaporation process can be controlled and related to the desired juice concentration.

Process refractometers are also used in pharmaceutical processing where there is the need to monitor and control concentration levels during supersaturation, a critical process in crystallization. Crystallization is a critical element in the purification of solids in pharmaceutical production. The process refractometer guarantees precise monitoring and a high degree of measurement accuracy and reliability, towards the production of a pure product.

Safeguarding CO2 Measurements: How Intelligent and Automatic Sensor Protection Increases Performance

Instrumentation uptime and accurate measurement values are core requirements of in-line dissolved CO2 measurement systems used in carbonated soft drink facilities, breweries and boutique beverage producers. The stability and protection of the wetted sensor along with the instrument air supply are core requirements to ensure reliable measurement data. Instrument damage, incorrect CO2 readings, and poor quality can result from an unknown or undetected failure of the sensor.

The following paper, courtesy of Mettler Toledo Ingold explains how intelligent and automatic sensor protection increases reliability, quality and performance.
