Siemens has further developed its TDL technology with the Sitrans SL diode laser gas analyser featuring an inline reference cell filled with a non-interfering reference gas allowing for a fast and non-contact measurement of gas concentrations in process or flue gases.
ABB has enhanced its 364 series of differential and gauge pressure transmitters with the addition of all welded direct and remote-mounted diaphragm seals. The 364 series is designed to suit a wide range of industries, including those with aggressive or hazardous environments where performance needs to be optimised, such as those in chemicals or offshore oil and gas production.
The Flexar is a continuous level measurement sensor used for monitoring the amount of material within tanks, silos, bins and many other types of vessels. It is used to measure the level of powders, granular and liquid materials and is a universal technology for use in a wide range of applications and industries.
The Sitrans LVL100 and LVL200 vibratory switches are suitable for high and low detection of all liquid media, independent of mounting position. The compact, user-friendly switches measure reliably in dynamic conditions, such as variations in the dielectric permittivity of a medium or the formation of vapour or bubbles.
FCI’s ST51 flowmeter is designed to measure digester gas, biogas and other methane-composition biofuel gases as well as natural gas. FCI precision calibrates all ST51 flowmeters in its NIST-traceable flow lab to match the gas composition of the user’s digester system and under the specific flow conditions of the user’s digester system.
The UltraStable US5100 pressure transducer from Measurement Specialties features a total error band of just 0.75%. It exceeds the latest heavy industrial CE requirements — including surge protection — and is voltage surge protected in both positive and reverse polarity.
The type MIK flowmeters offer four measuring tube widths from G 1/4 AG to G 1 AG and thus four measuring ranges from 0.5-4 to 10-100 L/min. These devices use the magnetic-inductive principle of measurement and are suitable for many applications like the monitoring of additives or cooling agents, consumption measurement or charging.
The Department of Mining Safety and Health has issued a product recall of Industrial Scientific’s 4CF carbon monoxide sensors, after finding some makes could suddenly stop detecting the gas.
Ensuring measurement accuracy often means going beyond reading raw specifications in a data sheet. Understanding an application in the context of its electrical environment is also important for securing success, particularly in a noisy or industrial setting. Ground loops, high common-mode voltages and electromagnetic radiation are all prevalent examples of noise that can adversely affect a signal.
