This gas-sorption analyzer has new temperature capabilities
The Cryocooler is a sample-holding accessory to this company’s gas-sorption analyzer, which is used to measure surface area and pore size of industrially useful porous materials and powders, and to investigate sorption capacity of state-of-the-art materials, such as carbons, zeolites,…
Thermowell Installation
Temperature is among the most critical measurements in the chemical process industries (CPI) for operating safe and efficient processes. Because even a small error in temperature can lead to expensive consequences, accurate and reliable monitoring of temperature is required. Thermowells…
Motors: Taming the CPI’s Energy Beast
Whether for pumping, mixing, compression or ventilation, motors are used everywhere in the chemical process industries (CPI). Unfortunately, they are notoriously energy intensive, accounting for about 65% of the electrical consumption of a chemical production site. However, with the world,…
A compact flowmeter that has no moving parts
Mag-View is a compact, high-quality, yet economical, device for measuring liquid flowrates in applications where flow sensors with moving parts cannot be applied. Its interference-free operation, combined with a long lifecycle and independence from the inlet and outlet pipework makes…
Accurate RH & temperature measurement in harsh environments
To best meet specific application needs, the DT722 relative humidity (RH) and temperature transmitter is available in digital (DT722) and analog (DT722-X18) models. The digital version gives high performance measurement with “excellent” RH accuracy and delivers reliable, consistent and accurate…
Three new digital displays for your measured values
The Afriso DA 10, 12 and 14 digital display units are suitable for displaying measured values and evaluating and controlling standard signals (4–20 mA, 0–1 and 0–10 V) from electronic transducers, especially in level applications. The connected transducer is supplied…
Increasing the sensitivity of trace-element analysis
By using electrothermal vaporization (ETV) for sample introduction, this company has greatly improved the sensitivity of its Arcos ICP-OES spectrometer for material-analysis applications. Trials verify that detection limits can be improved by an order of magnitude. At much lower cost,…
Compact remote I/Os save space and the cost per channel
Four-channel analog I/O modules can be placed in a 16-mm-wide enclosure due to a new energy-saving electrical design. This results in a space savings of 50% compared to the predecessor model, says the company. The new design reduces the cost…
Sizing Calculations for Pressure-Relief Valves
Pressure-relief valves are widely and effectively used in situations where the pressure in a process vessel rises to above the vessel’s design-pressure rating. Proper relief-valve sizing is critical to plant and process safety to permit fluids sufficient flow area to…
A temperature sensor designed for pipe surfaces
The TF44 sensor is designed for measuring the temperature on pipe surfaces. The small design of the protective sleeve enables optimized mounting of the sensors and the insulation above them, even on pipelines with a small nominal width. The thermowell…
