What is a Resistance Temperature Detector (RTD)?
. The accuracy of an OMEGA standard RTDs is shown in the table on the right. RTDs are also relatively immune to electrical noise and therefore well suited for temperature measurement in industrial environments, especially around motors, generators and other high voltage equipment. Accuracy for Standard OMEGA

Introduction to Infrared Thermometers
are required because of contamination or hazardous reasons (such as high voltage), where distances are too great, or where the temperatures to be measured are too high for thermocouples or other contact sensors. What should I consider about my application when selecting an infrared thermometer

Thermal Spray Gas Flow Contol
. To provide accurate and stable flow control the HFC 303 Mass Flow Controller is recommended for this application due to its fast response (<2 seconds), high accuracy (better than 1%) and insensitivity to ambient temperature and pressure. The HFC 303 can be factory calibrated for any of the fuel

The Advantages of Mass Flow Meters & Controllers in Fuel Cell Test Stands (.pdf)
quickly much. like a car accelerator to provide a true test of the desired performance. In addition, the. MFCs must have a broad turndown to mimic low and high fuel consumption rates. Many. fuel cell test stands use MFCs that do not have the performance capabilities to. adequately test fuel

Principle of Mass Flow Instruments: Principle of Mass Flow Sensor
of mass flow controller. In the mass flow controller shown inFigure 5, the opening of the flow control valve is controlled by a high-velocity, high-resolution piezo or solenoid actuator based on the comparison between the external flow setting signal and the flow signal output from the sensor. This system

Important Considerations to Performance of Sodium Hypochlorite Wastewater Treatment Piping Systems
to the breaking of weak ionic bonds with its base molecule, Sodium Hydroxide. Piping material, valve selection, seal materials, pressure relief, and stagnation control, are a few design, safety, and operational measures to consider when designing NaOCl systems. Sodium Hypochlorite carries a relatively high pH

Improve Bioreactor Performance by Using Mass Flow Controllers
. The rotameter PDL had been using was not adequate for measuring the low flow rates needed to prevent excessive foaming. "We now have a high degree of confidence in our flow rate," says Sauer. "When we were using rotameters to control our flow rate at the lower edge, we experienced a substantial

Liquid Films Falling Over Horizontal Tube Banks: Deviations from Idealized Flow Patterns and Implications for Heat and Mass Transfer (.pdf)
Liquid films falling over banks of internally cooled horizontal tubes are often used to absorb mass from a surrounding vapor. This arrangement is particularly suitable for absorption processes where the vapor has a high heat of absorption and where high transfer rates and low pressure drops
