The new PMI F90 inductive positioning system (photo) works with a patented multi-coil system. The absolute position of the actuator is precisely detected from the measuring signals of a single coil. In addition to sending the analog position signal, switch…
The LFV Series 8000 two-way inert solenoid valve (photo) is a miniature device whose small size ensures a more compact instrument footprint and means less fluid is needed, enabling closer valve spacing. These two-way, chemically inert, isolation-style valves provide an…
The RV Series of rotary variable differential transformer (RVDT) position sensors (photo) offer highly accurate angular displacement measurement of rotating elements, such as quarter-turn ball and butterfly valves, actuators, throttlers and tensioners. With a shaft that rotates a full 360…
The Jofra CTC-1205 compact temperature calibrator (photo) covers a temperature range of 100 to 1,205°C (212 to 2,201°F), with accuracy of±0.2°C (±0.36°F), and stability to±0.1°C (±0.18°F) for the total temperature range, along with improved calibration times when compared to its…
Waterflux 3070 (photo) is said to be the first water meter with integrated pressure and temperature sensors. The meter features simplified installation, integrated diagnostics, a long battery lifetime, remote communication options and low overall maintenance requirements. The updated Waterflux 3070…
This company has introduced two new portable calibration machines (photo) — the PCM, with a 2,000-lb f capacity, and the BCM, with a 10,000-lb f capacity. The PCM is capable of calibrating various types of load cells, hand-held force gages,…
Users of compressed air can take advantage of heat recovery to enhance their sustainability, improve energy efficiency and reduce system lifecycle costs Air compressors account for a considerable portion of industrial energy consumption, and facilities that employ large-scale air compression…
The pitfalls in cost estimating that cause project overruns have been well known for decades, yet they continue to plague the CPI When I first started writing this article, I set out to summarize the mechanics of project cost estimation.…
This methodology can be used not only for laminar flow, but also for the complete turbulent flow region In recent decades, the impact of energy costs on the transport of fluids has led to a significant reduction in fluid velocity…
The recommended velocities for fluids’ transportation must be updated periodically to obtain the optimum value of the pipe diameter in the current economic conditions To arrive at the optimum diameters for pipes, the heuristic criteria of recommended velocity has been…
