Speedy delivery of calibration data
Calibration is a complex procedure that takes time, and time is money. Here's how some facilities are saving both and also getting better data
Do you know what you're looking at? Are you really seeing what you think you're seeing? How can you be sure? How fast can you do it?
These are some of the unsettling questions that characterize the need for calibration in process control. The reason…

Pressure transmitters meet new challenges
Pressure transmitters and their related components are rising to meet new challenges.
Dp without lines and tubes
Deltabar FMD71 level transmitter uses two pressure sensor modules—hydrostatic and head pressure—connected electronically to one transmitter. Using a Ceraphire ceramic sensor, the transmitter calculates differential pressure (DP) from both sensors, and transmits level, volume or mass via 4-20 mA with HART, eliminating DP measurement problems caused by impulse lines or capillaries.

Quickly Test Load Cell Systems
BLH Nobel Introduced a System That Quickly and Easily Checks Weighing Systems for Wiring and Mechanical Faults
Load cell weighing systems solve some of the knottiest problems in batch and level control by directly measuring masses of solids and liquids as they're accumulated, dispensed or conveyed. But the load cells must be installed and wired properly, and the load structure must be engineered and constructed correctly to distribute the measured load as axial forces on the cells. What appear on the surface to be simple wiring and construction tasks have caused more than a few problems during commissioning and maintenance due to miswired or poorly made connections, distorted or binding structures, incorrectly installed load cells or rigid connections to adjacent equipment.
Such problems often are not found until a new installation is being…
