Process Control

The explosionproof Hawkeye, with its stainless steel enclosure, is designed for service in harsh process environments. It features a solid state proximity sensor which is encased in a shock absorbent urethane potting material.

Determining problems and errors in the field just got easier with the new WIKA MH-3 pressure transmitter for mobile working machines. WIKA Instrument, LP captures the latest pressure sensor technology with the addition of the diagnostic function in the new MH-3 pressure transmitter.

In order to determine the Flow Rate represented as Q, we must define both the volume V and the point in time it is flowing past represented by t, or Q = V/t.  Additionally Flow rate and velocity are related by the equation Q = Av where A is the cross-sectional area of flow and v is its average velocity.

The Prism PI integrates an advanced position sensing system and integral pneumatic control for sanitary diaphragm and other linear applications. Compact and durable, the PI is suited for corrosive, heavy washdown and hazardous areas.

Selecting a valve with the correct flow characteristic (the relationship between valve opening and flow capacity) can be as important as the selection of the valve size.

Standard fluid line systems were for many years constructed from threaded pipe of assorted materials and were assembled with various standard pipe fitting shapes

At times it is necessary for a process engineer to choose between a pneumatically or electrically actuated valve for a system. There are advantages to both styles, and it is valuable to have data available to make the best choice

The choice of C3 technology and the hybrid variation is a logical decision based on the available choices for multiphase measurement.

Most pump problems are due to suction issues.
