High-quality components are essential for safe and reliable production processes. They are a precondition for highly efficient processes, helping to avoid danger to people, environment and property. Rigorous testing of the instruments used, by national and international authorised bodies, results in reliability and stable workflows. WIKA instruments offer a wide range of approvals and certificates, worldwide. APPROVED The safety integrity level (SIL) of a component is certified through a manufacturer's declaration on the basis of an FMEDA (failure modes, effects and diagnostic analysis)....

Instrument requirements Fieldbus systems Bus technology The general trend towards using digital bus systems instead of the conventional field instruments with an analogue output signal is also being seen in power engineering. Advantages: ■■ Higher accuracy ■■ Reduced wiring requirements ■■ Extended diagnostics of field instruments ■■ Improved process monitoring Standard output signals Based on the variety of output signals available our measuring instruments can be easily integrated into any plant concept. Among others, the following standard output signals are available: ■■ Analogue (e.g....

Wake frequency calculation Wake frequency calculations are carried out as a mathematical confirmation of the strength for thermometer thermowells with respect to the static and dynamic loads under the process conditions. In the last years they have gained more and more importance. While in the past, for many years, experience defined the design of thermowells with the end user, today the dimensions of the thermowell are matched to the process through computation. The most prevalent basis for this calculation, worldwide, is ASME PTC 19.3. Through the wake frequency calculation, a greater...

Instrument requirements Increased safety with high process loads Calculations for establishing the stability of thermowells make it possible to minimise or eliminate the possibility of damage to the thermowells even before the plants where they are used are commissioned. The calculations can be made in accordance with ASME PTC 19.3 or Dittrich/Klotter. The following process parameters are required to complete the calculations: ■■ Flow rate in m/s ■■ Medium density in kg/m³ ■■ Temperature in °C ■■ Pressure in bar Independently of the thermowells’ method of manufacture, the results of the...

Pressure The WIKA programme is divided into a number of product lines and is thus suited to the widest range of applications. In addition, many instruments can be combined with each other or can be extended, for example with diaphragm seals, capillaries or thermowells. Transmit WIKA offers a complete range of electronic pressure measuring instruments: Pressure sensors, pressure gauges with output signal and process transmitters for the measurement of over-, absolute and differential pressure. The different pressure measuring instruments are used for the monitoring of overpressure, in level...

Product portfolio Instrumentation valves and accessories Very often, pressure measuring instruments are installed in combination with valves to enable an easy separation from the process for recalibration or replacement. WIKA offers a wide range of valves, valve manifolds and monoflanges, which can perform shut-off, venting and compensating functions. A variety of sizes and connection types, such as NPT, G and IEC connection, and also mounting brackets for wall or pipe mounting are available. Instrumentation valves Protective devices

Product portfolio Temperature Within the power plant industry, temperature plays an important role and is used in almost all circuits. One will find this measurement technology in 2 out of 3 measurements, among others, for boiler or flue gas plant protection; however, temperature sensors is also installed in many control circuits. For all of these demanding applications, WIKA has the right sensor and transmitter. Transmit Our range of products includes thermocouples, resistance thermometers as well as analogue and digital temperature transmitters for all applications in power plants. Switch...
