Pressure transmitters for remote commissioning of functional safety

Tuesday, July 3rd, 2018 von admin

Siemens presented Sitrans P320/420, the first pressure transmitter on the market to feature remote safety handling reducing commissioning time in applications requiring functional safety.

Via Simatic Process Device Manager (PDM) the safety integrity level (SIL) devices will be commissioned: rather than manually attending to each individual device across the facility, operators can commission transmitters from the control room. This next generation of pressure transmitters was developed according to IEC 61508 standard for the use in SIL 2/3.

Grundfos: Direct Sensors – the sense organs of the pump

grundfos DirectYou can only change what is accessible by measurement – whoever wants to control a process flow of a pump needs reliable current data on the one hand, and on the other, possible intelligent linking and interpretation of this data: Sensors deliver data, microchips have stored software to interpret this and actuators implement the commands. To also offer technical benchmarks, the pump manufacturer Grundfos maintains well-equipped own research and development departments, finance and personnel dealing with motors, frequency converters, sensors, microchips and their programming.

The ‘Direct Sensor’ development is a micro-mechanical semiconductor sensor (MEMS, Micro-Electro-Mechanical System), which is produced in its own wafer fabrication facility of purity grade 10.
