Process transmitters Electronic pressure measurement IwikaII ^ Part of your business

Versatile in application Process transmitters are suitable for many industrial measuring requirements in the widest variety of applications. They monitor pumps, detect the level in The measured value can be read on site as well as being transmitted to a process control system, a controller or a terminal. The data transmission is achieved using an analogue 4 ... 20 mA signal or via a bus protocol. With the HART®, PROFIBUS® PA or FOUNDATION™ Fieldbus bus systems, there is the possibility to transmit further information from the process and/or measuring instrument, in addition to the primary...

Communication with process transmitters Fieldbus systems in process control technology Process Control Systems (PCS) are observing units that fully monitor, manage and control industrial plants (for example). All parameters and measured data related to the process are transmitted to a central point and evaluated according to a defined algorithm. A purely analogue output signal only enables the communication from the measuring instrument for control. With process transmitters with fieldbus interfaces, further possibilities are offered. The digital bus signal, or also the HART® protocol,...

DTMs (Device Type Managers) Alongside the primary value (PV), the digital bus instruments also enable further values to be passed on to the instruments that relate to the same data loop. This therefore offers the possibility, for example, to react to a rising temperature value in a sensor. Likewise, the instrument can output already calculated values such as level in units of length and volume in litres (for example). This requires a continuous input of process data and the possibility to be able to change the instrument parameters easily. Such possibilities are offered by DTMs (Device Type...
