With Smartsens, Krohne has unveiled the first family of analytical sensors that eliminates the need for external transmitters, thus allowing users to rule out some of the typical problems that affect analytical measurement. A revolution in analytical measurement, Krohne states — but read for yourself ...
The safety and reliability of components used are among the basic requirements of the process industry. Strict requirements and recommendations for the design and construction of the devices employed therefore exist for many areas and applications, including for the analytical measurement tools used, which differ considerably in terms of handling from the tools leveraged to quantify volumetric flow rates, fill levels, pressure, and temperature. These differences also have an effect on safety and reliability and represent potential sources of error. A new generation of analytical measurement tools helps to prevent some of these errors from occurring in the future.
Safe and Reliable Sensor Performance
The requirements placed on the safety and reliability of the measurement tools used have different origins and result from implementing standards, guidelines, and recommendations from committees and work groups and from those referenced in test sample and model designation certificates as well as certifications, for example. The overarching objective is to identify any and all possible sources of error in conjunction with using the devices. Although analytical measurement tools are not excluded, their reputation for being complex and expensive to handle precedes them in particular.
Whether it is the handling of sensors, wiring, configuring the measurement point, or calibration, the topic of analysis is always viewed differently as compared to the measurement tools employed to quantify volumetric flow rates, fill levels, pressure, and temperature. All of this changes with the introduction of Smartsens. This new family of analytical sensors is far removed from the systems currently available on the market and was developed specifically with respect to safety and reliability.
No More External Transmitters
Smartsens sensors are characterized in particular by the fact that they no longer require an external transmitter, since it is already integrated in the plug-head connector of the sensor. The 2-wire sensors transmit a 4 to 20 mA signal with Hart 7 communication for direct connection to the control system from the plug-head connector. What initially seems quite simple is actually a revolution in analytical measurement upon closer examination. What benefits does this design have for the safety and reliability of a measurement point?
