Expansions and contractions in the process automation industry
Microsoft teams with OPC Foundation to support IIoT; Emerson updates SCADA system, RTUs.
Microsoft Corp. is working with the OPC Foundation to enable almost any IIoT scenario using interoperability between the millions of OPC UA-compliant applications and equipment. Microsoft will enable IIoT users to connect manufacturing equipment and software with extended support of OPC UA's open-source software stack. Microsoft’s extended support for OPC UA spans its IoT offerings from local connectivity with Windows devices to cloud connectivity via Microsoft Azure. Integration with Azure IoT allows customers to easily send OPC UA data to the Azure cloud, as well as command and control OPC UA devices remotely from the Azure cloud.

Liquid radar level moves up to 80 GHz
Narrower beams, smaller antennae and higher sensitivity handle compact, cluttered or non-conductive applications.
Noncontact radar level technology is widely used, offering accuracy to 2 mm, range approaching 200 meters, and tolerance of extreme pressures and temperatures with high stability, no moving parts and little maintenance. Steady improvements in signal processing that allow it to accommodate a broad range of vessels and process materials, along with reduced power consumption (including two-wire versions that operate on 4-20 mA) and lower costs have made it the first choice of many instrument specifiers for liquid level.
But conventional noncontact radar is restricted to 26 GHz, which leads to compromises in antenna size and beam angle that limit its ability to accommodate foam, buildup and spurious reflections from mounting fittings, tank…

How to troubleshoot and calibrate 4-20 mA
Taming temperature and pressure
Béla Lipták on safety: Oil and Gas
Best practices for troubleshooting analog circuits to the PLC.
A Control Design reader writes: We have several temperature, pressure and flow sensors on a new medical-device cleaning skid that we are developing. These instruments are connected to a PLC as 4-20 mA inputs, and there is also a 4-20 mA output used to control a pump motor speed. A recent failure of a flow sensor brought the process skid instrumentation to my company's quality manager's attention. He asked how we know that the temperatures, pressure and flow are accurate, and how do we know that we are cleaning properly.
I've been tasked to write a procedure for troubleshooting, calibrating and testing the 4-20 mA instruments on the skid. I can probably stumble through this, but what are some best practices for troubleshooting the analog…

Meggitt offers HART-enabled vibration sensors
Meggitt's PCH420V vibration sensor has a programmable transmitter that allows vibration data to be accessed by HART enabled process controllers.
Meggitt's PCH420V is the first HART®-enabled piezo-electric vibration sensor enabling continuous online monitoring of balance-of-plant assets with a digital connection to PLC or DCS systems for local analysis of multiple vibration bands. They are capable of installation in multi-drop configurations and reduce wiring requirements. HART functionality enables the user to specify vibration frequency bands, detector types and full-scale measurement ranges—effectively enabling field-configuration for specific monitoring requirements.
PCH420 sensors are powered by the network for continuous coverage, unlike wireless solutions only offering snapshots of asset performance and employing batteries that require frequent replacement. Utilizing PCH…
