Temperature monitoring for trace-heating applications

The new digital temperature controller DPC III (photo) is optimally matched to trace-heating applications. It monitors measuring circuits on breaks, interruptions and short circuits of the sensor as well as on under- and over-range in order to guarantee process safety.…

Measure mass or volumetric energy flow with this meter

The DIVA compact steam flowmeter is offered for general metering applications as well as fiscal metering, product costing and efficiency monitoring. With automatic compensation for changes in steam density, the unit provides 4 – 20-mA and pulsed outputs proportional to…

Flowmeters for very low flow

The mini Cori-Flow (photo) is the latest model in this firm’s series of compact Coriolis Mass Flow Meters/Controllers, and is designed for accurate measurement and control of very low flowrates. The full-scale capacity of the device has been extended from…

Communication blocks for field devices into control systems

The PCS7 to IEC 61850 TCP/IP communication blocks have enabled problem-free integration of IEC-61850-capable field devices into instrumentation and control systems based on Simatic PCS7 or S7. The plant operator thus has an integral automation and control solution that can…

This control module is coupled with digital mass flowmeters

The Compod programmable control module, coupled with Smart-Trak mass flowmeters (MFMs) and controllers (photo), greatly simplifies basic flow control installations and permits networking of multiple instruments using open-source Modbus RTU protocol. The unit can be configured for a variety of…

Condition monitoring & analysis integrated in automation system

This company has integrated machinery condition-analysis technology into the metsoDNA CR automation system. The application, called DNAmachineAssessor, enables maintenance staff to have first-hand access to machine vibration data and mechanical component condition analysis through the same user interface (photo), which…

These sensors do more than measure control variables

Hamilton The ARC concept (photo) is a new family of sensors for process control, which includes pH, dissolved oxygen and conductivity measurements. More than just sensors, the devices are complete solutions that include sensors, and direct standard interface to the…

Full-scale, PV-module durability testing is now possible

The XR360 is the latest technology for accelerated exposure testing of complete photovoltaic (PV) modules. The unit integrates recent developments in environmental-chamber and xenon solar-simulation technology. The XR360 is capable of testing modules up to 1.9 m X 1.4 m,…

This sensor monitors a wide range of conductivities

JUMO The tecLine LF-4P (photo) is a new cell with four-pin technology for measuring conductivity. The device fills the gap between two-electrode cells and inductive measurement technology, and makes it possible to cover a very wide measurement range from about…

Unbreakable switch technology finds application in keyboards

ITW ActiveTouch ITW ActiveMetal switches (photo) have been introduced to this firm’s ActiveTouch line of switch products. The patented pushbutton switch employs a low-voltage subminiature transducer, which generates megahertz frequency vibration to the pushbutton a thousand times per second and…
