IEC TC65 Standards Work

IEC Webstore

The international standards for industrial-process measurement, control and automation are developed through IEC TC65. As stated on the IEC web site, the standards developed by TC65 address systems and elements used for industrial-process measurement and control concerning continuous and batch processes. These standards address equipment and systems operating with electrical, pneumatic, hydraulic, mechanical or other …

WirelessHART – Monitoring and Control of On-Off Valves


A number of WirelessHART devices have been introduced over the last few years to monitor the status of on/off valves. For example, the TopWorx 4310 WirelessHART Valve Position Monitor can be used detect linear and rotary movement using non-contact technology with limit switch feedback. Such devices provide a low cost way to monitor the position …

WirelessHART – Level Switch

2160 WirelessHART Transmitter

In many tank level control applications, a level switch is installed and used as an interlock to help prevent overfilling the tank. For example, in many existing installations you may find a vibrating fork liquid level switch wired as an input to the control system. However, today it is possible to reduce the cost of installing a …

WirelessHART – Discrete Measurement

702 Transmitter

Many manufacturers initially introduced WirelessHART field devices that were designed to support continuous process measurements such pressure, flow, temperature, and level. Also, WirelessHART transmitters are now available for analytical measurements such as pH. Recently you may have noticed that some manufacturers have introduced WirelessHART field devices for discrete measurement. For example, Rosemount has released the …

Using Wireless Measurements In Control Applications

Using Wireless Measurements in Control

Wireless transmitters may be preferred in applications where new measurements are required since the cost may be lower than that associated with installing wired transmitters. However, there is a significant differences in the frequency and manner in which a new measurement value is updated by a wired transmitter vs. a wireless transmitter. Such differences must …
