MC Emerson Introduces Smart Valve Positioner 1 400

The PD Series enhances the current TopWorx portfolio of discrete valve controllers, providing 100% control over valve position and integrating communication via a 4-20 mA loop signal and HART protocols. Customers can extract valuable feedback through this intelligent communication and can monitor for trends that offer predictive maintenance insights to help prevent costly downtime.

To maximize reliability, the PD Series uses Hall effect contactless position detection. Two PNP alarms that can be configured throughout the full displacement range help improve plant productivity and safety in any process application. The construction of the PD series product line is also designed to withstand a variety of environmental conditions. The PD Series will launch initially with two models: The PD100 for general purpose applications and the PD200 for use in explosive atmospheres.

“Every facility, no matter its environment, needs to be sure it’s operating as safely and efficiently as possible,” said Paul Bristow, Global Product Manager at Emerson. “That’s why the PD Series was designed for trusted performance in demanding conditions in many different applications and industries.”

The compact and lightweight design of the PD Series delivers a high degree of versatility, allowing for quick and simple installation on rotary and linear actuators in many applications. The same solution can provide precision control on both single- and double-acting actuators. An LCD screen allows operators access to device status and optional magnetic key technology allows operators to set all functions of the device without removing the cover in the field. Low air consumption and fast response deliver efficient operations, providing a single solution for both standard and heavy-duty conditions.

The TopWorx PD Series is built to the same industry-leading standards as other proven TopWorx products, to deliver exceptional value and trusted performance for demanding applications. The PD Series is suitable for use in oil and gas, chemical, industrial energy, on-site utilities, power generation, pulp and paper, waste and wastewater and food and beverage applications.

MC PepperlFuchs Monitoring Condition of Plants w Vibration Sensors 3a 400

To enable long-term monitoring of vibrations, Pepperl+Fuchs recently launched a new portfolio of vibration sensors. You can find out what distinguishes these products in the following blog article. Using a wind turbine as an application example, we will also show you how you can use vibration and acceleration sensors in combination to keep an eye on both long-term and short-term changes in vibration.

The portfolio of vibration sensors

Pepperl+Fuchs has recently started offering a range of vibration sensors to perform reliable measurements of vibration velocity and acceleration in low or high frequency ranges. Compared to similar products, Pepperl+Fuchs’ vibration sensors have approvals up to SIL 2, a large measuring range of up to 128 mm/s, and automatic condition detection for ball bearings. Due to their robust housing and encapsulated electronics, the sensors impress with maintenance-free operation and a particularly long service life.

The three designs in the portfolio are available with different certifications and approvals. In this way, you can find the right vibration sensor for every application:

  • VIM3 series: The compact VIM3 series is suitable for applications up to SIL 1/PL c, and has output options for analog or IO-Link.
  • VIM6 series: The VIM6 series is approved for hazardous areas up to Zone 1/21. With an extended temperature operating range of -40°C … +125 °C, the sensors are ideal for high-temperature areas.
  • VIM8 series: Due to a particularly robust housing made of duplex steel, the vibration sensors of the VIM8 series are designed for use in offshore applications as well as in harsh and hazardous areas of Zone 1/21. Moreover, the sensors have an approval up to SIL 2/PL d.

 

Vibration sensors vs. acceleration sensors

Not only vibration sensors, but also acceleration sensors from Pepperl+Fuchs are used to measure changes in vibration: Both record the vibration acceleration in g. Nevertheless, the sensors differ in their technical operating principle and are therefore each suitable for different applications.
