Emerson Introduces Digital Valve Controller with Stainless Steel Housing for Corrosive Environments

Emerson DVC6200 stainlesssteelEmerson’s Fisher FIELDVUE DVC6200 digital valve controller family gains added capability with its all stainless steel housing that withstands the corrosive atmospheres often experienced in chemical plants, pulp and paper mills, as well as near-shore and offshore oil and gas installations.

All DVC6200 series instruments utilize a patented linkage-less, non-contact feedback design to detect valve position. This valve positioning technology eliminates any travel feedback issues caused by corrosion, high cycle or high vibration applications.

In addition to external protection, corrosion resistance is found within the stainless steel housing with the digital controller’s fully encapsulated printed wiring boards. Internal component protection is further enhanced by a separate, weather-tight field wiring terminal box that isolates the field wiring connection from other areas of the instrument.

Emerson Integrates Valve Position Transmitter and HART 7 Communications Within its Digital Valve Controller

Emerson’s Fisher FIELDVUE DVC6200 digital valve controller series now incorporates a 4-20mA position transmitter that can also be configured as a discrete switch. Having the valve position transmitter function integrated within the valve controller means that the expense, bracketry, and maintenance requirements of an add-on, accessory transmitter are eliminated.

Spirax Sarco SP500 Positioner with HART Communications

Spirax Sarco SP500 Positioner with HART CommunicationsSpirax Sarco is helping instrumentation users reduce their energy consumption with their ultra-efficient SP500 positioner with HART communications. This positioner consumes approximately 1% of the air of a traditional electropneumatic positioner and has class-leading low impedance helping to save on controller power. The SP500 digital positioner supports HART communication protocol. This protocol comprises of a digital data transfer and communication over existing 4-20mA wiring, requiring no additional power supply or wiring to the positioner.

Emerson Introduces the Fisher FIELDVUE DVC6200 SIS Digital Valve Controller

Emerson DVC6200 SISEmerson’s new FIELDVUE DVC6200 SIS digital valve controller responds to safety demands, and features partial stroke and position monitoring capabilities for the final control element in a safety instrumented system (SIS). Intelligent automatic partial stroke valve testing provides improved safety and reliability versus traditional pneumatic and jammer partial stroke methods.

Meeting plant safety and reliability targets is easier using the DVC6200 SIS, which combines the field-proven linkage-less, non-contact feedback design of the DVC6200 and DVC2000 platforms with the safety demand and automatic partial stroke testing capability of the DVC6000 SIS. The DVC6200 SIS has been evaluated to the latest version of IEC 61508 (2010) and is certified as a SIL 3 capable device for either 4 or 20mA and 0 or 24Vdc power settings.
