Technology Roadmap TODAY (Gen 2) NeSSI™ Roadmap End of 2007 (full IS and Control Solutions available) TODAY (Gen 2) End of 2006 ( “Gen 1.5”, analog and mechanical) Initiative “Gen 1.0”, started 1999 NeSSI™ is a trademark of the Center for Process Analytical Chemistry, University of Washington

Status CIRCOR Tech built working Siemens I2C devices and delivered to the field in early 2007 CIRCOR participated in the CAN in Automation (CiA103 working group to help finalize draft document in early 2007 CIRCOR moved forward with several iterations of IS and non-incendive technology

Component Solutions

Multivariable Devices Multi-Variable Flow Meter Upstream and Downstream Pressures Flow rate Fluid Temperature Closed-loop Control All Intrinsically Safe (IS) except for Modbus version Contains device description in memory Digitally re-scale of ranges Field rescale of orifice pack Integrated pressure relief valve 1.5” x 3” x 4” (WxLxH) size IP65, NEMA 4X package

Flow Meter Features Different connectors and status indicating LED’s IP rated SS enclosure Digital Address ID IS Circuitry in mother daughter board arrangement for different sensor interfaces and different connector types New multi-variable pressure, differential pressure, and temperature combo sensor (co-developed with Ametek using their MEMS Technology) Anti-clogging flow restriction with integral relief valve

Flow Meter Three bus versions are (or will be) available IS CAN Bus Siemens I2C Maxum GC bus Modbus/RS485 Principle operates on measuring DP-P-T across a flow restriction, using new multi-variable MEMS sensing technology Focusing on repeatability and reliability applications over pure accuracy applications Closed-loop version will be available with a “combi-valve” using proportional air signal for IS considerations

Flow Meter COO

Future Flow Meter Using the same sensor and circuitry, we can now use a particle filter as the flow restriction element. With intelligent sub-routines, the device can self-calibrate. The device can monitor the status of the filter over time and tell the operator or a computer when the filter is clogged to a critical point.

Valve Solutions Ultra Low powered solenoid valve manifolds Intrinsically safe Multiples of six per bus node to save on cabling cost Up to 85 deg C Can go inside the sample cabinet IP65 protection Less 0.1watts per valve (maximize power budget)

System Solutions

Bus Descriptions Modbus Devices: Based on an RS-485 physical layer Communication protocol invented by Modicon (PLC manufacturer) Widely used in automation products and integrated with almost all PLCs Typically used in Class 1, Div2 (zone 2) applications but can be used in Class 1 Div 1 with IS certified devices and IS isolator repeater/barriers Limited to 1-2 devices per Isolator/Repeater due to power consumption (i.e. 24V technology) Siemens Maxum I2C: Based on proprietary physical layer Used inside of Siemens Applied Automation Inc. (SAAI) process GC for years Robust and simple, Plug-and-Play Can only be used with Siemens hardware (configured to Siemens specifications) CAN bus Devices: based on CiA103 physical layer standard CT76 iCAN™: CIRCOR Application Layer Protocol based on “Modbus emulation” and IEEE1451.1 Electronic Data Sheet description using CiA103 physical layer and core Bosch CAN 2.0 data link layer (ISO 11889-1) CANopen: A open standard application layer (EN 50325-4, CiA DS301) (more device resources needed, but available today)
