Today’s Session u u u 3 Solid State vs. Electromechanical Product Line Overview Product Feature Overview Design Target Markets Common Application Example

Solid State vs. Electromechanical u. Market n n outlook (worldwide): Unit shipment declines of electromechanical through 2011 High single-digit growth rates for solid state switches Sensor Type 2006 2011 Share Change Diaphragm 68. 8 67 -1. 8 Bellows 10. 8 10. 7 -0. 1 Piston 10. 1 9. 9 -0. 2 Bourdon Tube 1. 9 -0 Solid State 8. 4 10. 5 +2. 1 100% Source: 2006 VDC Research Group 4

Solid State vs. Electromechanical 5 Solid State Electromechanical 100 M cycle switch life 1 M cycle switch life No set point drift (No moving parts) Set point drift (wear of moving parts) Fully adjustable deadband Fixed or narrow deadband Continual self-monitoring to detect errors No diagnostics Smaller size due to solid state circuitry Larger size to accommodate moving parts Visual indication via digital readout No visual indication Good for high cycle applications (up to 100 times per second) Slow response

Product Line Overview u 3 discrete components combined into one compact device n n Gauge, Switch, Transducer Less than the cost of all three units combined Easier and cheaper to maintain Can change parameters without shutting down manufacturing line + 6 + = UDS 7

Product Line Overview u UDS 7/SW 2000 – Electronic pressure switch n u UTS 7/TS 2000 – Electronic temperature switch n u Dual switch outputs and/or 1 analog output UDS 3/UAS 3/UQS 7 – Multiple switch outputs with analog output n 7 Dual switch outputs and/or 1 analog output Control pressure, temperature, level, flow

Product Feature Overview u Electronic Pressure & Temperature Switches n n n n 8 Digital display 0. 50% accuracy Multiple switch points Adjustable dead band Self-diagnostics Compact size UL/CSA Approvals Can replace multiple electromechanical switches

Product Feature Overview u Digital Display n n n u u Easily configured through keypad Switch points can be set to alarm codes n u In the event of a problem, switches can be set to shut off equipment Continuous error monitoring n n 9 Shows actual system pressure or temp, status of switch points, and any alarm or error conditions Can alert users to potential problems Can assist in finding out “what went wrong” Constantly monitors up to 10 different parameters Lets you know switch is working

UAS 3 Digital Display Scalable Bar Graph Display in PSI, Bar, C°, F°, k. Pa Trend Indication Switch Point Indication Control Menu 10

Product Feature Overview u u u Self-diagnostics on power-up Tamper proof Operation Modes n n n u u u 11 Standard mode Window mode Error output mode (switches actuate when an error is encountered) Can set a delay time up to 9. 9 seconds Can be set either Normally Open (NO) or Normally Closed (NC) Easily adjustable and programmable in the field

Switch Setting – Standard Mode u Standard mode n 12 Switches have menu settable on and off points, allowing them to be actuated on increasing or decreasing pressure

Switch Setting – Window Mode u Window mode n 13 Switches set to actuate when pressure falls either within or outside a user-set “window”

Window Mode - Example u Machine tool – Clamp Control n n n 14 If pressure is too low – workpiece too loose If pressure is too high – damage the workpiece The Window function offers a controlled “Pressure Window”

Product Design u Piezoresistive Pressure Sensor n Essentially the same operating principle as a transducer: Diffused Silicon Sensor n Wheatstone Bridge n n 15 Change in pressure causes change in resistance, resulting in a proportional output signal Ideal for low and medium pressures in absolute and gauge ranges Provides high accuracy in a wide temperature range

Target Markets u 16 Pressure Control for: n Steel Mill Equipment n Hydraulic Power Packs n Gas Mixers n Automotive OEM Applications n Hydraulic Presses n Pumps and Compressors n Machine Tools (CNC, welding machine) n Wind Turbines n Plastics Injection Molding n Food/Beverage n Pharmaceutical n Pulp/Paper

Application u Pump control system with dual pumps may use: n n n u UDS 3 can replace all these n n 17 Two dual switch electromechanical pressure switches 4 -20 m. A transmitter Local Gauge Savings in time, money Improved accuracy Longer life Reduce installed cost

Summary u Solid State Switches n n n 18 Long life (100 m cycles) Good for rapid cycle applications Can replace multiple electromechanical switches Can replace several components (switch, gauge, transducer) Offer visual feedback Are programmable
