Electronic Pressure and Temperature Switches: Session #2 • UDS 7 • SW 2000

Today’s Session – UDS 7 & SW 2000 u u 2 Product Features Design Applications Benefits – How to Sell it

Product Features – UDS 7 u u u u 3 Two switch outputs and 1 analog output (4 -20 m. A; 0 -10 VDC output option available) 4 -digit LED dot matrix display Pressure ranges: 0 -150 to 9000 psig; 0 -15 to 0 -150 absolute Stainless steel housing 4 Pin M 12 electrical mating connector Process connections: ¼” NPT, 7/16”, G ¼ (Rotatable option w/G ¼) Shock and vibration tested; (50 G shock, 10 G vibration) UL/CSA, CE approvals

Product Features – SW 2000 u u u u u 4 Lower cost “OEM” version of UDS 7 Two switch outputs or 1 switch and 1 analog output (4 -20 m. A) Lower cost housing – die cast aluminum 3 -digit, 7 -segment LED display (lower cost) Pressure ranges: 0 -150 to 9000 psig; 0 -15 to 0 -150 absolute 4 Pin M 12 electrical mating connector Shock and vibration tested; (50 G shock, 10 G vibration) Process connections: ¼” NPT, 7/16”, G ¼ UL/CSA approvals

Product Features u u u 5 High Accuracy (0. 5%) Long Life (100 m cycles) Multiple Switch Points Visual Feedback (Digital Display & LEDs) Compact Size Programmability Analog Output Time Delay up to 9. 99 seconds Adjustable Deadband Tamper Proof Replace 3 components with one

Product Design u Piezoresistive Pressure Sensor n Essentially the same operating principle as a transducer: Diffused Silicon Sensor n Wheatstone Bridge n n 7 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

Application – Wind Turbines u Wind Turbine HPU (Hydraulic Power Unit) n n u u 8 SW 2000 is used as pressure control and readout for pressure associated with brake and pitch control of blade. Accuracy is required. Typical HPU is used for supplying hydraulic oil for brake, pitch, yaw and cooling applications Aftermarket replacement of competitor We matched fittings, connector, price Delivery was the issue with competitor switch. Local Channel Partner stocked switch for fast delivery

Application – Gas Mixers u Welding Shield Gases n u Other Gas Mixer Applications n n n 13 Used for mixing 2 and 3 gases for MIG and TIG welding applications Food Packaging Furnace Atmosphere Leak Detection Blanketing Atmospheres Medical

Application - Gas Mixers u u Switch is used for surge tank pressure control Digital Pressure Readout n No more moving needle on a mechanical gauge Surge Tank Pressure Gauge Surge Tank u u u 14 Eliminated Set Point Drift Diagnostics - LED lights indicate switch state Long Life - switch should last life of equipment

Application – Industrial Air Compressor u u 3 -Stage High-Pressure Reciprocating Compressor Starts & Stops Compressor Based on Pressure Drop Registers Outlet Pressure When Pressure Reaches 4500 psi: n 15 Signal is sent from switch to PLC to shut down system. At 4150 psi, signal is sent to PLC to start

Application – Industrial Compressor u Displaced Competitor: n n n 16 Better accuracy than competitor No set point drift Digital readout

Compressors – Breathing Air u u Compressor for Scuba Diving Benefits n n n 17 Dual Switch Digital Readout Compact Size Programmability Stainless Steel Housing

Benefits – Selling Points u How Do I Sell It? n Maintenance Savings Does not need to be tested and adjusted repeatedly like an electromechanical switch; in most situations an electronic switch is calibrated once. Changing or verifying settings only takes seconds, and does not require system shutdown n 10 -error Internal Watchdog allows companies to skip preventative maintenance; in the event of malfunction, error is displayed or it can be set to send an alarm. n n Set switch to “Read Only” Anyone can view all parameters, including error codes, but cannot change settings – gives users much more information than a “blind” electromechanical switch n Display menu always comes back to the start – easy to use n 18

Benefits – Selling Points u How Do I Sell It? n Great for Aftermarket n OEM’s often install low-cost mechanical switches to cut costs; – in demanding high-cycle applications or where multiple setpoints are required or preventative maintenance is an issue, solid state switches can be a long-term cost saver – Some OEM’s offer solid state switches as an option n Plant Upgrades n Not a lot of new projects right now – Some plants are focusing on maintenance and upgrades – the perfect opportunity to make the case for switching from electromechanical to electronic switches n Sell to the right level – Easy to sell electromechanical switches to the technician; – Sell electronic switches to the manager 19

Benefits – Selling Points u How Do I Sell It? n Understand the Product Work with a demo to understand functions/menus n Ask Channel Partner manager for help with product n New online features coming to explain features/functions n Call Neal Lightfeldt with problems/requests (323) 583 -6228 n 20
