  2. 2. Why The New Series?Product Line Growth Additions Included 3% Accuracy Voltage Outputs Sintered Filter OSA) Passive Temperature Outputs Series RH Model Numbers Not Friendly For So Many New Options
  3. 3. Smart Model ConfigurationRHP(2 or 3) Sensor Accuracy (W, D, O, S, F, R) Housing Configuration (1,2,3,4) Humidity Output (0,1,2,3,4,A,B,C,D,E,F) Temperature Output (-LCD) Options
  4. 4. Key Additional FeaturesAvailability of Passive Thermistor and RTDOutputs 10KΩ Type II NTC Thermistor 10KΩ Type III NTC Thermistor 3KΩ NTC Thermistor Pt100 Ω RTD Pt1000 Ω RTD 20KΩ NTC Thermistor Allows Use With Most Building Management Systems Without Using an Additional Analog Input
  5. 5. Key Additional Features Ability to Field Replace Sensors Saves Cost of Purchasing New Transmitter Upon Sensor Failure Reduces Cost If Wrong Accuracy or Temperature Sensor is Ordered Surface Mount Sensor More Compact
  6. 6. Key Additional FeaturesRemovable Terminal Blocks with LargerScrew Terminals Reduces Installation Time by Making Attaching Wires Easier0 to 5 V Output Option Increases the number of Building Management Controllers That Transmitter is Compatible With
  7. 7. Additional Features – Duct ModelsFixed Mounting Bracket Wider Mounting Bracket Is Easier to Screw to Duct Most Ducts are over 228 mm in Diameter or DepthFixed Mounting Bracket Reduces InstallationTime Since Installer Does Not Having toRemove Mounting Flange From the ProbeDuring Installation
  8. 8. Additional Features – Duct ModelsRemovable Cap and Sintered Filter Allows Access To Sensor So It Can Be Changed Sintered Filter Can Be Changed or Cleaned When PluggedGasket Around Probe Circuit Board Prevents Air From Conduit Entry Affecting Humidity / Temperature Readings On Return Air Duct Installations
  9. 9. Additional Features – OSA ModelsFactory Mounted Radiation Shield Radiation Shield Protects Against Error Caused By Radiated Heat Shield Can Be Mounted At Dwyer Factory or Field Installed on Sintered Filter OSA ModelsRadiation Shield Provides Better Air FlowAcross the Sensor to Improve Accuracy ofReadings and Allows The Sensor to BeMounted Anywhere
  10. 10. Additional Features – Wall Models New Dwyer Designed Housing Well Ventilated Housing Snap in Temperature Sensor Board Terminal Block On Back Plate Top Hinged Cover For Easy Installation New Housing Provides Better Air Flow to Give More Accurate Readings and Requires Less Installation Time
  11. 11. Additional Features – Wall Models Optional LCD Display Integral or Remote Displays Both Temperature and Humidity Field Selection of Engineering Units Field Selection of Humidity or Dew Point Remote Display Allows Users to Use One Display to Check Multiple Transmitters to Save on Product Costs
  12. 12. Additional Features – Wall ModelsOptional Universal Current / VoltageOutputs Field Selection of 0 to 5 VDC, 0 to 10 VDC, or 4 to 20 mA For Temperature and Humidity Outputs Can Also Be Inverted (5 to 0 VDC, 10 to 0 VDC, 20 to 4 mA)Prevents ordering wrong output for theproject!!!
  13. 13. Features LostNo Adjustable Mounting Flange Not Able to Mount to Smaller Than 228 mm Due to Screw On Cap Must Be Bigger
