我也要出現在這里

OS-4像一個自動調溫裝置,控制臭氧發生器的開關和報警,報警基于內部可以設定的兩個設置點,一個用來打開臭氧發生器或報警,另一個關閉發生器。另外還有0.10ppm點持續監測傳感器周圍的臭氧,該濃度對人體(健康)有影響。標準量程:0.03-10ppm,可顯示到20ppm。SPDT輸出繼電器信號的能力達5安培@250VAC或驅動一個1/8馬力的馬達。OS-4也有數字、電壓和4-20mA輸出以驅動馬達和控

Acts like a thermostat to control ozone generators and alarms based on adjustable ozone concentration set-points. Ozone ppm readout via digital meter. Simple and effective.Features:

 

  • Easy to install. Minimal adjustments.
  • Sensor is in a replaceable precalibrated module. Separated by a cable, the instrument is not in the high ozone area.
  • Sensor reading is temperature and relative humidity compensated.
  • Replacement sensor is miniature, low cost, precalibrated and also fits our A-22.
  • Operates from 12-24 VDC or from AC adapters available worldwide.
  • Alarms, data loggers, and other accessories available.
  • Programmable turn-on and turn-off set-points.
  • Indication when .1 ppm safety standard exceeded.

Typical Applications:

  • Monitor ozone levels in treatment storage areas for fruits, vegetables, and other agricultural products. Monitor ozonated HVAC systems. General monitoring at .03-20 ppm.
  • Control the output of ozone generators using the set-point controlled relay in the OS-4.
  • Use as either ozone leak alarm or ozone failure alarm for all sizes of ozone generators.
OS-4 host unit normally located outside of the ozone treatment area.
  
Specifications:

 

  • Range and Accuracy: .03-20 ppm of ozone.
  • Accuracy: 10-15% (Depends on application).
  • Temperature and humidity: 5-40°c 20-95% RH
  • Measurement Principle: HMOS (heated metal oxide semiconductor) sensor.
  • Size: 127 × 64 × 42 mm (5 × 2.5 × 1.625 in).
  • Weight: 200 gr (7 oz)
  • Power Requirements: 12-24 VDC, 300 mA. AC adapters available.
  • Output control: SPDT non-latching relay. Contacts rated at 5 amps, 250 VAC.
  • .1 ppm danger alarm: Panel LED and SPDT relay 5 amp contacts.
  • Connections: Terminal blocks for relay output and DC input. 2.5 mm DC power jack for AC adapter.
  • Indicators: Green LED: instrument on. Yellow LED: >.1 ppm. Red LED: generator on.
  • Outputs: 0-2 V, 4-20mA, RS-232 digital.
  • Case: Flame-resistant ABS with mounting ears.
  • Not recommended for use in the presence of strong acid gases or VOC fumes.
