Ambient Ozone Sensors

Industrial sensors and transmitters for precise measurement of ozone gas in plant rooms and enclosed spaces. The sensors will have relays, alarms and other controls to detect leakage and concentrations. Robust, reliable and accurate, this product is designed to monitor and measure ambient ozone continuously and in real-time.

Features:

  • Industrial strength, water resistant enclosure.
  • Large digital display, auto-ranging (0-50ppm) w/ backlight.
  • Easy front panel access to set points and relays.
  • Precisely adjustable max, min, and fail time set points.
  • Failure alarm if ozone remains outside control range.
  • Front panel generator control cutoff switch for easy maintenance.
  • User selectable PPM ranges for analog output (4-20 mA and 0-2 VDC)
  • OSHA 0.1 ppm safety limit light.

Specifications:

  • Enclosure: Wall mounted polycarbonate enclosure resists water spray and splash (NEMA 4X).
  • Size: H = 6.3”/160mm, W = 6.5”/166mm, D = 4.6”/118mm.
  • Power in: 12-24 VDC.
  • Power out: +5 or +12-24 VDC to sensor.
  • Data in: RS-232 serial data from remote sensor module (SM-4 or equivalent).
  • Data out: RS-232, 9600 Baud 8N1 format.
  • Analog out: 0-2 V and 4-20 mA, internal jumpers select full scale PPM range.
  • Control in: Generator enable (contact closure).
  • Control outputs: Relays, 10A @ 25VDC, 0.25A @ 250VDC, 2.0 KVA AC (resistor).
  • Relay functions: Ozone generator control, >100 PPB safety limit, failure to control.
  • User controls (internal): MAX set point, MIN set point, FAIL time, increase, decrease.
  • Numeric display: Four digits, 0.5”/12mm, auto-ranging, with backlight.
  • LED indicators: Sensor, above MAX, below MIN, >100 PPB, generator on, failure
