OEM-1,2 vs the SM-50 OEM Ozone Sensors

The OEM-1 and OEM-2 and SM-50 are all Original Equipment Manufactures (OEMs) Ozone Sensors that are designed with state of the art sensor technology that can be integrated into your own equipment.  OEM Sensors are a great addition to any Ozone System to help ensure any ozone leaks are detected and the Ozone Generation system is shut off.  The OEM sensors can be integrated into your system to control your Ozone Generation system and turn it off and one based on your preset levels. Below we will lay out the benefits and differences between the EcoSensors OEM-1&2 and the Aeroqual SM-50 OEM Ozone Sensors.

OEM-1&2

OEM-1

 

OEM-2

 

Abilities/Features:

  • 3 range options: 0-0.1ppm, 0-1ppm, 0-10ppm of ozone
  • Can control Ozone Generators and alarms based on an adjustable ozone concentration set point
  • Sensor replacement (SM-1) is simply plug-n-play
  • Pre-calibrated sensors
  • OEM-2 has 4-20mA output
  • Sensors can be located up to 25ft (8meters) away from the board using an extension cable
  • Base Board incorporates power supply, final signal processing, set-point controls and output relay
  • HMOS (Heated metal oxide semiconductor) Sensor

Disadvantages:

  • The OEM-1&2 are being discontinued October 2017 with the new OEM-3 being released mid-November 2017. The replacement sensors for the OEM-1&2 (SM-1) are no longer available for the OEM-1&2, and will need to be replaced with the new OEM-3.
  • Accuracy 20%

 

SM-50

SM50 Sensor & Board

Abilities/Features:

  • 3 range options: 0-0.15ppm, 0-0.5ppm, 0-10ppm of ozone
  • Analog voltage
  • Relay and status indicators
  • Optional RS232 or RS485
  • Factory calibrated and ready to use
  • Preloaded firmware that optimizes measurements and enhance data output
  • User set points to trigger alarm
  • GSS (Gas Sensitive Semiconductor) Sensor
  • Optional use of: 2 analog voltages inputs and 2 GPIO which can connect a temp/RH sensor
  • Accuracy +/-10%

Disadvantages:

  • Complete board needs to be replaced when sensor goes bad.

Why use OEM Sensors?

Ozone Sensors should be used in EVERY Ozone Generator to ensure safety for anyone that might be exposed to unsafe levels of ozone.  OSHA has regulations for ozone and proper safety precautions that should be set in place, such as an ozone sensor to shut of Ozone Generator when unsafe levels are detected, is one of them.  If regulations are not followed, it could cost your company a lot of money.  See this story that talks about the fines from OSHA due to worker safety levels.
