SST Sensing's Zirconia Oxygen Sensor System offers a complete 25% or 100% oxygen level measurement solution by removing the need for customers to develop their own electronics. It can be used in combustion control systems, coal, oil, gas, biomass or in oxygen generation systems.

The system employs a well proven, zirconium dioxide element at its heart and, due to its innovative design, does not require a reference gas. This, along with its rugged stainless steel construction means the sensor can be used in extreme temperatures ranging from -100°C to 250°C and aggressive environments.

When connected to the OXY-LC interface board (required), the OXY-O2S-FR oxygen sensor measures oxygen concentrations of 0.1% to 25% or 0.1-100% solution with a 4-20mA analog output. An RS485 output interface board is also available with selectable 0.1% to 25% or 0.1-100% ranges.

Features

  • Non-depleting zirconium dioxide technology gives long life span
  • Integrated heating element measures in extreme cold
  • All stainless steel construction
  • Variety of probe mounting positions available

Models

Zirconia Oxygen Sensor System - consists of a probe and interface board. Probe and Sensor Interface Board must be both be purchased for a complete sensor system.

OXY-O2S-FR-T2-18BM-C - Zirconia Probe -  28mm zirconium dioxide oxygen sensor with threaded probe for easy installation. Cable length 1m (39.4 in.)

OXY-LC-A25-455 Oxygen Sensor Interface Board - 0.1-25% oxygen range from 4-20mA output. Removes the need for customers to develop their own electronics to take readings from the probe.

OXY-LC-A100-455 Oxygen Sensor Interface Board - 0.1-100% oxygen range from 4-20mA output. Extended range when measuring oxygen in bulk storage tanks.

OXY-LC-485 Oxygen Sensor Interface Board - 0.1-25% or 0.1-100% oxygen range (user selectable on board) with RS485 output. Can be calibrated to any known oxygen gas.
