OXY-LC Oxygen Sensor Interface Board Description
The OXY-LC Oxygen Sensor Interface Electronics provides the necessary electronics to power and control SST range of zirconium dioxide (ZrO2) sensors.

The OXY-LC Oxygen Sensor offers various user configurable output variants RS485, PWM, 0-10Vdc and 4-20mA. The RS485 Modbus RTU Protocol offers various benefits over other output types but most importantly it allows complete control of the sensor operation and access to all available information including sensor diagnostics, barometric pressure and pressure sensor temperature.

The adaptive software filtering which enables it to provide a fast response coupled with a stable oxygen output. In addition to this, the OXY-LC Oxygen sensor interface electronics offers a high accuracy linear output for all of our zirconium dioxide oxygen sensors.

The built in pressure sensor allows for barometric pressure compensation and the interface mounted screw terminals offers easy wiring with reverse voltage and transient overvoltage.

Oxy-comm zirconia oxygen analyser description
The oxy-comm zirconia oxygen analyser is designed for controlled atmosphere applications such as refrigerated transportation containers and fire prevention.

The oxy-comm zirconia oxygen analyser combines a high accuracy zirconium dioxide oxygen sensor with a networkable, fault tolerant rs485 interface. The oxygen analyser is mounted under a stainless steel hood to protect it from the environment. The ip65 waterproof die-cast aluminium housing accommodates the electronics and has a 4-pole m12 connector to allow multiple devices to be interconnected.

The oxygen sensor inside oxy-comm uses a unique closed loop measurement system. While oxy-comm continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures. Due to the innovative design, the oxy-comm zirconia oxygen analyser does not require a reference gas. Low drift means these products do not require frequent calibration but when they do, it is an extremely simple process which can be performed in fresh air which means there is no need for expensive calibration gases.

The oxy-comm zirconia oxygen analyser has an 8 to 15vdc supply voltage range with reverse polarity and transient overvoltage protection. The oxygen analyser is barometric pressure compensated and can be calibrated in fresh air (20.7% o2) or to any other known o2 concentration.

Oxy-comm-rs485 zirconia oxygen analyser features
* 8-15v dc supply voltage with reverse polarity and transient overvoltage protection
* networkable, fault tolerant rs485 interface, short circuit and overvoltage protection
* can be calibrated in fresh air (20.7% o2 ) or to any other known o2 concentration
* barometric pressure compensation

Oxy-comm-rs485 zirconia oxygen analyser applications
* refrigerated transportation containers
* protecting historical artefacts against oxidation
* fire prevention in facilities such as server rooms, or document storage
