Product Specification

LuminOx
LuminOx Evaluation Interface Board


GENERAL DESCRIPTION

The LuminOx Sensor family is a range of factory calibrated oxygen sensors which measure ambient ppO₂ levels using the principle of fluorescence quenching by oxygen.

The LuminOx Evaluation interface Board has been designed to allow customers to quickly and easily evaluate the sensor with the minimum of effort or design work

The LuminOx Evaluation Kit simultaneously provides three outputs;
• RS232 (serial interface voltage levels)
• RS485 (Modbus RTU) port allows multiple sensors to be addressed on a bus
• 0-5V Analogue output for basic measurements of oxygen only

BENEFITS
• Converts the LuminOx TTL level 
• RS232 output into 3 standard industrial outputs
• Auto detects ppO2 or O2% variants of LuminOx Sensor.
 
APPLICATIONS 
• Oxygen Detection 
• Portable Equipment 
• Breathing Apparatus
• Inerting
• Medical
• Lab Equipment
• Agriculture
• Incubation
• Fire Prevention

The LuminOx range has been designed as an alternative to electrochemical sensors but with the benefits of RoHS compliance, long life and complete environmental compensation built-in.

The sensor is available with and without a built-in barometric pressure sensor. LuminOx’s native measurement is partial oxygen p ressure (ppO2) in mbar. By incorporating a barometric pressure sensor, LuminOx is able to measure O 2 vol. % in addition to ppO2

Unlike electrochemical sensors, LuminOx requires no additional signal conditioning circuitry and connects directly to the customers microcontroller via 3.3V-level RS232 link. This reduces costs and simplifies system design.
However, to enable customers to quickly evaluate the sensor, the LuminOx Evaluation Interface Board has been developed. It’s three Output channels are explained below. Wiring details are show on page 7.
