LuminOx Fluorescence Optical Oxygen Sensor (O2 Sensor) - LOX-02

LuminOx Fluorescence Optical Oxygen Sensor (O2 Sensor)

LOX-02 LuminOx Fluorescence Optical Oxygen Sensor (O2 Sensor) description

The LuminOx Family is a range of factory calibrated optical sensors which measure ambient O2 levels using the principle of fluorescence quenching by oxygen.

Our unique patented process allows us to produce an oxygen sensor that benefits from low power, traditionally associated with electrochemical sensing devices, while providing a much longer lifetime due to the non-depleting sensing principle.

LuminOx unlike other sensor technologies is stable and robust, it is RoHS compliant as it does not contain lead or any other hazardous materials and has negligible cross sensitivity.

LuminOx can be purchased as a single optical sensor, or as part as an evaluation kit which includes the LuminOx Sensor Evaluation Interface Board, which was designed to allow customers to easily evaluate the sensor with minimum effort or design work.

LuminOx Optical Oxygen Sensor Evaluation Interface Board

LOX-EVB LuminOx Optical Oxygen Sensor 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

LOX-EVB LuminOx Optical Oxygen Sensor Evaluation Interface Board BENEFITS
• Converts the LuminOx TTL level 
• RS232 output into 3 standard industrial outputs
• Auto detects ppO2 or O2% variants of LuminOx Sensor.

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 O2 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.

Rain Collector Sensor - Rainfall Sensor

 

Rain Collector Sensor

 

Rain Collector Sensor Rainfall Sensor
This self-emptying, tipping bucket style rain collector utilizes an 8" diameter openning to meet NWS specifications for statistical accuracy. Rainfall is gathered in the collecting bucket and funnels through a small openning into a tipping mechanism. When the mechanism has 1/100th of an inch of water in it, it tips.  A count is then transmitted to an indicator and the water emptys from the tipping mechanism, through the bottom of the collector bucket to the outside.

Rain Collector Sensor Rainfall Sensor
Tipping bucket, self-emptying rain collector.  8" diameter openning meets NWS specifications for size and accuracy.
Dimensions: 8.63" O.D. x 7.88" Deep
Weight: 1.77 lbs.

The rainfall collector requires no manual emptying. Each tip of the bucket is equivalent to 1/100th of an inch of rain. It utilizes a normally open circuit that is momentarily closed each time it tips.  As such, it can be connected to any simple counting circuit, including Maximum's Rainwatch indicator.

Rain Collector Sensor Rainfall Sensor Features
Outside rainfall collector meets NWS specifications for size and accuracy, and is self-emptying for your convenience.
The collector bucket can remain outdoors year-round.  Freezing weather will not damage the collector, but readings of snow or freezing rain are not to be considered accurate readings of rainfall. 
Ships complete with 60', 22 AWG, 2-wire, UV protected cable. 

Rain Collector Sensor Rainfall Sensor Specifications 
* Type: Tipping bucket, self-emptying
* Dimensions: 8.63" O.D. x 7.88" Deep
* Weight: 1.77 lbs.
* Cable: 60', 22 AWG, 2-wire, UV protected
* Collector Diameter: 8.00"
* Collector Height: 8.00"
* Mounting Diameter: 9.60"
* Housing Materials: ABS Plastic
* Housing Color: Dark Green or Black
* Accuracy: +/- 1% at rates of rainfall up to 1" per hour if collector is properly maintained.
* Required Maintenance: Keep the collecting area and screen free of debris (leaves, branches, etc.). Glean the tipping bucket surfaces and the external surfaces of the collector occasionally with a mild detergent.
* Counting Mechanism: Self-draining, tipping bucket design. The mechanism is factory calibrated so that it automatically tips every 0.01" when installed on a level surface. As the bucket tips a magnet passes back and forth in front of a reed switch. The reed switch is activated as the magnet passes by causing a normally open circuit to be closed momentarily. Each time the circuit is closed the digital readout counts up 0.01".
* Electrical Characteristics :  
     Switched current: max 500 mA
     Switched voltage: max 200 VDC
     Contact Resistance: max 100 mOhm
     Contact Capacitance: max 0,25 pF 

 

OXY-Flex Oxygen Analyser

Le 25 août 2017, 11:46 dans Humeurs 0

The OXY-Flex Oxygen Analyser is suitable for measuring in oxygen closed systems, such as ventilation pipes and boiler exhaust flues. 

OXY-Flex Oxygen Analyzer Zirconia O2 Sensors

 

The OXY-Flex Oxygen Analyser is designed to measure the oxygen concentration in air or gas mixtures with temperatures of -100 to 400⁰C. The oxygen analyser employs a well proven, small zirconium dioxide based element at its heart and due to its innovative design does not require a reference gas. The oxygen sensor element is mounted in the tip of the stainless steel probe and is protected by a sintered stainless steel cap. The IP65 waterproof die-cast aluminium housing accommodates the electronics and provides the interface for the customer to connect to.

The OXY-Flex Oxygen Analyser uses a unique closed loop measurement system. While the sensor continuously measures the oxygen level, a heartbeat signal is also generated providing an immediate warning of any failures.

The OXY-Flex can be configured to output measuring ranges of 0-25% O₂ or 0-100% O₂. The entire measurement range is linear in both cases. The outputs can be configured to either 4-20mA and 0-10Vdc outputs or an RS232 serial communications interface.

Typical applications include; combustion control of industrial boilers, burning oil, gas, coal or biomass; incubators; composting probes and welding equipment.
