62 Focus on Sensor Technology Tried and Tested Oxygen Sensor


Exceeds Expectations MEMBRAPOR released their O2


sensor in 2011. After 6 years this O2


/M-100 oxygen sensor has


successfully established itself in the market.


The expected operation life and signal stability have exceeded all expectations. This high quality sensor is extremely durable and performs day in and day out, over a period of three years a signal drift of less than 4% is observed.


The sensor has no consumable parts and is based on MEMBRAPOR’s true 3-electrode technology. Although this electrochemical sensor needs a bias voltage, it is ready to be used within 2 minutes after a power cut off and it will respond fast.


The O2


(offset) of only ≤ 0.1% vol. O2 Complying with RoHS, the O2


in the range of 0 - 1% with a resolution ≤ 50 ppm. Although it is highly sensitive, the sensor will not be damaged when exposed to ambient air. It is highly stable and exhibits a life time of several years, like the O2


O2 /M-100.

/M-100 is best in class performance for fast response time of t90 < 10 sec, low zero current and high resolution of ≤ 0.05% vol. O2


/M-100 is perfectly positioned to be your reliable sensor for O2


in the range of 0 - 30%. To measure trace concentrations of oxygen a second type of sensor is available: The O2

Low Power Optical Gas Sensing Systems


Enabled with New Range of IR Sources Cambridge CMOS Sensors (CCS) re- cently announced the launch of its range of µBright infrared sources, the latest of its gas sensor components for low-power, long life optical gas sensing solu- tions. Designed to oper- ate across the wideband IR range (2 to 14µm) the µBright sensors can be used to continually sense gases, such as carbon dioxide, and etha-


This table indicates the key product parameters for the CCS11x µBright™ family of infrared sources


nol vapours in NDIR (nondispersive infrared) systems at low power.


The CCS11x family of IR sources incorporate a new patented plasmonic structure, which has a layer of metallic dots with a defined geometry which creates a resonant effect, increasing the optical emissions of the CCS11x sources. The devices use CCS’s patented micro-hotplate design to deliver high optical emissions across a broad range (2µm to 15µm) of IR wavelengths with a very stable, low drift output. The plasmonic structure and the micro-hotplate are fabricated using a standard CMOS process.


ALCOHOL SENSORS: the world’s fi rst skin contacting, transdermal alcohol sensor; and an all new high temperature resistant breath alcohol sensor.


OXYGEN SENSOR: ready soon, the world’s fi rst lead-free, industry compatible, two pin, fuel cell oxygen sensor.


FORMALDEHYDE PRE-CALIBRATED MODULE: 0.03 – 2 ppm. Delivers a pre-calibrated formaldehyde ppm output directly. For automotive air quality applications a high temperature (85C) resistant version will be offered.


FOOD FRESHNESS: for installation in smart refrigerators. LOW COST CARBON MONOXIDE SENSOR: DS dry composition, leakproof. HYDROGEN SENSOR: ready soon, an industry standard three pin sensor.

The CCS11x family of components have an inherently low thermal mass which allows for rapid heating to high temperatures (up to 600oC), allowing pulse mode operation at high frequencies and low power consumption. Features and benefits of CCS11x µBright IR Sources include: Stable output with low drift – low resistance drift over lifetime removes need for compensation, Fast switching – Up to 38Hz at 50% modulation depth, High IR radiation output – Up to 600oC oper- ation with emissivity at 0.8 at 4.26µm, Superior efficiency – Pulse mode operation, and a Proven technology platform – Designed for high volume and reliability (>5year lifetime).


Jess Brown, Sales and Marketing Director at CCS said: “We are pleased to launch the CCS11x, the new µBright range of Infrared sources - our latest generation of IR components for optical gas sensor solutions. These devices will enable our customers to have lower power, smaller optical gas sensing products which can be used to monitor specific gases such as carbon dioxide and also to detect greenhouse gases and refrigerants such as Freon for demand control ventilation, building monitoring, automotive cabin control, and industrial safety and security applications.”


The CCS112A, CCS113A and CCS114A are available for sampling now in TO packages (TO46 and TO39).

CAPBs are compact measuring instruments with pluggable sensor modules for a wide variety of measurements. The modularity allows for easy, cost-effective extensions of the CAPBs measuring instrument - plug & play at its best. Mobile devices (Android, iOS) control the CAPBs and display the measured values. In addition, CAPBs allow you to turn BlueLine measuring instruments into multi-purpose measuring instruments. CAPBs cover a vast range of applications with uniform operation. CAPBs are yet another “Innovation Made in Germany” by SYSTRONIK GmbH (member of the AFRISO-EURO-INDEX group).
