Sensor Technology 61 New Hydrogen Sensor
Now Available Tyco Gas & Flame Detection (USA) is pleased to announce that the Meridian Hydrogen (H2) Sensor is now available.
The Meridian Hydrogen sensor comes standard with two user selectable gas ranges: 4% by Volume or 1% by Volume, and is ideal for Hydrogen detection in environments where Catalytic bead sensor use is impractical, or available power is limited.
This new sensor follows other available Meridian sensor features including: Range Invariant calibration, true Hot Swap replacement, and the ability to calibrate in the lab and put it quickly into operation in the fi eld. The sensors employ an electrochemical sensing element that needs recalibration just once every three months for optimum performance.

40287pr@reply-direct.com Proven and Improved Series of Differential Pressure Sensor
Sensirion presents the new differential pressure sensors of the SDP800 series. The sensors are the result of more than 15 years of experience in measuring air fl ow to millions of HVAC systems, car engines and patients. They consequently utilise the successful features of the SDP600 differential pressure sensor and come in the same proven housing, which enables easy integration. The next generation chip combines outstanding accuracy and long-term stability with extended functionality and higher measurement speed at even lower cost. Thus, the new SDP800 is the reliable and advanced solution for the most demanding, but cost-sensitive HVAC applications, such as VAV controllers and burners.
The new differential pressure sensors of the SDP800 series offer excellent repeatability and measurement speed up to 2 kHz. The fully calibrated and temperature-compensated sensors are available in numerous versions that differ in pressure range, pneumatic connection and output signal. Whereas the analog version provides a confi gurable analog voltage output, the digital version features different measurement modes, smart averaging functions and multiple I2C addresses. Both versions come with either 125 Pa or 500 Pa bidirectional pressure range and provide a manifold or tube connection.
Like all Sensirion differential pressure sensors, the SDP800 series is based on Sensirion’s patented CMOSens® Technology, which combines the sensor element, signal processing and digital calibration on a small CMOS chip. The differential pressure is measured by a thermal sensor element using the fl ow-through principle. Thanks to this, Sensirion’s CMOSens® differential pressure sensors come with no zero- point drift and outperform traditional piezo-resistive membrane sensors in terms of sensitivity at low differential pressures, offset drift and hysteresis, as well as position sensitivity, shock resistance and temperature variations.
An evaluation kit is available for quick and easy testing of the digital SDP800 sensors. This EK-P5 evaluation kit consists of a SDP810 sensor that is easily plugged into a PC via an USB cable. With the help of the software available online for download, the differential pressure sensor can be tested under realistic conditions by following the simple installation steps. The kit can be purchased directly from Sensirion distributors.

Breakthrough in Low-Power NDIR Gas Sensor Technology The market of gas detection equipment
is evolving at a steady pace and sensor technologies must stick to the cutting edge of progress to stay on par with these advancements. Following well over a decade of intensive research and development, MIPEX has created a unique patented NDIR technology that fuels its line of methane, hydrocarbons and carbon dioxide sensors. The technology has the potential to revolutionize the market of high- precision optical gas sensors for industrial safety thanks to its uniquely low power consumption – substantially lower than in traditional lamp-based IR optical sensors. In absolute terms, power consumption across the entire line does not exceed 3 mW, which makes these products perfectly suitable for wireless and portable gas detectors of the newest generation.

Unrivalled low power hydrocarbon gas sensor
MIPEX-02 3 mW
The MIPEX-02 model is the centerpiece of the MIPEX product line. The dual-beam sensor uses a patented system of miniature mirrors and a LED emitter of a proprietary design operating within a particular spectrum. The durability and long life cycle of the MIPEX-02 sensor is attained through the use of unique components – photo diodes based on thin fi lms of a solid PbSe – CdSe solution that not only offer improved durability, but also up to 10 times more sensitivity than pyro-electric photo detectors. To achieve maximum stability under volatile operational conditions, the sensor signal is further refi ned and linearized by special algorithms using an integrated microcontroller.
All of above ensures maximum accuracy of measurements in the harshest environments with irregularly changing temperature conditions.
MIPEX-02 boasts “Ex ia” intrinsic level safety with all of its components securely packed into a compact, industry standard size (∅20.2×16.6 excluding pins) stainless steel housing. Communication with the host device is carried our via a digital UART interface.
MIPEX-02 NDIR sensor is a smart device capable of running self-diagnostic routines, identifying errors and taking preventive measures to fi x them, automatically adapting to changing environmental conditions and providing stable output to the host unit. The product is available in several factory confi gurations fi ne-tuned for particular areas of applications and detection parameters.
MIPEX-02 provides a wealth of opportunities to the manufacturers of gas detection equipment, starting from record-low power consumption and intrinsic durability and all the way to full compliance with standards and best design practices.
