Development of an energy-harvesting toxic and combustible gas sensor for oil and gas industries



Wireless gas leakage detection systems are necessary in the oil and gas industry (OGI). This is because they are more flexible in terms of installation and maintenance.

However, wireless combustible gas sensors have an average life span of 2 years. This is because of the huge energy consumption of the gas sensors.

In this paper, a wireless gas sensor network (WGSN) combining adaptive sleep cycle and energy harvesting is developed. The system is able to reach a life span of 5.5 years with the help of solar panels.

Modularer CO2 Transmitter



The modular CO2 Transmitter EE870 from E + E Elektronik now measures CO2 concentrations up to 5% CO2 (50,000 ppm). The extended range is the EE870, consisting of CO2 sensor, converter board and connecting cable, now even more versatile.

The replaceable CO2 sensor EE871 with autocalibration uses an infrared measuring principle (NDIR two-beam method) that is particularly insensitive to contamination. Aging effects are compensated automatically, resulting in excellent long-term stability. The CO2 transmitter is ideal for demanding applications.

The multipoint CO2 and temperature adjustment ensures excellent accuracy over the entire temperature range of -40 ... 60 ° C. In addition offers the IP65 sensor housing with replaceable PTFE filter excellent protection against contaminants.

Quick and simple integration of optical oxygen sensors into glass-based microfluidic devices



This work presents a novel simple and inexpensive technique for integration of optical oxygen sensors into microfluidic chips made of glass. The channels of chips are coated with conjugated polymeric nanoparticles containing a covalently grafted oxygen indicator. The resulting layer of physically adsorbed nanoparticles shows excellent stability in buffers of various pH and in presence of a surfactant without noticeable leaching.
                                                      
The integrated sensors feature ultrafast response (less than 0.2 seconds) and repeatable quenching behavior when exposed to different concentrations of oxygen present in air or aqueous solutions. They can be read-out either in lifetime or in ratiometric intensity modalities using unsophisticated, compact and low-cost fluorescence detection systems such as a dual RGB/NIR camera or a phase fluorometer.

We also present a new technique for modification of smooth glass surfaces based on in situ generation and deposition of dense silica microparticles, which act as an adsorbent for the oxygen-sensitive nanoparticles. This modification dramatically improves the loading with the nanoparticles due to increased surface roughness and maximized contact surface area.

Finally, packed-bed micro reactors with integrated oxygen-sensing layers and filled with silica beads containing the enzyme immobilized on its surface are demonstrated to have high potential for investigation of enzymatic activity.



Alcohol sensor based on membrane-bound alcohol dehydrogenase



Ethanol is determined by a sensor system using purified, immobilized mernbrane-bound alcohol dehydrogenase frorn Gluconobacter suboxydans, attached to a platinum disk electrode (3 mm diameter), and covered with a dialysis membrane.

Hexacyanoferrate (III) is used as the redox acceptor. To correct for the influence of interfering substances, this alcohol sensor is compensated by a control electrode which has no immobilized enzyme. The potential of these platinum electrodes was set at + 350 mV vs. Ag/AgCl. Linearity was observed in the range 0.1–5 mM ethanol, the response time was less than 5 min, the maximum sensitivity was obtained at 45°C and the optimum pH was in the range 4.5–5.5.

The sensitivity decreased to 80% of the initial value after 1 month at 30°C. When the alcohol sensor system was applied to the determination of ethanol in alcoholic beverages, a good correlation was obtained between the results and those obtained by gas chromatography.

Optical Oxygen Sensors for Applications in Microfluidic Cell Culture



The presence and concentration of oxygen in biological systems has a large impact on the behavior and viability of many types of cells, including the differentiation of stem cells or the growth of tumor cells.

As a result, the integration of oxygen sensors within cell culture environments presents a powerful tool for quantifying the effects of oxygen concentrations on cell behavior, cell viability, and drug effectiveness. Because microfluidic cell culture environments are a promising alternative to traditional cell culture platforms, there is recent interest in integrating oxygen-sensing mechanisms with microfluidics for cell culture applications.

Optical, luminescence-based oxygen sensors, in particular, show great promise in their ability to be integrated with microfluidics and cell culture systems. These sensors can be highly sensitive and do not consume oxygen or generate toxic byproducts in their sensing process. This paper presents a review of previously proposed optical oxygen sensor types, materials and formats most applicable to microfluidic cell culture, and analyzes their suitability for this and other in vitro applications.

A contactless conductivity sensor based on capacitively coupled principle



The existing capacitively coupled contactless conductivity detection (C4D) sensors are mainly used to detect the conductivity/ion concentration in capillary tube.

A new sensor for conductivity measurement in large-scale pipes is developed based on the C4D technique. A quartz crystal is introduced to eliminate the influence of the coupling capacitances. Meanwhile, a quartz crystal oscillator is designed to simplify the sensor structure and provide the excitation signal with highly stable and accurate frequency.

Experimental results indicate that this sensor obtains satisfactory accuracy when measuring conductivity in large-scale pipe (5.5 mm i.d. and 7.5 mm o.d.). In the range of 1-200 mS/cm, the maximum relative measurement error is less than 2%. The developed conductivity sensor provides useful reference for contactless conductivity measurement in industrial field.

Position Sensors



In this tutorial we will look at a variety of devices which are classed as Input Devices and are therefore called “Sensors” and in particular those sensors which are Positional in nature. As their name implies, Position Sensors detect the position of something which means that they are referenced either to or from some fixed point or position. These types of sensors provide a “positional” feedback.

One method of determining a position, is to use either “distance”, which could be the distance between two points such as the distance travelled or moved away from some fixed point, or by “rotation” (angular movement). For example, the rotation of a robots wheel to determine its distance travelled along the ground. Either way, Position Sensors can detect the movement of an object in a straight line using Linear Sensors or by its angular movement using Rotational Sensors.

The Potentiometer

The most commonly used of all the “Position Sensors”, is the potentiometer because it is an inexpensive and easy to use position sensor. It has a wiper contact linked to a mechanical shaft that can be either angular (rotational) or linear (slider type) in its movement, and which causes the resistance value between the wiper/slider and the two end connections to change giving an electrical signal output that has a proportional relationship between the actual wiper position on the resistive track and its resistance value. In other words, resistance is proportional to position.

Potentiometer
Potentiometers come in a wide range of designs and sizes such as the commonly available round rotational type or the longer and flat linear slider types. When used as a position sensor the moveable object is connected directly to the rotational shaft or slider of the potentiometer.

A DC reference voltage is applied across the two outer fixed connections forming the resistive element. The output voltage signal is taken from the wiper terminal of the sliding contact as shown below.

This configuration produces a potential or voltage divider type circuit output which is proportional to the shaft position. Then for example, if you apply a voltage of say 10v across the resistive element of the potentiometer the maximum output voltage would be equal to the supply voltage at 10 volts, with the minimum output voltage equal to 0 volts. Then the potentiometer wiper will vary the output signal from 0 to 10 volts, with 5 volts indicating that the wiper or slider is at its half-way or centre position.
