· We are often asked why a portable gas monitor sensor fails--especially when the instrument has hardly been used. This issue seems to be a source of endless frustration for those who aren't intimately familiar with gas detection technology. The first thing we need to understand is how gas sensors …
fraction to facilitate individual rate measurement (oil, water, gas), as well as DTS for thermal profiling, and qualitatively identifying other well problems. For the single point sensors described above, it is necessary to predetermine where in the well the sensors are to be placed. One of the attractions of DTS has always been the ability to measure temperature at any point along the fiber ...
Depending on the sensor (gas detected) this current can be either positive or negative (see . Figure 2 and Figure 3). U1 also ensures that the sensor is loaded by the specified load (R L) and keeps the working electrode at a fixed potential. U2 fixes the specified voltage between the WE and the RE (V WE-V RE = -Vref). It also ensures that no current flows through the RE while providing the ...
All Gas Sensors will require periodic calibration to ensure your gas measurements are accurate and correct. Different gasses, and sensor manufacturers will have differing requirements and methods for calibration. This page will serve to provide general calibration information and links to specific calibration procedures from the sensor manufacturers we represent. Should you have any questions ...
· Sensors for oil wells. Figure 2: Battery-operated drilling sensor sub (DSS) sensors measure and memorize the weight on bit, torque on the bit, pressures and temperatures in both the drill pipe and the annulus for the period of a drill run (about 100 hours).

· Allow the sensors to soak overnight. The gas won't clean the oxygen sensors immediately; you'll need to let them soak for at least 8 hours. At some point while the sensors are soaking in the container of gas, pick the container up and swirl it around several times. This will ensure that all parts of the sensors are being cleaned by the gasoline.
Assemble the sensor in a reactor or any vessel which should have gas inlet and outlet. 4. Connect the two electrical point (made on the sensor material) to electrometer/digital multimeter to ...
Honeywell sensors and switches are an essential element in today’s oil and gas industry, used for many types of upstream applications such as exploration, well development, and production. They need to be built tough to survive some of the world’s most demanding environmental conditions, both on land and offshore while providing accurate and reliable performance. Well stimulation ...

Our sensors are available in variety of formats to satisfy the precise requirements of specific applications. City Technology provides critical gas sensing solutions wherever safety is paramount.
Sophisticated gas sensor systems are being researched for use in medical diagnostic, monitoring, and treatment systems, well beyond their initial use in operating rooms. Gas monitors and alarms for carbon monoxide and other harmful gases are increasingly available for office and domestic use, and are becoming legally required in some jurisdictions. Originally, detectors were produced to detect ...
Electrochemical Sensor: Gas specific electrochemical sensors can be used to detect the majority of common toxic gases, including CO, H2S, Cl2, SiH4 etc. in a wide variety of safety applications. Electrochemical sensors are compact, require very little power, exhibit excellent linearity and repeatability and generally have a long life span, typically one to three years. Response times denoted ...
The 1-Series sensor used by the BW Solo is a single-gas detector developed by City Technology, a Honeywell company with 40 years of experience in manufacturing gas sensors. Sturdy and reliable, these sensors are capable of consistent operation in harsh environments and last up to 5 years, depending on exposure. The compact square design of the 1-Series sensor allows gas to diffuse into …
· How to replace the thermostat/well sensor with an upgraded Honeywell unit. The older units have a flaw that the newer upgraded unit eliminates.
Particularly, gas sensors are widely used to monitor the atmospheric environment or detect hazardous gases [1]. The adsorption of gas molecules onto a polymer surface, a change in mass varies ...

Edinburgh Sensors has actively commercialised this technology over the last 30 years, resulting in a reputation for reliable, accurate, long-term stability and low maintenance gas-sensing products, which have been used extensively over the last 10 years by many of the leading Landfill gas analyser developers, leading to installations worldwide on landfill sites.
Zero calibration: Establishes sensor(s) baseline reading, % oxygen and free of any toxic or combustible gas vapors. To maintain a stable baseline, it is essential to perform zero calibration in fresh air. In the event, fresh air cannot be confirmed, use zero grade air or N2 to perform a detector zero calibration. Perform a zero calibration to reestablish baseline as required, and before a ...
Wet Well Gas Monitoring Strategies. Sample Draw – In a sample draw system, an aspirator or a pump is used to pull a sample from the wet well to the sensor/transmitter location. Sample systems are inherently maintenance intensive on a moisture saturated wet well atmospheres as condensation is the norm. In-line particulate filtering is also ...
· TI offers a Gas Sensor reference design which can be used to monitor gases like carbon monoxide (CO), oxygen (O2), ammonia, fluorine, chlorine dioxide and others in many applications including mining, household CO sensing, healthcare and industrial controls. The design adds a Bluetooth Low Energy (BLE) feature to connect to an iPhone or an iPad via an iOS application running on them. …
· For best results, a full calibration of a temperature sensor is performed at the bench. How to perform the RTD calibration and RTD test. Isolate the sensor from the process. Fully immerse the sensor into a precision temperature source, such as a dry-well or bath capable of covering the required temperature range.
· The sensor has a built in variable resistor that changes its value according to the concentration of gas. If the concentration is high, the resistance decreases. If the concentration is low, the resistance increases. Besides the built in resistor, it is necessary to include a load resistor.
· ZnO based gas sensors operating at room temperature that do not require heating devices are more portable and cost effective, according with the current developing trend. Most importantly, room-temperature operation makes it possible to reduce energy use and risk of gas explosion as well as improve the long-term stability, and this has become ...
