Temperature Sensors, Thermowells, and Response Times

· Thermowells protect temperature sensors from harsh media. On the downside, these fittings increase the thermal response time. Therefore, knowing precisely what that response time is becomes a key factor in controlling processes and systems. Figure 1: The measured temperature (red curve) always lags behind the actual temperature (blue curve). In the real world, not even the best …

CHAPTER 6: CHEMICAL SENSORS | Expanding the Vision of ...

Recalling the definition of an ideal chemical sensor, the requirements of portability, ease of fabrication, and low cost would seem to be incompatible with a sensor requiring a preceding separation step or a complex detector like a mass spectrometer. However, inadequately explored research avenues offer the potential for chromatographic and electrophoretic instruments that are simple ...

Sensors Overview | Android Developers

· Sensors that use the on-change or one-shot reporting modes don't receive events. Given these restrictions, it's best to detect sensor events either when your app is in the foreground or as part of a foreground service. Unregister sensor listeners. Be sure to unregister a sensor's listener when you are done using the sensor or when the sensor activity pauses. If a sensor listener is registered ...

The Defining Series: Mud Logging | Schlumberger

· Gas is separated from the mud, and a suction line siphons the gas to the mud logging unit for analysis. Cuttings are sampled at the shaker screen and examined inside the unit. When these evaluations are combined with drilling parameters—drill rate, pump rate, pump pressure, weight on bit, mud properties and other inputs—the mud logger can identify potential pay zones and ascertain how …

Lower and Upper Explosive Limits for Flammable Gases and ...

This flame arrestor is necessary to prevent the sensor itself from starting a fire and does not prevent gases like methane, propane and ethane from reaching the Wheatstone bridge. However, hydrocarbons like gasoline, diesel, solvents, etc, diffuse through the flame arrestor slower so that less vapor reaches the Wheatstone bridge and the sensor gives less output.

LogiDataTech - Gassensor & Messprinzipien

The gas sensor is a sensing device able to measure target gas molecules in a given environment. The gas sensor starts working when gas molecules encounter the sensor's solid receptors and cause a potential difference that is converted into an electrical signal [160].

What is an Ultrasonic Sensor? | FierceElectronics

· Ultrasonic sensors are also used in robotic obstacle detection systems, as well as manufacturing technology. In comparison to infrared (IR) sensors in proximity sensing applications, ultrasonic sensors are not as susceptible to interference of smoke, gas, and other airborne particles (though the physical components are still affected by variables such as heat).

Understanding What’s Meant by “Intrinsically Safe”

· Understanding What’s Meant by “Intrinsically Safe”. Fire is a hazard in many industries. Sometimes the risk is quite evident, as when flammable gasses like hydrogen and propane are being produced or handled, but in other situations it is less obvious. In particular, dust can often be highly combustible. A fire needs fuel, oxygen and an ...

Remote Sensors | Earthdata

· Remote sensing instruments are of two primary types: Active sensors, provide their own source of energy to illuminate the objects they observe. An active sensor emits radiation in the direction of the target to be investigated. The sensor then detects and measures the radiation that is reflected or backscattered from the target.
