Monitoring points can also be pinpointed on every meter. 🎯 Features of Optical Fiber Sensing in DTSX System: ✅ Power supply not required, explosion-proof, not affected by electromagnetic noise; ✅ Monitoring distance: up to 50 km; ✅ Monitoring temperature: -200 to 300 °C; ✅ Shortest monitoring cycle: Approx. 5 seconds; ✅ Temperature resolution: 0.03°C; ✅ 24 hours / 12 months / 365 days, temperature monitoring. #engineering #environment #mining #refinery

Measuring temperature by optical fiber Distributed temperature sensing (DTS) measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element. Unlike traditional electrical temperature measurement (thermocouples & RTD), the length of the fiber optic cable is the temperature sensor. Distributed temperature sensing can provide thousands of accurate and precise temperature measurements over a long distance. Compared to traditional electrical temperature measurements, distributed temperature sensing represents a cost effective method for obtaining accurate and high resolution temperature measurement. Yokogawa DTSX1 measures temperature and distance over the length of an optical fiber using the Raman scatter principle.

EPOXY TYPE NKI NOISE IMMUNE Thermometrics Epoxy-Coated Type NKI of Noise Immune Thermistors are newly developed, consisting of a noise immune NTC thermistor with an integrated radio frequency (RF) decoupling function, providing protection from electromagnetic interference (EMI) at the component level over a wide frequency range.   With increasing complexity of electric systems and density of electronic components in modern vehicles, conventional NTC thermistor sensors are vulnerable to stray electromagnetic interference causing self-heating. Conventional mitigation strategies include: * Using cable screening * Adding ferrite cores * Incorporating twisted-pair wiring * Employing specialized cable routing While these solutions can be beneficial in some cases, they can also result in an increase in the cost, weight, or complexity. The NKI thermistor eliminates the need for conventional mitigation strategies. These sensors also have applications in monitoring plumbing and reservoir leaks, burst water pipe surveillance, data center and downhole tools. #amphenol #nki #noiseimmune #emi #thermistor #downholetools #datacenter #ev

The fluorescent optical fiber temperature sensor is a new type of temperature measurement sensor, which consists of two parts: a photoelectric conversion module and a temperature measuring optical fiber;the temperature-sensing part at the end of the optical fiber is connected to the photoelectric conversion module through the ST connector, without electrical connection, and is not affected by strong electromagnetic interference, which solves the problem that high-voltage equipment cannot measure temperature;it is an independent temperature measurement system, with single-point temperature measurement, DC5V power supply, and UART communication, which can be connected to instruments as an independent sensor.#Fiberoptictemperaturemeasurement #Fiberopticsensor #Temperaturesensor #Fiberoptictemperaturesensor #Transformertemperaturemeasurement

Performance Estimation of In-Vessel Resonant Communications Measurements of pertinent parameters of liquids such as temperature, density or viscosity within large, enclosed vessels, such as barrels, cisterns or tanks is an important practical task to control technological process or storage conditions. This type of measurements requires the establishment of reliable wireless communication between multiple sensors, preferably, but not necessarily uniformly distributed within the enclosed vessel. However, this is a challenging task since the applicability of the existing traditional communication methods is performance limited in the scenario of enclosed vessels filled with high-loss liquids.

In this article, we explore two different methods for analyzing the impedance transformation ratio of a transmission line transformer. https://bit.ly/4cIRhvx
