Requirements for level measuring devices are diverse, based on their fields of application such as laboratory, mechanical, plant and process technology. Even smart design solutions require suitable sensors. Precision, robustness and speed are crucial in the measured value logging and reliable storage of measured values & documentation. Level Sensors, utilized for determining levels of the free-flowing substances, are imperative in industrial and commercial applications. These sensors are available in a wide range of sizes and are designed through various sensing techniques, as per the requirements.
Industrial and commercial applications expected to drive demand for level sensors
Highly versatile technologies in the level sensors are being introduced by leading manufacturers, improving the precision of devices and eliminating dependency on other huge mechanical measuring devices. Some of the level sensors are foreseen to face challenges during operation in applications of high turbulence or in the steam and foam processes. Although faced with challenges, the market is estimated to witness tremendous opportunities, owing to the introduction of new & advanced emerging technologies in sensors. Level sensors find great importance in the industrial applications. Future Market Insights, in its report, has provided a detailed analysis on the global level sensors market for the forecast period 2017-2027.
Level sensors are used in the nuclear power plants for detecting water levels in cooling circuits. High accuracy is required in the operation of these sensors, as in nuclear power plants even small errors can lead to hazardous outcomes. In automobiles, level sensors are utilised for measuring the level of fuel. Automated coffee machines, refrigerators, water dispensers, and other commercial applications widely use level sensors. Increasing demand for level sensors of high accuracy and precision in commercial as well as industrial applications is expected to drive the growth of the global level sensors market in the near future. In contrast, malfunctioning of level sensors in the applications including high stress, temperature changes, and fluctuating voltage, is expected to restrain the market growth in the upcoming years.
A new submersible probe equipped with a ceramic sensor
Several innovations have been witnessed in the level sensors. One such example is of the separable plastic submersible probe comprising the ceramic sensor. Submersible probes are usually utilised for monitoring river levels, or controlling lock gates. These probes suffer frequently from mussel and algae growth. In case of these probes with stainless steel sensor, cleaning & removal of mussels cause damage to the sensitive diaphragm. However, this new submersible probe is equipped with the robust capacitive ceramic sensor which prevents anything from sticking to it. And even if anything sticks to this sensor, it is easy to remove and clean the sensor without damaging the diaphragm. This sensor is resistant to corrosion caused by water or other aggressive media such as alkaline and acid solutions.
A steel mesh cable sheath providing reliable protection of transmission cables for submersible probes
The separable plastic submersible probe enables high accuracy of around 0.25% FSO, and possesses an outstanding long-term stability. The data measured by submersible probe is transmitted generally to a controller through cables laid in ducts or in ground, extending over several hundred meters. However if these cables get damaged, the effort required in replacing them is expensive and complex. This challenge is been tackled by utilisation of steel mesh cable sheath in this new submersible probe, offering reliable protection. In order to avoid damage by lightning, the probe head has been integrated with an improved surge protection, allowing pulse currents around 8kA to be dissipated.
