The global demand for float switch sensors experienced a minor slowdown in the pandemic in 2020 due to shut-down of production hubs and other trade barriers. However the situation is getting stabilized in 2021 and the manufacturers are bringing updated products and services to catch global attention.In 2021, rising usage in process industries along with the use of IoT solutions is likely to add faster progress in the forthcoming years. Healthcare, aerospace, defense, construction and mining industries are among the industrial sectors highly opting for such level sensors.
Leading vendors like Ametek Corporation, Vega Corporation, Madison, Savolite, Deeter Electronics, Hamilton Electronics and SMD Fluid Controls are spending in research and development projects and technological advancements to bring innovation for attracting customers in 2021.
For instance, Ametek Corporation introduced ‘Model 575’, a submersible level transmitter on August 2020. It is a hydrostatic product for quick andreliable level measurement suitable for different level monitoring needs including lift stations, inventory tank measurements, ponds, lakes, rivers, landfills, reservoirs or other kind of water treatment facility including power plants, steel mills, mines, refineries, municipal water and wastewater treatment facilities.
The model indicates the measurement level by continuously measuring hydrostatic level pressure via its sensing element and transmitted by a 4-20 mA signal. This design is providing excellent linearity and repeatability, low hysteresis and long term stability to the users in 2021.
In addition to that, Emerson Corporation introduced a series of Rosemount Solid Level switches on 30th January, 2020 to optimize operations, provide point-level monitoring and support overfill prevention. It is based on four technologies enabling Emersion to offer a product portfolio for continuous and point level solids measurement. Vibrating fork, paddle, capacitance and vibrating rod switches within the rosemount range ensures monitoring of solid materials such as powders, grains and pellets in all silo types across industries including food and beverage, chemical, power, cement, mining and plastics industries.
he switches require low levels of maintenance and are designed for operation in challenging environments including those with high pressures, dust and risk of explosion. Rosemount 2511 and 2521 vibrating fork switches provide solutions in applications involving light, fine-grained and powedered materials where measurement sensitivity is required whereas rosemount 2501 rotary paddle switch can be used as a full, demand or empty detector in storage silos or process vessels. The switch is ideal for use with materials that have dielectric values as low as 1.5 and prevents material build-up where there is risk of coating.
What are Float Switch Sensors?
Float switch sensors, equipped with reed switch technology, provide accurate measure of liquid level height in containers. To comply with the dimensions of the containers, float switch sensors come up with field-adjustable stem lengths, eliminating the need to employ multiple sensors. Furthermore, float switch sensors, such as ultrasonic sensors, are highly suitable in the areas where monitoring of every intermediate level of containers is paramount.
Additional incorporation of side mount in float switch sensors is finding its use in compact settings. The magnet located in the system actuates the reed contact after reaching a specified level. Side mounts in float switch sensors are made up of teflon to enable operation in high-viscosity or contaminated liquids. Float switch sensors ensure better durability by housing the switch, thereby preventing it from direct contact with the liquid.
The floating switches in float switch sensors confine their operation to chemical environments where industrial mixers or agitators are absent, while their rigid cousins can be employed in extreme levels of the tank to avoid damages due to industrial mixers. Availability of two mounting options allow reversible switching function, making the installation straightforward and cost-efficient. Furthermore, reduced water and power consumption of float switch sensors are set to be the goldmines of growth.
Reliability and flexibility in detecting level of liquid such as oil within a container or a tank has remained instrumental in driving the adoption of float switch sensors, in a bid to enhance quality of the respective application they are used in. For instance, the food and beverage manufacturing has always been under pressure to deliver products to meet consumer requirement and pass inspections of concerned authorities.
Float switch sensor plays a vital role in maintaining liquid level in tanks to avoid improper formulation and overflow, thereby keeping the ingredients at suitable temperatures during the production process. In addition, float switch sensor being a cost efficient solution, it has witnessed significant proliferation across industrial applications including oil and gas, chemical processing and water treatment plants, to name a few.
Furthermore, the use of float switch sensor in determining level of diesel liquids or coolants is likely to grow with increase in the production of passenger cars and commercial vehicles and expanding automotive aftermarket. However, with growing technological advancements, companies have developed optical sensors, a relatively high-priced solution, that have high efficiency in detecting fluid levels. Introduction of optical sensors are likely to impede the adoption and sales of float switch sensors, in turn restricting the growth of the float switch sensor market.
