Ready to ShipHigh-temperature water-level sensors come in various designs and specifications. Each type is best suited for specific industrial applications and environments.
These devices are crucial in managing systems subjected to high heat, such as boilers, petrochemical plants, and power generation facilities.
Hydrostatic Pressure Sensors
These waterproof liquid level sensors measure water depth by monitoring the pressure exerted by the water column above the sensor. They are accurate in determining the pressure, making them useful for deep water applications.
The operating temperature range of these sensors is usually between 100°C and 200°C.
The pressure sensor can be placed at the bottom of a container or vessel, where it is not exposed to high temperature and pressure. Hydrostatic sensors are appropriate for deep tanks and underground water systems.
Capacitive Level Sensors
Capacitive sensors detect the change in capacitance caused by the dielectric variation between the sensor coating and the liquid. Water has a low dielectric constant, making it easily detected by capacitive sensors.
Capacitive sensors can detect levels within 200°C. They are also useful in detecting conductive and non-conductive liquids.
While they may not be as accurate as other types, they are suitable for applications where contact with high-temperature liquids is inevitable.
Ultrasonic Level Sensors
Ultrasonic sensors carry pulses of sound to detect liquid levels. The time it takes for the sound to return after making contact with the water surface is measured.
This time is then converted to level data. These sensors work well in high-temperature environments, up to 200°C, and often used for monitoring in boiling water tanks.
These sensors are mounted outside the tank to avoid contact with the liquid. They are effective in their readings because they use sound waves and do not touch the liquid.
Conductive Level Sensors
Conductive sensors function by completing an internal electrical circuit when the probes are immersed in water. This type of sensor is better suited for detecting water with ions in it. It can easily work in environments with extremely high temperatures, up to 250°C, and high pressure.
Since conductive sensors actually measure the water inside a container and not the water level from outside, they can give effective measurement in small tanks.
They are typically used in the food and beverage and chemical processing industries.
Food and Beverage Industry
High-temperature water-level sensors are useful in food processing and brewing industries where temperature and level control is crucial. These sensors monitor water levels in boilers, sterilizers, pasteurizers, and washing systems.
In these systems, the sensor must withstand high temperature and pressure while maintaining accurate readings for effective system operation.
Chemical Processing
This industry handles hazardous liquids and often operates at high temperatures. High-temperature level sensors measure water levels in reactors, distillation columns, and other equipment.
These sensors are important in this industry because they can survive extreme conditions while maintaining the integrity of chemical processes.
Pharmaceuticals
These sensors are important for sanitation and sterilization in the pharmaceuticals industry. They monitor water levels in sterilizers, autoclaves, and other high-pressure vessels, ensuring correct operation and hardening standards.
Oil and Gas
Monitoring water levels in separators and de-salters is done with high-temperature level sensors in the oil and gas industry. These sensors are designed to survive the harsh environments of high pressures and extreme heat.
They help maintain system safety while providing reliable level measurement in critical applications.
Power Generation
In the power generation industry, high-temperature level sensors are crucial for monitoring water levels in boilers and steam generation systems. These sensors are capable of working under high pressure and temperature in power plants.
This makes it possible for them to provide accurate and durable level measurements.
Metals And Mining
The mining and metals industries also make extensive use of high-temperature level sensors in their operations. In smelting furnaces, molten metal ladles, and tailings impoundments, these sensors detect liquid levels.
Sensors have to tolerate high heat, pressure, and corrosive substances in mining for successful mining operation.
Accuracy
The accuracy of a high-temperature water level sensor is a critical factor in performing its function. Selecting the right sensor for an application involves a thorough understanding of its accuracy.
Consider the acceptable level of error in measuring water level for the application. Ultrasonic sensors are generally more accurate than capacitive or conductive sensors.
Defined accuracy levels are usually found in the manufacturer's documentation. It must also be borne in mind that the accuracy of the sensor will be affected by the conditions where it will be installed.
Working Conditions
The sensor's working conditions must be considered when choosing a high-temperature water level sensor. For example, pressure sensors are best suited for deepwater applications since they measure the pressure of the water column above the sensor.
On the other hand, conductive sensors measure the level of water in small tanks as long as the temperature does not exceed 250°C. Capacitive and ultrasonic sensors are also suitable for high-temperature conditions, which can work up to 200°C.
Material
What a water level gauge is made of is important for its long-term viability, particularly in demanding and high-temperature areas. Sensors in high-temperature settings often contain stainless steel, titanium, and ceramic.
Like the previous point, consider the tank the sensor will be placed in and the liquid inside it. Ensure the sensor is made from compatible materials. This will prevent corrosion, wear, or damage to the sensor functions.
Response Time
It is the period allocated to a sensor for measuring and reporting a change in water level. Fast response is crucial in settings where swift fluctuations in water level occur.
For example, boiler systems in power plants can undergo rapid changes in water levels. Therefore, it is better to choose a sensor with a fast response time in dynamic environments.
Meanwhile, in such stable applications as storage tanks, there may not be any need for fast response.
Compliance & Certifications
Every industry has its own regulations that demand adherence to specific safety and performance standards. Sensors used in regulated industries must meet the standard of these industries.
For the pharmaceuticals industry, its sensors must comply with FDA regulations. Sensors used in food and beverage must comply with hygiene and safety standards like the EHEDG.
Help ensure the sensor meets all required regulations and has the appropriate certifications before purchasing it.
