Product Description

Product Description

E+H FDU93

In the ever - evolving landscape of industrial measurement technology, Endress+Hauser's E+H FDU93 ultrasonic sensor has emerged as a highly reliable and advanced solution. This sensor is designed to meet the diverse and complex requirements of a wide range of industries, offering accurate and efficient measurement capabilities. The FDU93 is part of Endress+Hauser's Prosonic S series, which is renowned for its high - performance ultrasonic sensors. With its innovative design and state - of - the - art technology, the FDU93 has become a popular choice for applications where precise level and flow measurements are crucial.
The FDU93 is extremely effective in measuring the level of liquids across various industrial settings. It can be deployed in large storage tanks, where it accurately determines the volume of liquids such as water, chemicals, and fuels. In the oil and gas industry, for example, it is used to measure the level of crude oil in storage tanks, ensuring proper inventory management. In chemical plants, it can measure the level of highly corrosive liquids. Its non - contact measurement principle makes it ideal for such applications as it does not come into direct contact with the liquid, preventing any corrosion - related issues. The maximum measuring range for liquids is an impressive 25 m (82 ft), which is suitable for large - scale industrial storage and processing facilities.

1. Technical Specifications

1.1 Measuring Principle
The FDU93 operates based on the ultrasonic time - of - flight principle. It emits high - frequency ultrasonic pulses from its sensor head. These pulses travel through the air (or the medium in which the measurement is taking place) towards the surface of the material being measured. When the pulses hit the surface, they are reflected back to the sensor. The sensor then measures the time it takes for the pulse to travel to the surface and return. Since the speed of sound in the medium is known, the distance to the surface can be calculated using the formula: distance = (speed of sound × time - of - flight)/2. This principle enables highly accurate and non - contact measurements, making the FDU93 suitable for a wide range of applications.
1.2 Accuracy
The accuracy of the FDU93 is specified as ±2 mm + 0.17% of the measured distance. This high level of accuracy is crucial in industries where precise measurements are essential for process control and product quality. In a pharmaceutical manufacturing plant, for example, accurate level measurement of raw materials in storage vessels is necessary to ensure the correct formulation of drugs. The integrated temperature sensor in the FDU93 plays a vital role in maintaining this accuracy. It compensates for changes in the speed of sound due to temperature variations in the medium, ensuring that the time - of - flight calculations remain accurate.
1.3 Process Temperature and Pressure
1.3.1 Temperature
The FDU93 can operate in a wide process temperature range of - 40 °C... 80 °C (- 40 °F... 176 °F). This makes it suitable for use in both cold storage applications, such as in the food and beverage industry for measuring the level of products in refrigerated tanks, and in high - temperature processes, such as in chemical plants where there may be hot reaction vessels.
1.3.2 Pressure
The process pressure range for the FDU93 is 0.7 bar... 4 bar abs (10 psi... 58 psi). It can function effectively in both low - pressure and moderately high - pressure environments. In a water treatment plant, it can be used in pipelines and tanks with different pressure levels, from the low - pressure influent lines to the higher - pressure effluent lines. The sensor is designed to be pressure - resistant, ensuring its proper operation and long - term reliability in these pressure conditions.

 2. Features

2.1 Integrated Temperature Sensor for Time - of - Flight Correction
The integrated temperature sensor in the FDU93 is a key feature that significantly contributes to its high accuracy. The speed of sound in a medium is highly dependent on temperature. As the temperature changes, the time it takes for the ultrasonic pulse to travel to the target and back will also change. The temperature sensor continuously monitors the temperature of the medium. The measured temperature is then used to adjust the time - of - flight calculation. For instance, if the temperature in a storage tank increases, the speed of sound in the air (or other medium) inside the tank will increase. The sensor's electronics will automatically compensate for this by adjusting the time - of - flight value, ensuring that the calculated distance remains accurate. 
2.2 Hermetically Welded PVDF Sensor
The hermetically welded PVDF sensor of the FDU93 offers several advantages. Firstly, the hermetic welding ensures a tight seal, preventing any ingress of moisture, dust, or other contaminants into the sensor. This is of utmost importance for maintaining the sensor's performance and reliability, especially in harsh industrial environments. Secondly, PVDF is a material with excellent chemical resistance. It can withstand exposure to a wide range of chemicals, including acids, alkalis, and solvents. In industries such as chemical processing, petrochemicals, and pharmaceuticals, where corrosive substances are commonly handled, the PVDF sensor can operate for long periods without being damaged by chemical attack. This not only reduces the need for frequent sensor replacements but also ensures the integrity of the measurement system.
2.3 Separate Installation from the Transmitter
The FDU93 can be installed up to 300 m away from the transmitter. This separate installation feature provides greater flexibility in system design and installation. In large industrial plants, where the sensor may need to be placed in a difficult - to - reach location, such as the top of a tall silo or in a remote part of a wastewater treatment lagoon, the transmitter can be installed in a more accessible location, such as a control room or a central instrumentation cabinet. This makes it easier for maintenance and calibration purposes.
