Here at Automation Products Group, Inc. (APG), we are thrilled to introduce our new TRUE ECHO® CR-L radar level sensor. Discover how this cutting-edge device stands out with its advanced features and see how it compares to our other exceptional products.
Why Choose Radar Level Sensors?
Radar sensors use electromagnetic waves, which travel much faster than sound waves. This non-contact measurement method allows radar sensors to efficiently measure viscous materials, vapors, liquids, sludges, slurries, and dense materials. In contrast, ultrasonics use sound waves to measure, but these slower waves can become disrupted as they bounce off the target, which can lead to less reliable measurements.
What is a Radar Level Sensor?
Radar sensors emit low-energy, high-frequency electromagnetic impulses, generated by the sensor’s circuitry. When the electromagnetic waves hit the surface of the substance, part of the impulse energy is reflected back to the sensor. The sensor then calculates the level based on the time difference between the impulses sent and the impulses reflected.
Excelling in Tough Conditions
TRUE ECHO technology is designed to withstand challenging conditions. It remains unaffected by temperature thanks to the dynamic sensing technology programmed in our TRUE ECHO radar sensors.
The Performance Drivers of the TRUE ECHO CR-L Radar
The TRUE ECHO CR-L is a Frequency Modulated Continuous Wave (FMCW) radar, bringing the high accuracy of radar sensors to industrial liquid measurement. Unlike pulse radar sensors, FMCW radars emits a continuous signal, allowing for more precise measurements.
Experience the Advantages of the Radar
Here are some key benefits of the TRUE ECHO CR-L radar sensor:
- Temperature Resilience: Unlike ultrasonic sensors, the TRUE ECHO CR-L is less affected by temperature variations, making it ideal for many applications.
- Ease of Setup: With easy-to-follow instructions, the radar is ready to go in no time.
- High Accuracy: The continuous signal emission of FMCW radar technology ensures precise and reliable measurements.
