Pulse radar level sensors track surfaces
Pulse Radar sensors deliver accurate, reliable non-contact level measurement in challenging environmental conditions that can reduce the reliability and accuracy of other types of sensors
Providing the process industry standard output of 4-20mA, the sensors operate using a frequency burst at 6.3 GHz Pulse Radar sensors provide a detection range up to 100 feet (30 m), with a resolution to 0.22 inches (5.7 mm) and accuracy to 1/4% of maximum range

The standard operating temperature range is -40 to 140F (-40 to 60C), with higher temperature ranges available on special order.
"The primary advantage of the APG Pulse Radar sensors is the unique self-adjusting-signal and target-tracking technology.
This technology enables the sensor to automatically keep the signal at an optimal level to maintain and track the target throughout the measuring range, and under a variety of target conditions," says Jon Cox, Automation Products Group Product Manager.
Pulse Radar sensors will operate over long distances even with target materials that have moderately low dielectric constants.
The sensor automatically adjusts the transmit power and receiver gain to optimise the return signal to a level that delivers accurate readings, and is not affected by any interference.
The sensor is designed to overcome potential build-up on the antenna, and avoids obstacles that may be installed near the detection path.
They also offer reliable operation in metal stilling wells.
Programmable software allows users to mask unwanted echoes and adjustable damping factors.
"Because Pulse Radar sensors use electromagnetic waves rather than sound waves, they are an ideal level sensing solution in applications with excessive foam.
Electromagnetic waves are also unaffected by heavy fumes or vapour layers that can reflect ultrasonic signals, resulting in false readings.
Additionally, highly corrosive or acidic materials can attack and break down the bonds inside an ultrasonic transducer, and because radar waves are transmitted through an antenna of solid material, Pulse Radar sensors are unaffected by such media," says Cox.
Powerful electromagnetic waves also enable Pulse Radar sensors to shine in vacuum environments, as well as applications with rapid temperature changes, high temperatures and high acoustical noise, and those with long measuring ranges.
