IV. Features
a. The Radar Level Transmitter uses improved microwave pulse technology
to track any target material from the tip of its antenna to the bottom of the
tank. Its power, pulse widths and sensitivity depend on the distance of the
target from the antenna and the dielectric constant of the reflecting
material.
b. The Radar Level Transmitter sensor features “echo marker” signal
processing, making it among the most technologically advanced pulse
radar system on the market. This technology will provide a reliable
continuous pulse shape unaffected by environmental conditions such as:
c. Simple mounting and push-button calibration make for a very easy
installation. Calibration can be completed on the bench or in the field by
following simple instructions. The sensor can be threaded directly into a 2"
NPT metal or plastic flange. (See Installation section, page 14.)
d. The Radar Level Transmitter offers features such as:
1. Accurate, non-contact measurement
2. Works in conditions where ultrasonic is not acceptable
3. Pulse radar measurement range 10” to 50’
4. Simple push-button calibration
5. Standard 4-20mA signal output
6. Optional RS485 digital output
