The RangeFinder MWS-10RF FMCW level sensor offers the latest in microwave sensor engineering in relation to radar distance measurement under the most extreme conditions. Utilizing all the latest advances in technology, it is quite literally the most advanced of its kind, in the world.
Using the FM-CW measurement method, combined with circular polarized [rotary] microwaves, high performance components, fast intelligent signal processing and high tech user friendly mWave Software a highly accurate, extremely stable and reliable level measurement is achieved under the most adverse of circumstances.
Features:
1. Unaffected by Adverse Conditions
The antenna can be installed in the high temperature zone without the need of additional cooling devices.
The antenna and controller are easily connected by bent and straight waveguide tubing.
Microwaves are unaffected by temperature, flames, vapor, airborne particles or dirt.
Designed for iron and steel industry conditions.
2. Hccuracy and Reliability
Error less than 10mm.
False measurements caused by double-reflected waves are eliminated through the use of circular polarized [rotary] microwaves.
The accuracy of the measured range is not affected by fluctuating temperatures nor does it deteriorate over extended periods.
Utilizes filters which eliminate spurious signals.
3. The Operational State is Shown on your Personal Computer
The mWave™ displays the FFT spectrum, the received signal and various preset values.
The received signal, FFT spectrum and the trend measurement are continuously displayed. This displayed data can be recorded and reviewed in real or accelerated time.
Use of the recording and reviewing capabilities allows the system parameters to be optimized off-line and allows for remote troubleshooting/assistance.
The display indicates and outputs the internal temperature and any abnormal conditions (i.e. low received signal power, rising temperature in the controller and communication failures).
4. Convenient Built in Functions
A reference point and the required dynamic range are easily preset.
Compatible for use with a personal computer.
Automatic power supply 90˜240V, 50/60Hz.
Communicates with computer by RS-232C.
4-20mA, analogue output.
RS-422 digital output and input terminals allow remote communication via LAN/ETHERNET.
5. Lightweight and Compact
Portable. (7.5kg controller only)
Easy installation.
6. High Adaptability
Both hardware and software can be modified to suit your requirements |

Semrad-Microtrek
The Microtrek level gauge operates on the well known TDR (Time domain Reflectometry) which is commonly used as test system for underground cables i.e. if there is an open circuit or a leakage to ground the TDR technology will pin point the location of the failed cable. This technology has been enhanced to measure the level of Bulk solids and Liquids in vessels, bins and silos.
This two-wire level transmitter sends Micropulses along a cable or rod at the velocity of light. As soon as the pulse reaches the product surface, it reflects back to the electronics. Since the velocity of light is constant in Air or Gases, the Microtrek does not require any calibration or maintenance. Distance is directly proportional to the Time of Flight of the pulse divided by 2.
The Microtrek can be used to measure liquids and bulk solids in Steel/Fiberglass Vessels, Bins and Silos. The simple installation and the 2 wire electrical connection make the Microtrek one of the most popular level instruments on the market. Used on liquids and bulksolids the Microtrek can measure the level of very fine Oils, Aggressive Chemicals, Acids, Polymers, Alumina, Cement, Flyash, and Grain with far superior results over Ultrasonics and Non Contact Radar. With HART communications as standard on the 4-20ma output the Microtrek is a very versatile level transmitter.

DIY - Fitting a Water Tank Contents Gauge
It is quite hard to "guesstimate" how much water is in the tank in your A'liner. First up you have to peer under the bed - no easy task for those with the sofa bed model who leave the bed made up. Even if you can look underneath it's still very hard to "guess" the level. Bearing all this in mind we lashed out and bought a water level gauge - 100% Australian made by RV Electronics. This works fantastically well and installation is fairly straight forward taking about 2 hours. Essentially an arm is inserted into your tank and sealed with a special rubber compression fitting and a cable runs to the gauge part. It uses its own built in battery. To find out how much water you have left, you simply press the TEST button. If there's four buckets left you get four green lights. If there's two buckets left you get two green lights as long as you use the same hole position as we did in your tank. Cooool stuff and great for making other A'vanners jealous, as you normally only find these devices fitted on $30,000.00+ caravans and motorhomes! This gadget has its own built in lithium battery and it should last at least two years, as long as you can keep your inquisitive grand children away from it! What is it with kids and water?

Microwaves and RF
Welcome - Microwave design articles, applications, and high-frequency design techniques for microwave and wireless engineer. Switching systems are vital parts of automated-test-equipment (ATE) systems for evaluating communications components. Since a typical test system must route a wide range of signals, including RF, microwave, and DC bias signals, to a wide range of instruments (including network and spectrum analyzers and power meters), a switching system must perform reliably, accurately, and efficiently in support of a high-throughput ATE system. Properly configuring an RF/microwave switching system can improve the performance of an ATE system as a whole.
