17 57-603 horizon guided wave radar transmitter 3.0 reference information this section presents an overview of operating the horizon guided wave radar level transmitter as well as informa- tion on troubleshooting common problems, listings of agency approvals, lists of replacement parts, and detailed physical, functional, and performance specifications. 3.1 description horizon is a loop-powered two-wire, 24 vdc, level trans- mitter based on the concept of guided wave radar. guided wave radar (gwr) is a relatively new level mea- surement technology. the horizon electronics are housed in a single compart- ment housing available in either cast aluminum or valox. 3.2 theory of operation 3.2.1 micropower impulse radar gwr combines tdr (time domain reflectometry), ets (equivalent time sampling) and modern low power circuitry. this synthesis of technologies brings to the level market a high-speed radar circuit (speed of light transmis- sion) at a small fraction of the cost of conventional radar. the electromagnetic pulses are propagated via a waveguide that yields a system many times more efficient than through-air radar. a small amount of energy continues down the probe in a low dielectric fluid, e.g. hydrocarbon air r = 1 media r > 1.7 24 vdc, 4-20 ma loop powered a reflection is developed off the liquid surface transmit pulse hart version hcf release date compatible with 704 software dev v1 dd v1 january 2003 version 1.0a and later 2.7.4 hart revision table (model 704)
18 57-603 horizon guided wave radar transmitter 3.2.2 time domain reflectometry (tdr) tdr uses pulses of electromagnetic (em) energy to mea- sure distances or levels. when a pulse reaches a dielectric discontinuity (created by media surface), part of the energy is reflected. the greater the dielectric difference, the greater the amplitude (strength) of the reflection. although tdr is relatively new to the industrial level measurement industry, it has been used in the telephone, computer, and power transmission industries for years. in these industries, it is used to successfully find wire or cable breaks and shorts. an em pulse is sent through the wire traveling unimpeded until it finds a line break or short. a reflection is then returned from the break and a timing circuit pinpoints the location. in the horizon transmitter, a waveguide with a character- istic impedance in air is used as a probe. when part of the probe is immersed in a material other than air, there is lower impedance due to the increase in the dielectric. when the em pulse is sent down the probe and meets the dielectric discontinuity, a reflection is generated. 3.2.3 equivalent time sampling (ets) ets is used to measure the high speed, low power em energy. ets is a critical key in the application of tdr to vessel level measurement technology. the high speed em energy (1000 ft/s) is difficult to measure over short distances and at the resolution required in the process industry. ets captures the em signals in real time (nanoseconds) and reconstructs them in equivalent time (milliseconds), which is much easier to measure with todays technology. ets is accomplished by scanning the waveguide to collect thousands of samples. approximately 8 scans are taken per second. 3.3 troubleshooting the horizon transmitter is designed and engineered for trouble-free operation over a wide range of operating conditions. common transmitter problems are discussed in terms of their symptoms and recommended corrective actions. information on how to handle material buildup on the probe is also provided in this section. warning! explosion hazard. do not connect or disconnect equip- ment unless power has been switched off or the area is known to be non-hazardous.
