The model number covered by this report is BM702. This report is designed to demonstrate the compliance of this device with the requirements outlined in Part 90 of CFR 47 using the methods outlined in Part 2 of CFR 47. The current revision date, October 1,1998, of each Part has been used for technical requirements. The confidential information and descriptions included in this application are detailed descriptions of the products, block diagrams, component specifications, and schematic diagrams. We hereby respectfully request under the provision of section 0.457d of the code that the documents listed below be held confidential. Technical Descriptions and Block Diagrams Schematics Bill of Materials Krohne America, Inc. is requesting that the Technical Descriptions, Block Diagrams, Schematics and Bill of Materials be kept confidential in the FCC application because of the proprietary design developed by Krohne America, Inc. that is unique to the industry. _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 4 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 Product Description The BM 702 level gauge is designed solely for measuring the level, distance, volume and reflection of liquids, pastes, slurries, particulate materials and solids. Five different antennas are available for use with the unit depending on the application. There are four horn antennas and one Wave-Stick antenna. The Wave-Stack antenna has several different part numbers which correspond to the different lengths of waveguide that lead to the radiating potion of the WaveStick. We tested the 6in Wave-Stick. Unit Tested Model Number: BM702 Serial Number: 0/311883.001 Antennas: 3in horn 2116340100 4in horn 2113010100 6in horn 2113000100 8in horn 2112540100 Wave-Stick 3159860600 Related Submittal(s) Grants There are no other approvals required for this device. _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 5 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 Test Methodology Radiated emission testing was performed according to the procedures in ANSI C63.4 (1992). Radiated testing was performed at an antenna to EUT distance of 3 meters below 1 GHz, and at a distance of 3 or 1 meter(s) above 1 GHz. The actual test distance used is noted in the test data sheets. The device’s performance was investigated to 40GHz. The EUT was powered by a DC power supply for all tests. All other performance tests were made in accordance with the procedures outlined in Part 90 of CFR 47. Each of the antennas was investigated at the fundamental frequency to determine which was the most efficient radiator – this was the 8in horn antenna. Using the 8in horn antenna, harmonics and spurious emissions were checked from 7 – 40GHz. Test Facility Curtis-Straus LLC All testing for the range 30–40000MHz was performed at Curtis-Straus (A2LA Certificate Number: 1627-01). The open area test site used to collect the radiated data is located at 527 Great Road, Littleton, MA 01460. Site “M” was used. _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 6 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 7 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 Equivalent Radiated Power Conducted measurements of the transmitter output were not possible, since the horn antenna is permanently affixed. Therefore field strength measurements with a horn antenna were done instead. The following is the calculation of the limit in field strength based on the limit in power. ERP = Equivalent Radiated Power PD = Power Density V = Volts Fundamental Maximum Measured Output =117.7dBµV/m = 0.767V/m @ 1m PD = (V/m)^2/(resistance of free space [Ω]) PD = 0.7672/377 PD = 0.00156W/m2 ERP = 4πPD*R2 ERP = 4π(0.00156)*12 ERP = 19.6mW = 0.0196W = Pfund Emissions 250% or more outside the fundamental should be attenuated by at least: 43dB + 10 log Pfund 25.9dB To calculate the limit of the harmonics: E = 5.5/(distance) x SQRT(Ptot) - Formula for E-field from isotropic antenna Ptot = 19.6mW – 25.9dB = 12.92dBm – 25.9dB = -13dBm = -43dBW Ptot = 0.00005W E1m = (5.5/1) * SQRT (0.00005) E1m = 0.039V/m = -28.1dBV/m = 91.8dBµV/m E1m = 91.8 dBµ µV/m Therefore the limit in field strength at 250% outside of the authorized bandwidth is as follows: E1m = 91.8 dBµ µV/m _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 8 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 Test Equipment Used SPECTRUM ANALYZERS Analyzer WHITE 9kHz-22GHz GREEN 9kHz-26.5GHz BLACK 9kHz-12.8GHz ORANGE 9kHz-26.5GHz Model No. Company Serial No. Calibration Due 8593E HP 3547U01252 24-APR-2001 8593E HP 3829A03618 04-OCT-2000 8596E HP 3710A00944 28-JUN-2001 E4407B HP US39440975 05-MAY-2001 LISNS LISN YELLOW-BLACK 9kHz-30MHz Model No. Company Serial No. Calibration Due 8012-50-R-24-BNC Solar 984735 26-OCT-2000 OPEN AREA TEST SITES (OATS) Site “F” Florida “M” Maine FCC Code IC Code VCCI Code Calibration Due 93448 IC 2762-F R-468/ C-480 28-JUN-2001 93448 IC 2762-M R-904/ C-480 22-MAY-2001 Model No. Company Serial No. Calibration Due CBL6112B Chase 2412 23-JUN-2001 3115 EMCO 9703-5148 31-MAY-2001 3160-09 EMCO 9610-1068 10-MAY-2001 ANTENNAS Antenna GREEN-BLACK Bilog: 30MHz-2GHz BLACK Horn: 1-18GHz WHITE Std Gain Horn: 18-26.5GHz HARMONIC MIXER Mixer Model No. Company Serial No. Calibration Due HARMONIC MIXER 11970A HP 2332A00900 24-MAY-2001 26.5-40 GHZ _____________________________________________________________ Curtis-Straus LLC • 527 Great Road • Littleton, MA • TEL (978) 486-8880 • FAX (978) 486-8828 Page 9 of 14 FCC Application for Krohne America, Inc. •FCC ID: JH5BM702 • Report No. EA0897-1 ______________________________________________________________________________ 11-Oct-00 PREAMPLIFIERS Preamplifier WHITE 1-20GHz BLACK 0.01-2000MHz YELLOW-BLACK 1-20GHZ YELLOW 18-26.5GHz Model No. Company Serial No. Calibration Due SMC-12A MITEQ 426643 09-OCT-2001 n/a 01-MAR-2001 ZFL-1000-LN MiniCircuits/ C-S SMC-12A MITEQ 535055 17-OCT-2000 AFS4-1800265060-8P-4 MITEQ 467559 28-AUG-2001 Model No. Company Serial No. Calibration Due TH300 Dickson 9044101 27-MAR-2001 BA928 Oregon Scientific C3166-1 21-AUG-2001 METEOROLOGICAL METERS Meter TEMPERATURE /HUMIDITY GAUGE ATMOSPHERIC PRESSURE GAUGE TRACEABLE CLOCKS Clock Model No. Company Serial No. Calibration Due 5003 5003 Control Company 99026940 16-NOV-2000 Unless otherwise noted the calibration interval is one year.
