BH112JD-80 JETCAL®1 Analyzer The BH112JD-80 increases engine testing capabilities to help operators keep pace with the increasing complexity of today's turbine engines. The microprocessor-based unit incorporates the following functions: • Enables dynamic and static testing of engine speeds, _ temperature, fuel flow and pressures . " i • Obtains ambient temperature at the aircraft III • Obtains ambient pressure at the aircraft ^ I • Measures frequencies from monopole pick-up • Measures up to 3 speeds • Accepts pre-programmed parameters for 10 engines • Software calibrated ' • Stores engine and aircraft I.D. data • Prints out run data sSES? TK Components The BH112JD-80 JETCAL® Analyzer consists of three sections: • Data Acquisition Unit (DAU) • Probe Control Unit _T--..A' • Accessory/Heater Probe Case An operator can program the Data Acquisition Unit (DAU) with the appropriate frequency and pressure calibrations required to ^ test 10 selectable engine types. Test results may then be printed ,.J] immediately using the printer installed in the unit. The portability of the DAU allows operation on the flight line or in the cockpit with test cell accuracy. The probe control unit contains the power supply and the control required for heater probe operation when testing engine thermocouples. The probe control section is used with the DAU module to control the heater probe temperature, as well as the temperate of the engine thermocouple harness. The accessory case provides storage space for the cables and other accessories required for engine testing. 1 JETCAL® is a registered trademark of Howell Instruments, Inc. .^8945 South Freeway Fort Worth, Texas 76140 www.howellinst.com 817-336-7411 Fax: 817-336-7874 info@howellinst.com

BH112JD-80 JETCAL® Analyzer Temperature Under normal conditions, the BH112JD-80 measures and displays the temperature output of the engine's Chromel®-Alumel®2 thermocouple harness. In addition, the unit can measure and display an auxiliary Chromel®-Alumel® temperature (AUX TEMP) input as well as ambient temperature (TAMB) from a Howell-supplied ambient temperature sensor. The unit can also display the temperature setting of the heater probes. Temperatures can be displayed in either °C or °F. Pressure A pressure transducer is mounted inside the BH112JD-80 that allows ambient pressure...
