A-A-59881, COMMERCIAL ITEM DESCRIPTION: TESTER, EXHAUST GAS TEMPERATURE CIRCUIT (12 JAN 2011)

A-A-59881, COMMERCIAL ITEM DESCRIPTION: TESTER, EXHAUST GAS TEMPERATURE CIRCUIT (12 JAN 2011)., This commercial item description (CID) covers the requirements for a portable, self contained tester that checks thermocouples, thermal switches, and continuous wire fire detection systems. The tester simulates operating conditions of the units under test (UUT). The exhaust gas temperature circuit tester (EGTCT) shall be a user-friendly unit capable of testing the correct operation of thermocouples, thermal switches and continuous wire fire and overheat detection loops. The tester shall be capable of simulating actual operating conditions by supplying a controlled heat to the thermocouples, thermal switches and fire loops. The tester shall be capable of heating probes to an operator controlled temperature and controlling the temperature of the probes using a temperature control function to National Institute of Standards and Testing traceable standards. The tester shall monitor probe temperature and thermocouple output characteristics in order to determine whether the thermocouple is defective. The tester shall test thermal switches by bringing switches to the control temperature and allowing the switch to actuate (open or close) depending on its normal operating position. The tester shall test fire lops by applying a controlled temperature to the loop and monitoring cockpit indications. The EGTCT shall not weigh more than 50 pounds. The preferred configuration will have the main container the approximate size of commercial airline carry-on luggage.
