DOC AIRBUS | AMM A320FOIL TEMPERATURE INDICATING SYSTEM - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
** ON A/C NOT FOR ALL
1. General
A. The engine oil system has the indication and warning systems that follow:
- Main oil pressure indicating system
- Low oil pressure indicating system
- Main oil temperature indicating system
- Auxiliary oil pressure indicating system
- Oil level indicating system
- Oil filter differential pressure system
- Oil debris monitoring system.
(1) These systems are used to monitor oil system conditions and signal the flight crew of possible problems.
(2) Components in the indicating systems send a signal to the Electronic Engine Control (EEC), which then sends the signal to the Electronic Centralized Aircraft Monitoring (ECAM) System.

Oil Temperature Indicating System (Temperature Probe)A. Oil Temperature Probe
(1) The oil temperature probe is attached to the front of the OCM on the left side of the main gearbox at approximately the 9 o'clock position.
(a) The oil temperature probe is used to measure the temperature of the scavenge oil that is sent to the oil tank.
(b) The probe is installed on the Oil Control Module (OCM).
(c) The probe measures the scavenge oil temperature in the scavenge oil line through two Resistance Temperature Detectors (RTDs). The RTDs send the temperature signals to both channels A and B of the EEC. The EEC then sends a temperature signal to the ECAM for display on the flight deck.
(d) The oil temperature probe is a line replaceable unit.
