P-1 (P-1Tr)

P-1 (P-1Tr) System Overview

The P-1 (P-1Tr) is an aircraft temperature receiver designed to measure outside air temperature and provide corresponding electrical signals for engine operating mode measurement systems.

P-1 (P-1Tr) Measurement Function

The receiver converts temperature values into resistance changes transmitted to the receiving instrument, enabling temperature correction of engine operating parameters and ensuring accurate indication under varying environmental and flight conditions.

P-1 (P-1Tr) Aircraft Application

The unit is used as part of IR-117 and IR-117M engine operating mode indication systems on aircraft and helicopters equipped with corresponding engine monitoring equipment.

P-1 (P-1Tr) System Integration

The receiver is designed for continuous operation with stable measurement characteristics and short thermal response time, operating with limited measuring current and installed according to aircraft system configuration. The product is also known under alternative designations P-1 and P-1Tr.
