125-9859: 24.5 V pressure transmitter 1259895 pressure sensor

Product Overview

Core Functions

1. Accurate Pressure Monitoring: Built-in high-precision piezoelectric/piezoresistive sensing element, real-time and accurate collection of engine oil pressure and hydraulic system pressure, linearly converts pressure signals into electrical signals, providing continuous and stable working condition data for the ECU, ensuring the equipment is always in a safe pressure range.
2. Intelligent Condition Adjustment: The ECU automatically adjusts parameters such as oil pump output and hydraulic system flow according to the pressure signal fed back by the sensor, optimizing lubrication efficiency and power output, avoiding dry friction damage caused by low oil pressure, and improving equipment reliability and fuel economy.
3. Fault Early Warning & Protection: When the pressure rises/drops abnormally, the sensor sends an early warning signal to the ECU, triggering the dashboard alarm, reminding the driver to stop and overhaul in time to prevent serious faults such as engine cylinder scuffing and hydraulic pipeline bursting, ensuring equipment and personnel safety.
4. Ready-to-Install: 1:1 reproduction of the original factory size, thread specification and electrical interface, fully matching the original mounting position and circuit system of the corresponding Caterpillar models. No modification required, direct replacement of the original part, convenient and efficient maintenance, greatly reducing downtime.
