Pressure Sensor for Caterpillar
This 40MPa pressure sensor, cross-referenced as 434-3436, is a hydraulic system component for Caterpillar excavators and heavy machinery.
Overview
This 40MPa pressure sensor is a direct replacement component for hydraulic pressure monitoring in Caterpillar equipment, designed to send accurate pressure readings to the machine's electronic control system. It monitors system pressure to help maintain proper operation and protect against overpressure conditions. This sensor is a critical parts for maintaining reliable hydraulic function on compatible Caterpillar models.
Built For Performance
- Rated for up to 40MPa (400 bar) hydraulic pressure
- High-accuracy sensing element for consistent readings
- Robust housing to withstand vibration and harsh environments
- Standard electrical connector for plug-and-play installation
- Cross-referenced against OEM part number 434-3436
Fits These Machines
- for Caterpillar 311F LRR
- for Caterpillar 329D
- for Caterpillar 349D
- for Caterpillar 326D2 L
- for Caterpillar 324D L
On-The-Job Use
- Monitors hydraulic pump output pressure during digging operations
- Provides pressure data for load-sensing and flow control systems
- Alerts the operator to abnormal pressure conditions that could damage components
- Used during troubleshooting to verify hydraulic system health

Good To Know
Q: Will this sensor work on my Caterpillar 329D? A: Yes, this sensor is designed as a compatible replacement for the OEM part 434-3436, which is used on the models listed including the 329D, but always verify your serial number before ordering.
Q: What happens if the pressure sensor fails? A: A faulty sensor can cause the machine to enter limp mode or display inaccurate pressure readings, leading to poor performance or potential damage. Replacing it with a high-quality sensor restores accurate monitoring.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
