Description
The 274‑6719 Pressure Sensor is a Caterpillar OEM component built for the rigors of industrial and off‑highway applications. Featuring a durable brass-alloy body and standard 3-pin connector, it accurately detects oil pressure up to 1,135 kPa. It outputs a proportional analog or PWM signal based on sensed pressure.
Engineered for harsh environments, this sensor resists vibration, temperature extremes, and contaminants. It’s widely employed in Cat engines such as the 3406E, 3412, 3516, C15, and C175, and is a critical part of systems including engine oil monitoring, HVAC modules, and auxiliary pump pressure management. OEM and reliable aftermarket replacements ensure system accuracy and engine protection.
