Komatsu High Pressure Sensor PC200-8 PC300-8 PC400-8 7861-93-1812

Product Specification

7861-93-1812/7861-93-1812 for Komatsu PC200-8 PC300-8 PC400-8 high pressure sensor

product details:

The measurement range of the pressure sensor is 0~100MPa, the range ratio is 10:1, and the accuracy is 1% FS. What is the error when the range is 0~100MPa and 0~50MPa respectively?

The basic errors of 0~100MPa and 0~50MPa are both ±1MPA, but the percentage accuracy errors are 1% and 2% respectively, which is the same as the increase in the range ratio, so the selected range of the sensor may be close to the actual measurement range. , preferably about 70% of the commonly used range


Komatsu pressure sensor:

Komatsu Pressure Sensor When oil enters from the pressure inlet and pressure is applied to the diaphragm of the oil pressure detector, the diaphragm bends and deforms. The measurement layer is installed on the opposite side of the diaphragm, and the resistance value of the measurement layer changes, so that the curvature of the diaphragm becomes the output voltage, and the output voltage is transmitted to the voltage amplifier, which further amplifies the voltage and transmits it to the electromechanical controller (computer board). ).

 

The higher the pressure on the sensor, the higher the output voltage; according to the sensing pressure, the pressure sensor is usually divided into two types: high pressure sensor and low pressure sensor. The high pressure sensor is used to measure the output pressure and load pressure of the main pump. Low pressure sensors are used in pilot control systems and oil return systems.

Common working voltages of pressure sensors are 5V, 9v, 24V, etc. (special attention must be paid to distinguish when replacing). Generally speaking, pressure sensors on the same machine operate at the same voltage. The working current of the pressure sensor is very small, and it is directly powered by the computer board
