Buy 4355012 4248773 7223203 High Pressure Sensor for Hitachi EX100-3 EX120-5 | Tonkee®

Pressure Range: High-pressure sensors must be capable of measuring pressures within the hydraulic system accurately.

The pressure range specifies the minimum and maximum pressure values that the sensor can handle. For excavators, this range is typically quite high to accommodate the demands of heavy-duty operations.

Accuracy: Accurate pressure measurement is crucial for the proper functioning of hydraulic systems. The accuracy of a sensor is usually expressed as a percentage of the full-scale pressure range. Higher accuracy ensures precise control of hydraulic functions.

Temperature Range: Excavators operate in diverse environmental conditions, so high-pressure sensors must be able to function reliably across a wide temperature range. The temperature range specifies the minimum and maximum temperatures within which the sensor can operate effectively.

Output Signal: High-pressure sensors generate an output signal that corresponds to the measured pressure. Common output signals include analog voltage or current signals, as well as digital signals. The choice of output signal depends on the control system of the excavator.

Construction and Materials: The sensor's construction and the materials used are essential for durability and resistance to environmental factors.

Heavy-duty construction and materials ensure that the sensor can withstand the harsh conditions of construction sites.

Electrical Connections: The sensor must have appropriate electrical connections compatible with the excavator's control system. This includes considerations for wiring, connectors, and any necessary electrical protection.

Vibration and Shock Resistance: Excavators are subject to significant vibrations and shocks during operation. High-pressure sensors must be designed to withstand these mechanical stresses to ensure long-term reliability.
