Pressure Range:
Pressure sensors typically have a specified range within which they can measure pressure accurately.
For construction equipment, this range might be tailored to the hydraulic system's operating pressures.
Accuracy:
The accuracy of a pressure sensor is crucial for reliable operation. It is usually expressed as a percentage of the full-scale range. High accuracy ensures precise monitoring and control of hydraulic pressures.
Output Signal:
Pressure sensors can provide analog or digital output signals. Analog signals are often in the form of voltage (e.g., 0-5V) or current (e.g., 4-20 mA). Digital sensors may use communication protocols like CAN (Controller Area Network) for seamless integration into modern equipment.
Electrical Connection:
Specifications for voltage supply, signal output, and electrical connections are essential for proper integration into the equipment's electrical system.
Environmental Specifications:
Construction equipment operates in diverse and challenging environments. Pressure sensors should be designed to withstand conditions such as vibration, temperature variations, and exposure to dust and moisture.
Material and Construction:
The materials used in the sensor's construction must be compatible with hydraulic fluids. Additionally, sensors need to be robust to endure the harsh conditions often encountered in construction sites.
