Product Specifications

Technical details and manufacturing context for Gauge or Sensor

Definition

This component is a gauge or sensor used within an Oil Level Indicator system to measure the quantity or height of oil in reservoirs, tanks, or machinery. It provides critical monitoring data to prevent equipment damage from insufficient lubrication or overfilling. The device operates through various methods, including float-based mechanical displacement, capacitance measurement, ultrasonic reflection, or pressure differential sensing, to determine oil level and transmit this information to display units or control systems. Typical materials include stainless steel for wetted parts, plastic housing, and electronic components. Key parameters include a measuring range of 0–100 mm (standard; custom ranges available), accuracy of ±0.5% FS, output signal of 4–20 mA (two-wire loop powered), supply voltage of 12–36 V DC (reverse polarity protected), operating temperature of -40–85 °C for electronics (probe can withstand higher), process temperature of -40–120 °C for wetted parts, operating pressure of 0–2.5 MPa (max overpressure 4 MPa), ingress protection IP67 per IEC 60529, wetted parts material 316L stainless steel per ASTM A240, process connection G1/2 per DIN 3852, and weight of 0.5–1.0 kg depending on probe length. These values are directory references and must be confirmed for the specific model and application. The device is suitable for outdoor installation. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement or installation.

Working Principle

The gauge or sensor determines oil level using one of several physical principles. Float-based devices use a mechanical float that moves with the oil surface, transmitting position via a lever or magnetic coupling. Capacitance sensors measure the change in dielectric constant between electrodes as oil level varies. Ultrasonic sensors emit sound waves and measure the time for reflection from the oil surface. Pressure differential sensors compare hydrostatic pressure at different depths. The resulting signal is converted to a standard output (e.g., 4–20 mA) for display or control.
