The device enters programming mode by pressing a specific key combination, allowing you to set the level or temperature thresholds for each of the four outputs. Refer to the official HYDAC operating manual for the exact key sequence and menu structure.</p> <strong>What type of fluid is this sensor compatible with, given the ‘K’ designation?</strong><br><p>The ‘K’ in the model number specifies that the sensor uses FKM (Viton) seals. FKM is highly resistant to mineral oils, synthetic hydraulic fluids, fuels, and many chemicals, making it suitable for most standard hydraulic and lubrication applications. However, always verify fluid compatibility before installation.</p> <strong>What does the display show by default, level or temperature?</strong><br><p>By default, the 4-digit LED display shows the current fluid level as a percentage of the probe length. The user can typically cycle through to display the fluid temperature in degrees Celsius or Fahrenheit via the push-buttons. Both level and temperature values are continuously monitored.</p> <p><em>profideals is not an authorized distributor, reseller or representative of the products featured on this website.
