Details
  • The clogging indicator is a microprocessor controlled pressure switch with two alarm outputs for alert and shut-off.
  • A display of LED's with different colours viewed from under a transparent cover. After power is turned on, green LED’s start flashing, indicating that the system is active. A pressure sensor continuously controls the pressure loss in the filter head and a temperature sensor simultaneously registers the temperature
  • of the fluid . After the oil has reached the operating temperature (which is typically above 30°C), the green LED’s stop flickering. The sensor is then in operational mode.
  • When the contamination capacity of the filter element has been reduced to approx. 25%, the display changes to yellow. If 100% of the capacity is reached, red and yellow LED’s are displayed and the alarm outputs activate.
  • The signal points can be set closer to the cracking pressure of the bypass valve due to the high accuracy of the pressure sensor. This allows greater use of the filter capacity and saves operational cost.
  • Since there is no flow across the filter if the system is running idle, no pressure loss can be measured. Therefore the visual and electrical alarms are self-locking until either power has been cut off or the Reset-button is pressed, at the latest after the next replacement of the filter element.
  • Additionally, the device has a self-checking function. In case of malfunction, the red LEDs start blinking and signal output 2 is activated without switching on the yellow LEDs. As an option the capacity sensor monitors if the system starts-up without the filter element installed.
