The LEVELIS LLU-400 local display unit

Local display unit LEVELIS LLU-400Local display unit LEVELIS LLU-400The LEVELIS LLU-400 local display unit is used to visualize physical quantities (such as fluid level), the magnitudes of which are expressed by means of a signal current 4 to 20mA. The LLU-400 unit is supplied directly from the current loop and is installed between the sensor and the connector head (DIN 43650). The unit parameters (measurement range, decimal point position, damping and the overrange condition) can be set by push buttons accessible after removing  the display cover.
