Limit switch for foam-, powder-detection and fluids

mipromex® – the security
Type MLS 1100 Limit value evaluation unit
Monitors, detects foams, powders and liquids
The secure limit value unit type MLS 1100 processes the digital measurement signal transmitted by the measurement technology. The intrinsically safe voltage supply to the measurement electronics in the connection head is provided via the signal line. A modern operating and calibration concept with automatic calculation of the measurement range allows for an extremely short commissioning of the analogue measurement. Measurement signal in percent or impulse value are displayed, as selected, on the display. As an output signal corresponds to the measurement value two relay outputs are available.
The membrane keyboard with a functional and fully graphic display contributes toward the user friendliness and safe working.
