Product Details

MK 9151 - level relay

The MK9151 is used for

Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum fill level, protection against overfilling and dry running
Monitoring and control of the mix ratio for conductive liquids
General resistance monitoring, e.g. recording temperature limits with PTC (device to IEG 255, VDE 0435 section 303)

Features

3 electrode connections for 2-point and 1-point level control
The metering circuit galvanically isolated from the mains is immune from high levels of interference
Max. lead length to the electrodes: 1500 m
Wide setting range: 2 → 450 kΩ which enables differentiation between liquid and foam
Adjustable response and fallback delay: 0.2 → 20 s
Programmable for working current principle (without bridge) or rest current principle (X1-X2 and/or X1-COM bridge)
2 LEDs to indicate operating readiness and contact position
1 changer
Overall width 22.5 mm, protection class IP40
