Datasheet - IL9151

COO (Country of Origin):: DE

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

Liquid Level Relays are used to monitor the levels of conductive liquids, and are available in Up/Down, Minimum, Maximum, and Fill/Empty variations. Liquid Level Relays are straightforward to install and safe to use.

Application Examples

Liquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media, and designed specifically to provide for the:

Monitoring and control of liquid levels

Protection of pumps against dry running

Ability to detect liquid leaks in a system

Control of media mixing ratios

Control of liquid levels
