    🖹 Description

    Dold Level Relay

    The Dold MK9151 series liquid level relay is a single input and DIN rail mount device. It monitors and controls conductive liquids and powders, example maximum and minimum fill level, protection against overfilling and dry running. The 3-probe connections for 2-point and 1-point level control. It has 220VAC to 240VAC supply voltage. General resistance monitoring, example recording temperature limits with PTC (device to IEG 255, VDE 0435 section 303). This device is straightforward to install and safe to use.

    Features and Benefits

    High interference resistance of the measuring circuit, which is isolated from the mains
    Maximum wire length to the probes is 1500m
    Large setting range between 2kohm and 450kohm which permits differentiation between fluid and foam
    Adjustable response and release time delay: 0.2seconds to 20seconds
    Programmable for open circuit operation (without bridge) or closed circuit operation(bridge X1-X2 or X1-COM)
    Green LED for operation
    Yellow LED for contact position
    1 or 2 changeover contacts
    Also available with a sealable transparent cover

    Applications

    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
    General resistance monitoring tasks, e. G. limit temperature detection with PTC
