🖹 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
