DAB Pump Control System

DAB LEVEL ND 4-20MA 0.5B 20MT – Level sensor with 4-20 mA output | 10 meter cable | For pump control

The DAB LEVEL ND 4-20MA 0.5B 20MT is a specialist level sensor designed for applications in combination with DAB pump control systems. This sensor accurately measures the liquid level and outputs a standardised 4–20 mA signal , allowing simple and reliable pump control based on pressure or liquid level. Its robust design and clever integration make it ideal for applications in wastewater management, rainwater harvesting and other industrial environments where automatic level control is required.

This sensor operates on direct current (DC) and has a connection voltage of 0 volts , which makes it clear that it does not generate any voltage itself, but is used as a passive measuring signal within a larger control system. The output motor power (P2) is therefore 0 kW, since the sensor does not contain a motor, but only serves as a measuring instrument. The sensor is suitable for controlling one pump , and functions completely without integrated communication or digital interfaces. There is no RS-485 or RS-232 communication interface , and protocols such as Modbus, BACnet, KNX, LON or CANOpen are also not supported.

The sensor has a cable length of 10 meters , making it widely applicable for installations with depth or distance to the control unit. It is not suitable for wall mounting or floor mounting and is supplied without housing or cabinet . The earth connection is of the 'other' type, and the material of the housing also falls into the 'other' class, which indicates an application-specific construction that falls outside the standard classifications.

In terms of electrical properties, the nominal current and the number of phases are zero , because this is purely a measuring sensor. There is also no floating switch contact , no PWM output , and no support for temperature interfaces such as PT100 or PTC . In addition, there are no wireless functionalities such as Bluetooth, WLAN or mobile networks (2G/3G/4G/5G).

The DAB LEVEL ND 4-20MA 0.5B 20MT falls into the 'pump control system' class , but is specifically intended as a level sensor for pressure or level control . The sensor supports frequency class 'other' , which indicates that it falls outside of standardized frequency control - typical for analog sensor signals. With a working range of 0.5 bar pressure, it is suitable for use in buffer tanks, pump sumps or reservoirs, for example.

This sensor is an essential component in automated pumping systems, where reliability, accurate measurement and simple signal transmission are essential. The DAB NIVEAUSND 4-20MA 0.5B 20MT offers a maintenance-friendly solution without unnecessary complexity – perfectly matched to DAB's own control systems.
