The DAB NIVEAUSND 4-20MA 0.5B 20MT is a specialised level sensor designed for integration with DAB pump control systems. This sensor precisely measures fluid levels and outputs a standardised 4–20 mA signal, allowing for reliable and automated pump control based on fluid pressure or level. Thanks to its robust design and straightforward integration, this model is ideal for applications such as wastewater management, rainwater harvesting, and industrial tank level monitoring.
The sensor operates on direct current (DC) with a supply voltage of 0 volts, meaning it functions as a passive component within a broader control setup. It does not deliver any motor power (P2 = 0 kW), as it is not a drive unit but a purely measuring device. The sensor is suitable for controlling one pump and contains no integrated communication interfaces. It does not support RS-232 or RS-485, nor communication protocols like Modbus, BACnet, KNX, LON, CANOpen or PROFINET.
Supplied with a 10-metre cable, the sensor is well-suited for use in installations that require depth or remote placement. It is not designed for wall or floor mounting and comes without an external housing or control cabinet. The grounding configuration is classified as ‘other’, and the material housing class also falls into the ‘other’ category, indicating a design tailored for specific functional environments.
Electrically, the nominal current and number of phases are zero, confirming its role as a passive sensor. It includes no potential-free contacts, no PWM interface, and no support for temperature sensors such as PT100 or PTC. Additionally, it does not feature any wireless technologies such as Bluetooth, Wi-Fi, or mobile standards (2G/3G/4G/5G).
Although classified under pump control systems, this sensor is specifically designed to function as a level-based signal device within such systems. It belongs to the ‘other’ frequency class, as is typical for analog 4–20 mA sensors, and has an operational range of 0.5 bar, making it suitable for use in buffer tanks, pump pits, and reservoirs.
The DAB NIVEAUSND 4-20MA 0.5B 20MT is a low-maintenance, highly reliable solution for automatic pump system regulation, offering precise measurement and signal control without unnecessary complexity. Perfectly compatible with DAB’s control range, it is an essential component in any smart fluid management setup.
