The PSU housing of microLEVEL sensors has been specially developed to cope with tough environmental conditions. The devices can be installed in virtually any tank for a pressure-tight configuration. At the sensor end, the device conforms to IP68/10 bar protection. The entire sensor has IP69K conformance and is suitable for steam-jet cleaning. With the new model, SIE Sensorik has built a maximum of functionality and dependability into a minimised size. The sensors have been designed for reliable detection of all water-based and/or conductive media.
The extended service temperature range of +105°C, together with the option of autoclaving, makes these devices suitable for applications in the pharmaceutical, food and beverage industries.
The smartLEVEL technology is particularly adept at compensating for deposits and encrustations. The version with a test pulse on the switching signal line (available on request), provides almost complete monitoring of the sensor functions while in operation. This variant has been developed specifically for safety-relevant applications.
NO/NC coding with simultaneous PNP or NPN circuitry can be implemented with just one single sensor type via the three connecting leads. Versions are available with a 3 x 0,25 mm² PUR lead or a standard M8 x 1 plug connector.
At the launch of this new range, versions are supplied with an M12, G1/4" and NPT 1/4" fixing thread.
A reverse-mount type with a pressure gland at the cable end enables customers to easily create rod-type probes of any desired length for use as limit switches.
The microLEVEL sensor offers easier implementation in existing applications and, thanks to its reduced dimensions, can also be conveniently used in more compact machines and systems.

Level Measurement & Control
Ferric chloride and other acids are essential chemical substances in water and wastewater treatment. To control the dosing of acid solutions, an Australian wastewater treatment plant uses a special container to store, mix and add these chemicals. The company opted in favour of KROHNE’s OPTIWAVE 1540 radar level transmitter

Level Measurement & Control
A municipal utility in eastern Germany operates a state-of-the-art wastewater treatment plant with sustainable sludge treatment. The ultrasonic signal was being partially deflected by the wind, leading to frequent false measurements and inefficient process workflows. The problem was solved by replaced the ultrasonic level sensor with KROHNE’s OPTIWAVE 1540 non-contact radar.
