Product news on our sensor technologies and success stories from the field
Level measurement in open containers with our hydrostatic probes
Hydrostatic probes allow for precise level measurement in unpressurised, open tanks and vessels as well as in underground applications such as shafts, wells and boreholes. Depending on how they are accessed, the level is detected via submersible or screw-in probes.
Predictive Maintenance 4.0 - Kontinuierliche Ölzustandsüberwachung am Beispiel zweier BHKW-Anlagen
Ein regelmäßiger Ölwechsel ist bei Blockheizkraftwerken mit Verbrennungsmotoren ebenso unumgänglich wie bei Autos. Viele Anlagenbetreiber führen diesen nach wie vor zeitbasiert nach einer bestimmten Anzahl an Betriebsstunden durch. Was hierbei jedoch nicht berücksichtigt wird, ist der tatsächliche Zustand des Öls, weshalb ein Austausch möglicherweise zu früh, zu häufig oder ohne Grund vorgenommen wird.
