The PS0+ point sensor and the PSO point sensor are used to detect electrically non-conductive liquids such as oil, enabling the location of the leak to be detected quickly.
The PS0+ point sensor and the PSO point sensor are used to detect electrically non-conductive liquids such as oil, enabling the location of the leak to be detected quickly. Thanks to the special optics, the PSO+/PSO can operate reliably also when facing metallic surfaces (e.g. oil catch pan made of sheet steel). The integrated load relay can operate actuators, such as a check valve, directly on site. A second change-over contact reports the circuit state to the monitoring electronics. The point sensor can be supplied centrally with DC 24 V via the signal cable. It is similarly possible to provide voltage decentrally by means of a commercially available plug-in power supply unit. With its additional terminal block, the PSO+ can be combined with the SCR and PS sensors as required. The monitoring electronics RLW, RLAnet, RDW03 and RDA01 as well as corresponding accessories (see catalogue) are also part of the BARTEC water detection system.
