A submersible pressure sensor for hazardous areas
The LS-1000 submersible pressure sensor (photo) is now certified in accordance with the European ATEX and international IEC-Ex directives. The sensor continuously measures the level of liquid media in industrial environments. Thanks to the new approvals, companies can now also use it in hazardous areas of ATEX zone 0 and 1, as well as IEC-Ex zones 0, 1 and 2. This applies to applications in the process industries, wastewater and environmental technology and power generation. Typical applications include wastewater lifting stations, pumping stations and oil and fuel tanks. The LS-1000 measures levels hydrostatically from 1 to 10 m (3.28 to 32.81 ft). Optimal long-term stability of 0.2% ensures precise measured data and minimal signal drift. Thanks to its robust design, the stainless-steel submersible pressure sensor is permanently sealed in accordance with ingress protection IP68. A specially developed cable provides effective strain relief, and potting of the cable inlet provides additional protection. Each individual device undergoes a helium leak test during the final inspection. The submersible pressure sensor is maintenance-free, and can be operated with a 5-V battery. — WIKA Alexander Wiegand SE & Co. KG, Klingenberg, Germany
