The LS-1000 measures levels hydrostatically from 1 ... 10 m [3.28 ... 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. Even the smallest leaks and hairline cracks are detected here.
The submersible pressure sensor is maintenance-free, minimising failures, downtimes and total cost of ownership. It can be operated with a 5 V battery, as the energy-saving ratiometric 0.5 ... 4.5 V output signal consumes less than 5 mA. This places such a low load on the battery that it does not need to be replaced for years.
