Submersible pressure sensor
Description
The model LS-1000 submersible pressure sensor continuously measures the level of liquid media in industrial environments. It records the level hydrostatically from 1 ... 10 m [3.28 ... 32.81 ft]. Optimum long-term stability ensures precise measured data and minimal signal drift. Hermetic leak tightness is ensured by the robust design and a specially developed cable with integrated strain relief. Due to its attractive pricing, the LS-1000 submersible pressure sensor is the ideal choice for OEM customers.

| Additional weight The additional weight increases the dead weight of the submersible pressure sensor. It simplifies the lowering in monitoring wells, narrow shafts and deep wells. It effectively reduces negative environmental influences of the medium (e.g. turbulent flows) on the measuring result. Stainless steel 316L, approx. 300 g [0.661 lb], length 115 mm[4.53 in] | 14131008 | |
| Cable strain relief clamp The cable strain relief clamp ensures easy and secure mechanical fastening of the submersible pressure sensor's cable. It serves to guide the cable to prevent mechani- cal damage and to reduce the action of tensile stresses. | 14052336 | |
| Cable socket The cable socket, with IP67 ingress protection and waterproof ventilation element, provides a moisture-free electrical termination for the submersible pressure sensor. It should be mounted in a dry environment, outside any shafts or vessels, or directly in the control cabinet. Not suitable for hazardous areas! | 14052339 | |
| Filter element The filter element prevents dirt and moisture from entering the capillary tube.The waterproof diaphragm also offers a reliable protection for the submersible pressure sensor in the harshest environments. | 14052344 |
