| 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 mechanical damage and to reduce the action of tensile stresses. | 14052336 | |
| 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. 500 g [1.1 lb], length (L) 130 mm[0.51 in] | 14052341 | |
| Terminal box The terminal box, with IP67 ingress protection and waterproof ventilation element, provides a moisture-free electrical termination for the submersible pressure sensor. It should be mounted in dry environment or directly in the control cabinet. | 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 |
