| Description | Order number |

| Cable strain relief clamp The cable strain relief clamp enables easy and secure mechanical fastening of the submersi- ble pressure transmitter's cable at the measuring point. It acts as a guide for the cable, in order to avoid mechanical damage and to reduce the tensile stress. | 14052336 |
| Additional weight The additional weight increases the dead weight of the submersible pressure transmitter. It simplifies the lowering into monitoring wells, narrow shafts and deep wells. It effectively reduces negative environmental influences on the measuring result from the measured medium (e.g. turbulent flow). Stainless steel 316L, approx. 500 g, length (L) 130mm | 14052341 |
| Terminal box The terminal box, with IP 67 ingress protection and watertight ventilation element, provides a moisture-free electrical termination for the submersible pressure transmitter. It should be mounted in dry environment or directly in the switch cabinet. | 14052339 |
| Filter element The filter element prevents dirt and moisture from entering the venting tube.The watertight diaphragm also offers a reliable protection for the submersible pressure transmitter. | 14052344 |
