Model	Description	Order number
	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
