Description
For simple measuring tasks
The model LS-10 submersible pressure transmitter has
been optimised for simple measuring requirements in level
measurement. It oers excellent quality, is cost-eective and
reliable.
It has been designed to the current demands of the industry
and has a 4 ... 20 mA output as standard, an accuracy of
0.5% and PUR cable. With IP 68 ingress protection, it is
suitable for permanent level measurement up to 328 ft
(100 m) water column.
Submersible pressure transmitter model LS-10
Reliable and long-lasting
The submersible pressure transmitter features a hermetically
sealed and exceptionally robust stainless steel case. The
proven, fully-welded construction ensures a long service life
and permanent sealing.

Description Order number
Cable strain relief clamp
The cable strain relief clamp enables easy and secure mechanical fastening of the submersible 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.
Additional weight
The additional weight increases the dead weight of the submersible pressure transmitter.
It simplies the lowering into monitoring wells, narrow shafts and deep wells. It eectively
reduces negative environmental inuences on the measuring result from the measured
medium (e.g. turbulent ow).
CrNi-Stahl 316L, approx. 500 g, length (L) 130 mm
Junction box
The junction 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.
Filter element
The lter element prevents dirt and moisture from entering the venting tube. The watertight
diaphragm also oers a reliable protection for the submersible pressure transmitter.
