1. Important details for your information

Read these operating instructions before installing and starting the pressure transmitter. Keep
the operating instructions in a place that is accessible to all users at any time.
The following installation and operating instructions have been compiled by us with great care
but it is not feasible to take all possible applications into consideration. These installation and
operation instructions should meet the needs of most pressure measurement applications. If
questions remain regarding a specific application, you can obtain further information (data
sheets, instructions, etc.) via our Internet address (www.wika.de / www.wika.com ) or contact
WIKA for additional technical support (see section7 Starting, Operation/Further information).
With special model number e.g. LS-10000 or LH-11000 please note specifications in the
delivery note. The product data sheet is designated as PE 81.09
WIKA pressure transmitters are carefully designed and manufactured using state-of-the-art
technology. Every component undergoes strict quality inspection before assembly and each
instrument is fully tested prior to shipment.

4. Function and accessories

LS-10: Submersible pressure transmitter for level measurement, standard version.
LH-10: Submersible pressure transmitter for level measurement, High Performance.

Function: With the level probe you measure the hydrostatic pressure of your application,

which is trans-formed into an electric signal. This electric signal changes in proportion to the
hydrostatic pressure and can be evaluated correspondingly.

Accessories: For details about the accessories, please refer to WIKAs price list, WIKAs

Diaphragm test for your safety

It is necessary that before starting the pressure transmitter you test the diaphragm, as this is
a safety-relevant component.

n Pay attention to any liquid leaking out, for this points to a diaphragm damage.
n Check the diaphragm visually for any damage.

!

Warning

Installation

n Use the pressure transmitter only if the diaphragm is undamaged.
n Use the pressure transmitter only if it is in a faultless condition as far as the

safety-relevant features are concerned.

n An additional strain relief is not necessary because the cable has a max.

tensile strength of 1000 N (500 N with FEP).

n The protection cap (A) protects the secluded diaphragm (B) from damaging

the level probe duringtransport and immersion. Remove the protection cap if
used with viscous or contaminated media.

n There must be no differences in potential between medium/tank and the

grounding of the junction box and the control cabinet when the shield of the
cable is applied.
