Installation Guidelines

The Casper can be installed in the vessel in almost any

position. While installing, please take care of the following
points:

•

Ensure that atleast 10 mm for the "Grounding" elec-
trode on the Casper probe should be completely inside
the application tank. i.e. No part of sense electrode
should be inside the nozzle.

•

Before Installing the device, ensure that the calibra-
tion process has been already carried out in safe area
(Zone 2) then install the instrument in hazardous area
as shown in Figure 51

•

For remote calibration, install the instrument in an ap-
plication tank and then perform the calibration process
in hazardous area (Zone 0).

•

The instrument shouldn’t block the material filling inlet.

•

Secure the cover of housing tightly. Tighten the cable
glands.

•

For side-mounting, provide a baffle to prevent the ma-
terial from falling on the probe. Please refer to Figure
47.

•

To prevent the ingress of moisture and water seepage
in side mounting position, the cable entries should al-
ways point downwards as shown in Figure 48.

•

Make all electrical connections as instructed in the
manual. Don’t power on the device before verifying
connections.

•

Weatherproofness of enclosure is guaranteed only if
the cover is in place glands adequately tightened.
Damage due to accidental entry of water can be
avoided if the instrument is installed in a rain shade.

•

If the ambient temperature is high, the instrument
should not be installed to receive direct sunlight. In
case such a position of shade is not available, a heat
shield should be fitted above the instrument especially
if the operating temperature is 60

°

C.

•

While screwing the Casper, the hexagonal mounting
bush should be turned and not the housing.

Calibration

Calibration for the level sensor has to be carried out at the

installation site. Calibration cannot be skipped and is essen-
tial for level sensor’s operation. Calibration of Casper can be
performed with the help of two different methods which are
as follows:

•

Normal Calibration

•

Remote Calibration
