System components

extension rod version

Illustrated below are the typical components of a typical IPI installation

TOP HANGER

Used to suspend the complete IPI string. Placed

on the top of the 70mm inclinometer casing

INSTALLATION FORK

(not shown)

Used to support the IPI string during installation. It

fits into two slots on top of the IPI sensor and is

placed on top of the inclinometer casing

TOP STEEL WIRE BOND

A 3mm wire suspension rope used to position the

first sensor at the required depth and is connected

to the top collar hanger and the IPI top fly lead

assembly (G86

502). Available either as pre

assembled lengths (1, 2, 3, 4m) or supplied as site

adjustable

IPI TOP FLY LEAD ASSEMBLY

A universal component which acts as top

suspension and cable connector. Fitted as

standard with 4.5m of digital BUS cable for

connection to a readout or data logger. Other

cable lengths available on request.

PLACE INCLINOMETER PROBE (IPI)

Instrument fitted with one (Uniaxial) or two

(Biaxial) MEMS sensors. It is mounted within a

watertight stainless steel tube fitted with two wheel

sets that run in the internal grooves of inclinometer

casing. One set has a fixed wheel and the other is

sprung loaded. The output from the sensors is

digital RS

485 BUS so that several IPIs can be

connected together on one single cable

EXTENSION RODS

Used to connect each IPI sensor together to

create a tilt profile. Specially designed quick

connecting fittings on each end, together with an

integral internal signal cable. Available in 0.5, 1,

1.5, 2, 3m lengths. (Special lengths are available

on request)

BOTTOM WHEEL/TERMINATION

ASSEMBLY

Fitted with a rigid joint, the bottom wheel assembly

acts as the base reference from which all other

readings are taken. It is fitted with an integral end

termination resistor which is required at the end of

the RS

485 string

SOS 480 WIRELESS DIGITAL NODE

Up to 30 IPI sensors can be attached to each

node
