1.2 Designation of inclinometers
Inclinometers are used for measurement (by two mutually transverse axes X and Y) of tilt
angle of buildings, structures or controlled structural elements.
The most popular spheres of use of inclinometers are as follows:
1. Platforms position and alignment control;
2. Position and movement parameters monitoring of the controlled object;
3. Alarm notification in the case of critical change of the controlled object’s position;
4. Security systems;
5. Navigation.
The inclinometers can be used separately or in the structure of a distributed measurement
system used for control of tilt angle of industrial, residential and municipal facilities. The
inclinometers can be easily installed on the controlled facility without the need to connect any
external primary transducers.
1.3 Operational environment
The inclinometers have industrial version available and can be used in adverse operational
environments. This allows to use them in hostile environments with high mechanical and vibrational
load. It is allowed to use the inclinometers with labelling 0ExiaIICT6X in explosion-hazard areas.

Figure 2.5 Contacts labelling for connection to measuring network
Connectors FQ14-4ZK-S are intended for connection of the digital inclinometer to the
connecting cables of the measuring line. The connecting cable from the side of measuring line is
connected to the connector via interface converter, while the other connector (if necessary) is
connected to the connecting cable, thus allowing to increase the measuring line length up to the
next inclinometer. Thus, there is formed a sequential structure of the inclinometers (connections of
“wye” or “star” type are not allowed) with parallel connection to the electrical circuits of the
measuring line.

2.4 Digital inclinometers: mounting
It is possible to mount the inclinometers directly to the controlled surface (the inclinometer
package has 4 mounting holes with 4,5 mm diameter).
In order to provide the possibilityof inclinometer adjustment by azimuth and horizon, one can
use the adjustment plate for mounting of the inclinometer (Figure 2.6). The adjustment plate has
four holes with 5.5 mm diameter for mounting on the controlled surface.
Figure 2.6 Mounting of ZET7x54 with the use of adjustment plate
The selected range of tilt angle measurements for measuring axes of the inclinometer is valid
only in the case if the zero values of both measuring axes of the inclinometer correspond to its
horizontal position.
Note: during mounting of the inclinometer one should observe the directions of the measuring
axes specified on the package of the device –it is necessary to secure correct alignment of the
inclinometer by azimuth.

4Digital inclinometers: parameters configuration
Note! The Manufacturer reserves the right to change the version of digital transducer’s
software version. The sequence of software version updates up to the current version is described
in the document «Software_Service work with ZET7ххх.pdf».
4.1 Configuration of interface part of the digital inclinometers
Configuration of interface part should be performed in accordance with the instructions
specified in the document «Configuration of interface part of the intellectual modules of ZET7ххх
series».
Please note that it is necessaryto set unique address for every device in the measuring network
in the section «Address (node) from 2 up to 63» of the “Information” tab. In order to secure normal
operation of the measuring network, it is necessary to make sure that all the devices of the measuring
network have unique addresses. The addresses are set in the range from 3 up to 63.
Note: digital transducers ZET 7х54 consist of two channels (channels names by default are
as follows: «Axis X», «Axis Y»), corresponding to the two measuring axes. When assigning the
addresses, please note that the channels of digital transducers ZET 7154 have two addresses in the
measuring network, while the channels of digital transducers ZET 7054 are assigned a common
address.

4.2 Functions and composition of the tabs used for configuration of measuring part of the
digital inclinometers
Digital transducer consists of two channels (by default, the names of the channels are: “Axis X” and
“Axis Y”). It is possible to configure parameters of the digital transducer only in the tab of the channel
“Axis X”. As the parameters of the channel “Axes X” are changed, the system automatically applies
the corresponding changes to all other channels.
4.2.1 The tabs «Axis Х» and «Axis Y»
Digital inclinometer ZET7х54 contains two mutually transverse channels X and Y. The tabs
“Axis X” and “Axis Y” contain information of the channel parameters, that are further specified in

Example №1: The digital inclinometer is mounted at the controlled element of a structure,
which is located in position, in relation to which it is necessary to control the tilt angle. Select the
option “Off” in the field “Offset”, save the settings, wait for stabilization of digital inclinometer
readings (for ratio α=0.005 the stabilization time is approximately 15 minutes –you can visually
control the stabilization process with the use of the program “multichannel oscilloscope” from the
scope of ZETLab software). Then select the option “On” and save the settings again. The digital
inclinometer will start recording the change of the tilt angle in relation to the set zero value.
Example №2: In order to measure the absolute angle, set the digital inclinometer at even
horizontal surface, configure the settings so that to take the offset into consideration (see Example
#1), then place the inclinometer at the controlled surface and measure the angle.
