1 INTRODUCTION
1.1 Vibrating wire node overview
Model EWN-01/05/10V series of wireless vibrating wire nodes are designed to expand the data collection
possibilities from vibrating wire geotechnical sensors via wireless network, eliminating the need for running
lengthy cables. It is a reliable integrated system, which is capable of exciting and sampling vibrating wire
sensors and reporting measurements through wireless communications network to the Gateway.
One of the significant advantages of vibrating wire wireless nodes is their ability to provide accurate and
reliable measurements in remote or inaccessible locations. By eliminating the need for physical wiring
connections, these nodes can be deployed in challenging environments where traditional wired sensors would
be impractical or impossible to install. With their wireless connectivity, these nodes offer convenience,
scalability, and cost-effectiveness, empowering industries to gather critical data in real-time and make
informed decisions based on accurate measurements.
1.2 Wireless network
Wireless sensors are vital in monitoring construction sites, large structures and landslide areas. They are
extensively used in applications where geotechnical and other sensors are used for data collection and
transfer it to a central server for access by multiple users. Encardio-rite offers an innovative network solution
that allows real-time monitoring of not only wireless vibrating wire sensor but also other geotechnical and
structural sensors in challenging conditions with reliable data transfer without any delay.
In an end-to-end wireless monitoring system from Encardio-rite, the vibrating wire nodes are interfaced with
the long range, low power radio frequency network to gateway. The vibrating wire nodes send recorded data
to the gateway through the RF network with utmost reliability. The gateway then uploads the collected data
from nodes to the central/cloud server.
The system operates on ISM sub 1 GHz operating frequency bands adjustable to requirement of each
territory. The system can be adjusted to different frequency bands; for example:
India 865 – 867 MHz
Europe 868 MHz
USA/Canada/Singapore/Australia 915 MHz
A detailed reference for frequency bands allowed in different Countries is available at:
https://www.thethingsnetwork.org/docs/lorawan/frequencies-by-country.html
The gateway also has provision to set the frequency band, depending upon the Country.
1.3 Conventions used in this manual
WARNING! Warning messages calls attention to a procedure or practice that if not properly followed could
possibly cause personal injury.
CAUTION: Caution messages calls attention to a procedure or practice, that if not properly followed may
result in loss of data or damage to equipment.
NOTE: Note contains important information and is set off from the regular text to draw the users’
attention.
1.4 How to use this manual
This users’ manual is intended to provide you with sufficient information for making optimum use of vibrating
wire nodes in your applications.

To make the manual more useful we invite valuable comments and suggestions regarding any additions or
enhancements. We also request to please let us know of any errors that are found while going through the
manual.
NOTE: Installation personnel must have a background of good installation practices and knowledge of
fundamentals of geotechnics. Novices may find it very difficult to carry on installation work. The
intricacies involved in installation are such that even if a single essential but apparently minor
requirement is ignored or overlooked, the most reliable of instruments will be rendered useless.
A lot of effort has been made in preparing this instruction manual. However best of instruction
manuals cannot provide for each and every condition in field that may affect performance of the
sensor. Also, blindly following the instruction manual will not guarantee success. Sometimes,
depending upon field conditions, installation personnel will have to consciously depart from
written text and use their knowledge and common sense to find solution to a particular problem.
NOTE: The sensor is normally used to monitor site conditions and will record even a minor change that
may affect behaviour of structure being monitored. Some of these factors amongst others, are,
seasonal weather changes, temperature, rain, barometric pressure, nearby landslides,
earthquakes, traffic, construction activity around site including blasting, tides near sea coasts, fill
levels, excavation, sequence of construction and changes in personnel etc. These factors must
always be observed and recorded as they help in correlating data later on and also may give an
early warning of potential danger or problems.

2 GENERAL DESCRIPTION
2.1 Model EWN-01/05/10V Vibrating wire node
Model EWN-01/05/10V wireless vibrating wire node consists of a small, self-contained unit equipped with a
sensor module that excites the vibrating wire sensor and reads the resonance frequencies, a radio-transceiver
with an antenna, a processor that controls the two modules and power source.
The vw node collects the sensor data and transmits it wirelessly to Gateway. The unit is mounted inside a
compact weatherproof enclosure. The data is transmitted through the long range (LoRa), low power radio
frequency network to the gateway without any signal degradation.
The node is available in variants to connect a single (model EWN-01V) to five (model EWN-05V) or ten
(model EWN-10V) sensors with inbuilt thermistor. The complete range of vibrating wire sensors can be
connected to wireless node including:
Piezometers and water level sensors
Strain gages
Pressure cells
Temperature meters
Displacement sensors, extensometers, crack meters, joint meters
Settlement monitoring sensors
The nodes can be configured to scan and transmit data at any frequency between 2 minutes to 2 hours,
depending on site requirements. The system automatically mitigates well-known wireless problems like signal
blockages and interference, allowing the sensors to reliably send their data to the gateway every time. Every
single radio transmission in the system is secured using AES-128 encryption to maximize security of the
sensor data gathered by the system
2.2 Model EWG-01 gateway
Encardio-rite model EWG-01 wireless gateway is used as a main networking hardware, which uploads data
gathered from all the VW nodes (connected to vw geotechnical sensors) to the Encardio-rite cloud server or a
third party server. In addition, it passes control messages through the network to ensure seamless operation.
The gateway is ideally installed at a location with cellular network, in line of sight of the installed nodes. It
serves as an exit point/central hub for wireless data obtained from the sensors as the readings pass through
or communicate with the gateway prior to being routed to a FTP or cloud server.

4 PRE-INSTALLATION PREPARATIONS
4.1 Pre-installation checks
Before installation please check the tilt meter and gateway for any physical damage.
Open the tilt meter and gateway box to check if the internal wirings are intact.
4.2 Setting up the Gateway and vibrating wire nodes location
Selecting correct locations for Gateway and tilt meter is important, especially in case more than one tilt meter
are being installed at site and connected to single gateway.
The first step is to install the Gateway at a location that is in line of sight with all the installed tilt meters or in
line of sight with most tilt meters. The best location will have to be determined at the site itself. For best
results, the link between the gateway and the tilt meter should be strong, preferably better than -100 dBm.
Please note, the stronger the link better will be the results.
4.3 Setting up the Gateway & Tilt meter
It is recommended that the setting up and configuration of nodes and gateway is done before mounting the
them at respective installation location.
The gateway configuration needs to be done before nodes are configured. For setting up and configuring the
gateway, refer to User’s Manual # WI6002.117 on Gateway. Configuration of vibrating were nodes is
discussed in Section 6 of this manual.
For convenience, a “Quick Start Guide” is included in Section 5 to give a brief and quick idea.
4.4 Sampling Interval for Vibrating wire node
When configuring the Encardio-rite wireless system, it is crucial to select appropriate sampling intervals to
ensure the network operates smoothly without any data loss.
The table below provides guidance on sampling interval selection for vw nodes based on the network size::
Number of Nodes
Minimum Sampling interval(Minutes)
1
4
10
6
50
16
100
28
150
41
200
53
The General formula to calculate Sampling interval for vibrating wire node is:
Sampling Interval (Seconds) = (15*No. VW Node) + 180
