Warnings Warning Protection provided by the equipment may be impaired if used in a manner contrary to this user manual. This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: 1. This device must accept any interference, and 2. This device must accept any interference received including interference that may cause undesired operation Changes or modifications not expressly approved by Senceive Limited could void the user’s authority to operate the equipment.
Chapter 1 Overview 1.1 The FlatMesh System A FlatMesh network consists of a number of nodes connecting to one gateway device. In some situations multiple networks may be required on a single site, for example a site in which the number of nodes exceeds the number supported by a single Gateway, or a site where there are a set of separate measurement zones. A FlatMesh Node is a sensing unit with an integrated wireless mesh radio and battery.
CHAPTER 1. OVERVIEW Note Readings can be scheduled anywhere between a few seconds to twelve hours with a time increment of one second, but it should be noted that vibrating wire sensors usually require a delay of at least 30-45 seconds between readings for optimum performance. Figure 1.1: Photo of FM3N-VW11 Figure 1.
CHAPTER 1. OVERVIEW 3 1.2.1 Vibrating Wire Sensors Vibrating wire sensors are class of sensor that are often used in geotechnical or structural monitoring applications. The sensor contains a steel wire that is attached to a mechanical system which converts the property being measured to an increase or decrease in the length of the steel wire. This change in the length of the wire corresponds to a change in the resonant frequency of the wire. An electromagnetic coil is located close to the steel wire.
CHAPTER 1. OVERVIEW 4 a frequency range of 200-6000Hz and can be stimulated using a swept sine wave of 6V peak to peak. It has been successfully used with a variety of sensor models, including: • Soil Instruments W9 Piezometer • Soil Instruments ST1 Spot Weldable Strain Gauge • Soil Instruments ST2 Arc Weldable Strain Gauge • Soil Instruments ST4 Embedment Strain Gauge • Geokon 4500S Piezometer Contact your technical sales representative for more information. 1.2.

Chapter 2 Installation The nodes will be delivered to you pre-configured. Simply affix the nodes to a structure within the range of the rest of the network. 2.1 Mounting There are several mounting options for each of the various vibrating wire derivatives. It should be noted that not all mounting options are available for each derivative. Warning The Vibrating Wire Node with brackets could have a mass of up to 1.5kg. Please ensure that the object you are fixing to can handle this load.
Chapter 3 Sensor Wiring 3.1 One-Wire Sensor Connectors The FM3N-VW11, FM3N-VW41 and FM3N-VW81 use M12 A coded 5 pole female sockets for each sensor to be attached. The sensor must have be a corresponding male plug fitted. Ask your supplier for sensors with pre-fitted connectors and connector kits. Figure 3.
CHAPTER 3. SENSOR WIRING 10 3.2 Multi-channel Breakout Box As the connector for the FM3N-VW17 multi-channel device has a high pin count for the connecter size there is no field attachable connector available. Ask your supplier for more details. Sensors with pre-fitted connectors are also available.
Chapter 4 Maintenance The product should not require any maintenance after installation. If the need to clean the product should arise, use only a damp cloth and mild detergent. Do not use any solvents as this may damage the enclosure. Warning Only service personnel authorised by the manufacturer may open the enclosure. No user serviceable parts are located inside.
Chapter 5 Support 5.1 Troubleshooting - General FlatMesh Nodes are sealed units so checking of devices is confided to visual inspection, checking of connections and measurement of basic device parameters. 5.1.1 No new data from node Check if other nodes on the same gateway have been updating The FlatMesh Gateway operates a store-and-forward system. It collects data from nodes on its network all the time, and then periodically establishes a connection to the Web Monitor to transfer data.
CHAPTER 5. SUPPORT 13 Check that the antenna is tight The antenna connects to the node through a threaded SMA connection. This should be tightened by hand against the connector on the enclosure. If this connector is loose, the node’s signal strength and therefore its ability to connect to the network will be significantly impaired. Check that the antenna is correctly oriented The antenna’s orientation can also impact its ability to connect to other nodes.
CHAPTER 5. SUPPORT 14 wires are attached to the correct terminals. Using the free end test harness accessory check that the resistance of both the vibrating wire contact and temperature sensor are within the values as specified in the sensor manual. If you have an external reader and test harness then attach the sensor to the reader and check that the external reader can read the sensor. 5.2.
