WS300 Series Product Overview CTC Connect WS300 Series Wireless Sensors capture and transmit three axes of dynamic vibration signals over a Bluetooth® Low Energy 5 .2 connection, as well as temperature measurements . Within a clear line of sight, they can transmit data as far as 1200 ft/365 m . Data can be accessed via CTC ConnectView Web App running on a CTC Gateway, or through custom software integration with the CTC Connect API and CTC Gateway . WS300 Series sensors are designed for permanent mounting on the machine surface . To prepare the machine surface for installation, spot face, drill, and tap the mounting location . CTC suggests using MH117 Series Installation Tool Kits . To view in depth mounting instructions, please view our Mounting Guide . 4 Battery Installation To avoid premature battery usage, CTC Wireless sensors ship with the battery disconnected . To install, remove the cap and connect the battery’s connector to the receptacle on the back of the exposed circuit board . Tighten down the sensor cap and your sensor will now begin sending out Bluetooth® advertisements for discovery . CTC Gateways and the preloaded Web App will automatically be scanning for these advertisements when running, making all detected sensors visible and autonomously establishing connections to newly discovered sensors . 5 Operation WS300 Sensors have five configurable options – MEMS dynamic range, sampling frequency, reading length, automatic reading interval, and output samples coupling . The sensor will arrive pre-programmed with the following settings: ±32g dynamic range, 12800Hz sampling rate, 6400 samples per reading (per axis), a 12-hour automatic reading interval, and AC output coupling . If any of these parameters need to be changed, it is possible to do so from the sensor page on the CTC ConnectView web app . Readings will occur following the reading rate schedule programmed on the sensor . By default this is a 12 hour interval, but may be changed using the app . Reading data is obtained from the sensor via a direct, active Bluetooth® connection between the sensor and gateway . The ACCESS360 Gateway and ConnectView web app automatically handles this acquisition of reading data . When viewing the data with the CTC app, the raw reading data samples will be displayed in a time waveform plot . An FFT will also be performed and displayed on a separate plot, and overall vibration amplitude measurements will be performed and displayed . Further processing operations, such as integration to velocity, can also be selected to be performed . Automatic readings can also be disabled in the ConnectView app . In this case, readings must be manually triggered while connected to the sensor . Note that whatever reading interval is configured, whether none or some other pre-defined interval, a manual reading can always be taken through the app during an active connection . When using an ACCESS360 Gateway and the CTC ConnectView web app, this can easily be achieved on the sensor page . If the gateway and the sensor in question do not have an active connection, it will automatically establish one for the acquisition . 6 FCC Compliance Statement This device complies with part 15 of the FCC Rules . Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation . CAUTION: The grantee is not responsible for any changes or modifications not expressly approved by the party responsible for compliance . Such modifications could void the user’s authority to operate the equipment . NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules . These limits are designed to provide reasonable protection against harmful interference in a residential installation . This equipment generates, uses, and can radiate radio frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference to radio communications . However, there is no guarantee that interference will not occur in a particular installation . If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: – Reorient or relocate the receiving antenna . – Increase the separation between the equipment and receiver . – Connect the equipment into an outlet on a circuit different from that to which the receiver is connected . – Consult the dealer or an experienced radio/TV technician for help . RF exposure statement This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrol…

DESCRIPTION EQUIPMENT REQUIREMENT Frequency Range VNA E5071C 2.4~2.5GHz Return Loss VNA E5071C < -6 dB Peak Gain (Max) OTA Chamber 3.7dBi Average Total Efficiency OTA Chamber >70% Polarization OTA Chamber Linear Input Impedance VNA E5071C 50 Ohms Note that the above antenna performance is measured with just the antenna mounted on a recommended PCB to similar a free-space condition. When implement into the system, the frequency resonant might be off-tune due to the loading of surrounding components especially metal plane. This off-tune can be compensated through matching. Although module manufacturers specify a peak gain limit, it is based on free-space conditions. The peak gain will be degraded by 1 to 2dBi in the actual implementation as the radiation pattern will change due to the surround components. As such, during selection of antenna, you can select one with high peak gain to compensate for the loss. Molex can offer assistant to choose the best location and best tuning in-order to meet this peak gain requirement.
