BTS Bluetooth Telemetry System

Bluetooth Low Energy (BLE) Strain Bridge Transmitter Module

Get Your Free Quote

The BTS-AM-1 is a Bluetooth Low Energy (BLE) strain bridge transmitter module that provides access to high quality measurements on a mobile platform such as a phone or tablet.
The delivery mechanism is BLE which utilizes the flexibility and availability of Bluetooth receivers while maintaining the low power requirements of embedded systems. BTS is built upon two complimentary principles of BLE: 1) broadcast advertising data which enables users to deliver the same data to multiple receivers simultaneously and 2) low power paired connections which can be used in a point to point system.

A free iOS and Android app is available for download, which enables users to create dashboards with varying degrees of detail based on application requirements. It enables BTS systems to be visualized on phones and tablets by using digital displays, gages, tanks and charts. Displayed data can be defined as mathematical expressions consisting of readings from multiple transmitters, functions and constants. The app also facilitates BTS module configuration and calibration.

Features and Benefits

  • High Measurement Resolution: BTS-AM-1 can produce a noise free resolution of 1 in 92000 counts (16.5 bit) when used with a 3mV/V sensor and 1 in 184,000 counts (17.5 bit) when used with a 6mV/V sensor.
  • Simple Integration into iOS and Android Apps: Advert format and encoding as well as details on connected services are available to facilitate integration of the device within custom apps for OEM applications.
  • Range: Ranges achievable between 30 to 90 m line of sight depending on age and quality of viewing device.
  • Advanced Protection: Configuration PIN, View PIN and Calibration PIN allow you to take control of your end users experience and prevent any unwanted changes in configuration that can compromise measurement quality.

which allows the module to be built into OEM applications.

WTS/BTS-BC1
The WTS/BTS-BC1 is a battery charger and power supply suitable for the 3V transmitter modules. The WTS/BTSBattery Charger is designed to supply a constant 3.3 V from a Li-ion Battery while also charging the battery from an input voltage. The unit comes pre-configured to provide a charging current of 466 mA suitable for VARTA LIP653450. This module also supports additional batteries providing a charge current of 133 mA via the removal of the leaded resistor (non surface mount).

Power

Attach power supply wiring to the module as shown below:

! Battery Voltage should not exceed 3.75V. Care must be taken when charging secondary cells.

Sensor

The resistance of the strain gauge can be between 85 and 5000 ohms. The BTS-OEM-1 can support up to four350 ohm strain gauges bridges attached in parallel (At the expense of reduced battery life).

The cable lengths between the BTS and the gauges should be kept below 0.5 meters and generally as short aspossible. As the measurement is a four wire connection, as the cable length increases the voltage drops in the cable will have more of an effect on the factory mV/V calibration.

The strain gauge measurement is bi-directional, i.e. tension & compression.

Digital Connections

The digital input and output connections are shown above. The two digital lines provide a TTL input/output with a 1 kΩ input/output impedance respectively.

Reset Communications

Shorting the two PTH holes during power up restores the communication characteristics as follows.

Name – B24
DataTag – Last four hex digits of ID
Calibration PIN – 0000
Data Rate – 1 Second
Fast Mode – Disabled
