Wireless solution and technology: T7 Series Labjack
The Labjack T7 USB or Ethernet is multifunctional DAQ equipment that has 14 analog inputs (ranges between 6-18 bits) and 2 outputs (ranges 12 bits). It has 23 digital I/O and 10 counters timers as well.
The T7 series Labjack provides high range of flexibility to the users and very much useful for receiving signals from the virtual sensors. It holds three different communication interfaces and the can serve senor data through those interfaces (Osseiran et al. 2016). The low latency sampling and control system of T7 series is made up with easy command response Modbus messages. The waveform is generated required to be generated from stream out.
- The system is competent of stand-alone operation by running Lua scripts.
- It must provide resolution setting for different software configuration
- Stream mode is needed to be used to deliver high speed configurable sampled rate
- Both the single ended input and differential inputs are needed to deliver the desired outcome of T7 series (Sturmer et al. 2016).
- There are different options of communications such as the through USB, Ethernet and 802.11b/g.
- The product named as T7-PRO Labjack, is required to be operated in a perfect temperature range. After analyzing the product it has been found that the minimum temperature in which the device can operate accurately is -40 and the maximum temperature is 85. It also serves actively monitored and highly informative forums on which the users can share their views and thoughts to others.
- For configuration, testing and logging data to the files it also serves free applications to the users (Magno et al.2015). These devices can be operated over any platform that supports the TCP/IP (Transmission control protocol).
- In order to convert voltage to either pressure or temperature simple slope or offset is required. Thermo couples, load sells and even bridges are also required to make the systems operates efficiently.
The technical information of t7 pro Labjack includes different cost requirements such as in general the input is14XAnalog, 23X digital I/O and in maximum temperature it could operate efficiently. The measurement cost of t7 pro Labjack is higher than the others and the width, height and depth in which it could be operated are respectively 152 mm, 66 mm and 16 mm (El-Kader and El-Basioni 2013). Moreover, it could be stated that, the unit of the t7 pro Labjack should have to cost effective and competitive in the marketplace. Though based on the types and other features of the products the price range varies.
The sampling rate of Labjack t7 pro is 100 Hz and for building essential communication bridge between the receiver and the transmitter Ethernet or 802.11b/g WI Fi is needed to be used by the users. In order to make this communication, the communication frequency changes as per the changing requirements. The power needed to operate the t7 PRO Labjack is 5VDC and the input voltage range of this device are ±10V, ±1V, ±0.1V and ±0.01V.
