DS-3000U Pro - Touch Screen Display for Digital Load Cells and USB Load Cell Interfaces

DS-3000U Pro - Touch Screen Display for Digital Load Cells and USB Load Cell Interfaces

Loadstar Sensors offers a variety of digital load cells, weight sensors or weight scales with USB or Wireless output.  The iLoad Series and the iLoad Series offer direct USB Output through out S2U UART to USB miniB to USB A adapters.  The DI-100U/DI-1000U USB Load Cell Interfaces can be mated to any of our resistive load cells to obtain calibrated USB output. 

Although any Windows Tablet (e.g. Surface 3, Surface 4 or Surface Pro) or All-In-One PC can be used as a very effective and rich display with a GUI environment using our LV-1000/LV-4000/SensorVUE/ControlVUE software, a number of customers have asked us for a simple, dedicated Touch Screen LCD display for use in factory and laboratory settings where use of PCs may not be appropriate.

In order to meet our customer requests, we have developed a display solution - the DS-3000 Pro - using a Raspberry Pi 3 (RPi3) controller and Touch Screen display as shown below. Our solution comes ready to use out of the box, all you need is to plug in the sensor and power our display using the provided power supply.

Load Cells with USB, UART, & Analog 0-5V Output shown in various configurations

Load Cells with USB, UART, & Analog 0-5V Output shown in various configurations

The iLoad Pro load cell is one of the family of load cells that use capacitive measurement techniques to measure forces or loads.  Unlike traditional strain gauge load cells, these capacitive load cells do not use resistive strain gauges that are bonded to a metal member.  Instead it uses two capacitive plates separated by a gap as the sensing element.  When the load/force is applied, this gap changes changing the capacitance.  This change is measured and transmitted as a digital signal directly from within the sensor and can be in the UART or USB format.  In addition, an analog voltage (0-5 V DC) can also be output as an option simultaneously making it easy to use for a wide variety of application!
