USB Load Cell
The World's first all in one USB Load Cell. The USB port powers the load cell as well as communicates sendor data. LoadVUE Pro software makes it effortless to connect, display, log and plot force data on a PC or Tablet.
Digital Load Cell with UART or USB Output
We extended the concept of a USB Load Cell to ANY resistive load cell based on the wheatstone bridge network by offering a Digital Load Cell Interface. This interface enables a user to work with any load cell built using strain gauges and works on a mV/V bridge network concept and connect it to a PC/Tablet via USB or to a micro-controller via UART.
Wireless Load Cell with Xbee, WiFi or BLE Output
We offer the finest interface devices to to connect a sensor to a PC, Mac, Linux machine or an iOS phone or tablet. Whether you want to do it via BLE, WIFi or XBee (802.15.4) wireless protocols we make it easy for you. An included rechargeable battery allows you to sense data cordlessly not just wirelessly.
Load Cell with Analog Output (0-5 V DC Voltage or 4-20 mA Current)
Programmable Logic Controllers (PLC) are used to activate external devices like valves, motors, pumps, lights and alarms. If you want to connect a sensor to a PLC or a Data Acquisition System, we offer the AI-1000 Analog Interface that offers high level 0-5 VDC analog output and the AI-1000-CV with a 4-20 mA output.
Load Cell with LCD Touch Screen Display
For quality control applications, weighing applications and others that need a simple LCD touch screen display, we offer the DS-3000-Pro Touch Screen LCD Displays. We offer two models - one for a single sensor or scale and a four channel display for up to four sensors.
Connect a Load Cell to an Arduino or Raspberry Pi
If you want to connect a sensor to a microcontroller to build an embedded application we offer the DI-100U interface with UART connectivity. Just add an S2U Serial to USB dongle to get USB output to connect with a Raspberry Pi. We provide the finest interface that gives you the broadest range of options to connect to the widest range of processors and computing devices.
Wireless Load Cell with BLE Output and IoS
If you want to connect to an iOS device like an iPhone or iPad, the easiest and best way is to connect a resistive load cell to our DI-1000BLE. An included rechargeable battery allows you to sense data cordlessly not just wirelessly for a couple of hours of continuous use. The LoadVUE iOS software can be downloaded for free from the Apple AppStore.

FAQ
The company was founded in 2003 with the idea of developing easy to use digital PC friendly force measurement solutions. In 2010, Loadstar Sensors was purchased by and operates as a wholly owned unit ofYPoint Capital, Inc. We have over 10,000 customers in 85+ countries and have over 20 issued patents. We are located in the heart of Silicon Valley in Fremont, CA.
A capacitive load cell works on the principle of change of capacitance in response to applied forces. When a force is applied, it changes the gap between two capacitive plates. This change is transduced into a change in frequency of the output signal. Instead of minute changes in voltage, one can get change in frequency and conver this into a measure of force.
A resisitive load cell is built using strain gauges arranged in a wheatstone bridge network. A strain gauge is basically a resistive element that is piezo resistive i.e. it changes resistance in response to changes in strain (change in length over original length). Applied forces lead to induced stresses that lead to displacement and strain. The change in strain leads to a change in resistance. So with an applied inout voltage one can measure tiny changes in voltage and use this to infer the applied force.
We offer signal conditioners that allow you to connect to a computer (PC. Mac or Linux) via USB or wirelessly via XBee, WiFi or BLE protocols. We also offer sensor interfaces with UART output to connect to a microcontroller to develop an embedded application. Our analog signal conditioner makes it easy to get analog 0-5 V voltage output or 4-20 mA current output. Or simply connect to our touch screen LCD display to show values on a simple physical display.

We need between one and two weeks usually to ship your order for items in stock. This is because we have to make your sensor, interface and calibrate them together, make sure the quality meets all specs and then pack and ship it to you. We offer expedited processing options if you are in a rush and need to get sensors sooner. If out of stock or if sensors are needed in volume, we could take 4-6 weeks or longer. Please contact us to get an estimate of price and lead time for your particular needs.
