Capacitive Interfaces

Loadstar Sensors offers many different kinds of sensors. One of them is based on the principle of change of Capacitance. We make the iLoad Series Capacitive load cells or capacitive force sensors that have either frequency or digital UART or USB output.

When a user wants to connect a capacitive sensor to a PC, PLC, Tablet, or smartphone, he or she will need to use one of the interface devices (also referred to as signal conditioners by some) shown below.

DQ-1000U Frequency to USB Interface

The DQ-1000U interface device provides a convenient way for an iLoad Mini Load Cell to be connected to a PC, Mac or Linux machine via USB or to a microcontroller via UART. It provides the iLoad Mini load cell with regulated power needed to power the load cell, reads the frequency signal from the load cell, applies calibration values to the signal and provides a digital output of the calibrated force, load or weight values.  The output signal is available via UART (Serial TTL) or via USB through the S2U Serial TTL (UART) to USB adapter.

The output data can be obtained at up to 150 Hz with the base DQ-1000U device and at up to 500 Hz using the DQ-1000UHS version of this device. Log and plot and display the data using our compatible LoadVUE Pro software on a Windows 8/10 PC or Tablet.

DQ-1000A Frequency to Analog (& USB) Interface

The DQ-1000A interface is similar to the DQ-1000U but has an additional terminal block that can work off an external power supply and output a 0-5 V DC output proportional to the loads. The DQ-1000A like a DQ-1000U device can work with a PC via USB and can be powered by the USB port itself without need for any additional power supply.

In fact you can operate the iLoad Mini load cell from a PC via USB and display, log and plot data using LoadVUE Pro software and at the same time via the terminal block you can tap into the analog 0.5 to 4.5V DC output to work with PLCs or DAQs! This is a unique feature not available on most other load cells. We call it a hybrid load cell!

4 Port Frequency to USB Capacitive Load Cell Interface

This kit shows four iLoad Mini load cells to be connected to a four-channel version of the DQ-1000U interface. By using four iLoad Mini load cells with a DQ-4000 interface, one can quickly build a moderate accuracy scale by placing the four load cells at the four corners of a frame.

But in addition to UART and USB, this device optionally offers wireless communication and battery operation capability via the DQ-4000ZP/DQ-4000WiFi/DQ-4000BLE versions of this interface. Please contact us for further information or to order items.

4 Port USB Interface & Display for iLoad Mini Load Cells

In addition to all the features offered by the DQ-4000 miniature load cell interface, the DS-4000 device has a built-in LCD screen that displays the individual readings of each load cell as well as the sum total of all connected load cells.

For applications that cannot use a PC or Tablet as a display, this device provides a quick and easy display solution while still enabling data collection on a PC via USB or Wireless protocols.

Touch Screen Displays

Many times instead of connecting a sensor to a PC or to a PLC, one simply needs to show the values on a LCD display. For those instances, we offer these easy to use touch screen LCD displays with one or four channels. The displays are capable of being used wit USB or wireles BLE load cell+interface pairs.

Works with iLoad, iLoad TR, iLoad Mini + DQ-1000U or any load cell mated and calibrated with a DI-100U, DI-1000U or DI-1000BLE interface devices.

Key Features include:

  • Tare and Read Capabilities
  • Change Units as needed
  • Comes with a Power Supply that provides 5 VDC via a micro USB connector
  • Comes with a swivel stand that can be placed on a flat surface and whose angle of display can be adjusted manually
