RSB6 Low Profile Pancake Load Cell with Through Hole

These low profile pancake load cells come with a through hole that can be used to measure tensile or compressive forces. They have excellent accuracy, temperature compensation and convenient mounting features. They can be fastened to a fixed surface from the top with six or eight available mounting holes with a counterbore.

You can buy just the Load Cells or buy the Load Cells with interface devices such as analog signal conditioners, digital USB or wireless load cell interfaces, displays and software as complete ready to use kits.

Mounting Options

The RSB6 through load cells have a threaded mounting holes for applying loads. One can attach ropes/cables/hooks using eye bolts or swiveling rod ends as shown below. The sensors need to be fully supported on the rim of the base. The through mounting holes with counterbore holes can be used to fasten the load cell to a fixed surface. They can be mounted and used in any orientation. Does not need to be verically mounted. The measured force will be the relative force between the two ends of the load cell. You can use an optional inline tension adapter under the load cell to obtain a matching threaded center hole to make it easier to apply in line tension or universal loads.

Load Cell Configurations

The RSB6 Through Load Cells are based on the classic wheatstone balanced bridge network design using strain gages. The baseline output is mV/V i.e. if you supply say 10V to the sensor, then the output voltage may vary from 0 mV to 20 mV for a 2 mV/V device. They can be mated and used with digital or analog signal conditioners (digital or analog interfaces) to connect with PCs, PLCs, or simple LCD diplays. We offer the following options:

USB Load Cell with DI-1000U Configuration

If you need to do testing and data gathering or want to display values on a PC/Tablet via USB, simply connect the load cell to the DI-1000U Digital Load Cell Interface & use the USB connector on the DI-1000 to connect to a PC via the USB port. The DI-1000U is a signal conditioner & 24-bit digitizer (good enough to handle load cells with 0.02% of full scale accuracy) and handles all the communications functions to talk with USB port of a PC.  When connected this way, the load cell appears on the PC as a virtual COM port. Using a standard terminal emulator you can send commands to the sensor to display loads on screen. They can be displayed either one reading at a time or in continuous operation mode. You can also use Matlab, LabView or other popular programs to communicate and get calibrated readings from the load cell. It would be best if used our LoadVUE Pro application to display, log or plot data on a PC.

USB Load Cell with DI-100U Configuration

If you do not need the very high precision of the DI-1000U, you can use our DI-100U digital load cell interface with 16 bit ADCs and Serial TTL or USB output.  The DI-100U is sufficient for accuracies of +/- 0.1% of full scale output.  Or in other words if you need to measure +/- 1 lb accuracy over 1000 lb range or +/- 0.1 lb accuracy over 100 lb range, then the DI-100U is more than adequate for your application. If you wish to connect a load cell with an Arduino or other microprocessors or microcontrollers, then you can disconnect the S2U Serial to USB converter adapter and directly communicate via UART.

USB Load Cell with LCD Display

If you don't want to use a PC or PLC and just want a simple LCD display, you can use our DS-3000-Pro Touch Screen LCD Display. The load cell needs to be mated with a DI-100U or DI-1000U and calibrated together as a pair. This pair can be used with the display or with a PC or tablet. This it gives you a load cell, a DI-1000U USB Interface, LoadVUE Pro software (to use with a PC to display, log and plot data and recalibrate if needed) plus a Touch Screen Single Channel Display if all you need to do is just use for operations for a quick display.

FAQ

Why do you call it a through hole load cell?

The RSB6 load cell has a through hole at the center of the load cell where the force is supposed to be applied. Also even though it has a low profile, it can be used to apply loads up to 5 tonnes or 5000 kg (11,000 lb).

What is unique about the RSB6 Load Cell?

The through hole at the center makes it unique among all load cells we offer. With just compression calibration, you can use it to measure forces in tension or in compression!

What technology is used to make the RSB6 load cell?

The through hole load cell is built using strain gauges arranged in a wheatstone bridge network around a hub and spoke structure. 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.

Do you offer signal conditioners and displays?

We offer signal conditioners that allow you to connect to a computer (PC. Mac or Linux) via USB (DI-100U or DI-1000U) or wirelessly via XBee, WiFi or BLE protocols (DI-1000ZP/DI-1000WiFi/DI-1000BLE).
We also offer sensor interfaces with UART output (DI-100U) to connect to a microcontroller to develop an embedded application. Our analog signal conditioner (AI-1000 and AI-1000-CV) make 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.

What software do you offer?

We offer free LoadVUE Lite software to display force/weight on a Windows 8/10 PC/Tablet. The LoadVUE Pro software allows you to display, log & plot force/weight data, recalibrate sensors and get remote support. SensorVUE extends support to an unlimited number of sensors as well as all types of sensors we offer. ControlVUE software extends the functionality offered by SensorVUE and adds the ability to control external devices based on sensor values through a USB Relay with one to eight channel. Our sensors and interfaces allow you to write your own code as well! We also offer customization and custom softrware development services to meet your specific needs!

Do you offer calibration service?

Yes. We offer calibration service on new sensor purchases as well as recalibration service for previously purchased sensors. We use NIST traceable reference standards to perform and validate the calibration and provide a free calibration certificate as part of the service. We are NOT ISO certified.

How can I get pricing information?

You can register on our website, login and see all prices, download spec sheets and solid models. You can also send us an email with your contact information and shipping address and we will be happy to send you a formal quote.

What is your return policy?

We give you a 30 day guiarantee for you purchase. You can exchange or return your purchased products for a refund of the purchase price of the product. Any calibration service fees, shipping and payment fees cannot be refunded. Feel free to try out our products risk free and see for yourself how easy we make it for you!

What is the typical lead time?

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.

Do you offer educational discount?

We believe teaching young kids and encouraging R&D is crucial to make this world a better place. We support teaching and research activities in educational institutions with a 10% education discount on purchased products in exchange for sharing write ups, pictures, video clips and other material we can use in our marketing materials on and off line.
