It is called a weigh module because it is a sub-assmbly with a load cell, a base plate and a top plate with mounting holes to make it easy to simply place a weight on it or bolt on a "foot" from a pressure vessel or tank easily onto it.

They are essentially a "scale" that can be incorporated into your process control application such as a chemical mixing tank, beer or wine brewing tank etc. They have excellent sensitivity, accuracy and thermal stability over a wide range of temperatures from -10C to 40C. But most importantly they use load cells that are able to compensate for off center loading so the weights can be placed anywhere over a certain area without compromising accuracy. And have convenient base and top that can be adapted for your particular application.

The single point load cell is a resisitive load cell device. It 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.

The RSP1 load cell and RAPG load cells are almost identical in design except for the fact that the RAPG is much smaller in size and is offered in capacities as low as 100 grams. If you need to measure loads in sub gram accuracy then the RAPG is the load cell for you!

NTEP is standard set by the US Dept. of Commerce for weighing systems used for trade to sell products by weight. If you sell say coffee beans by the lb then you are supposed to use an NTEP rated scale (and hence an NTEP rated load cell). The RRP1, RRP2 are NTEP rated single point load cells.

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.

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!

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.

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.

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!

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.

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.
