4–20 mA Output for Weighing Scales – Seamless Analog Integration for Industrial Automation
Price on Request
At Hindustan Scale Company, we specialize in building scales that speak your system’s language, and the 4–20 mA analog output is the industry standard for a reason. Whether you’re using a platform scale, tank weighing system, hopper scale, or custom-built solution, our 4–20 mA integration ensures precise, real-time analog signals that can be easily interpreted by your PLC, SCADA, DCS, or any industrial control system.
Perfect for batching systems, process control, automation setups, and remote monitoring, this output provides a linear analog signal that represents the measured weight, making it easy to integrate your scale into complex industrial processes. With sturdy build quality, calibration flexibility, and full in-house customization, we ensure your scale fits into your workflow.
- Output range: 4–20 mA corresponding to your desired weight span
- Compatible with all HSCo industrial weighing systems
- Ideal for process industries, pharma, chemical, food, and manufacturing setup
- Reliable signal over long distances with minimal interference
- Simple calibration and scaling through the indicator
- Available with optional dual output, relay, and alarm integration
Integrate your weighing scale directly into your industrial system with reliable, industry-grade analog output. Backed by Hindustan Scale Co.’s trusted legacy since 1955, we build smart, automation-ready solutions that help you measure, monitor, and control with confidence.
Which one is this? The 4-20 mA add-on for a scale you already own (HSCo or most other makes), fitted and configured to your system. Want a new scale with the 4-20 mA built in? See the 4-20 type Customized Scale.
4-20 mA weighing scale output: questions buyers ask
A 4-20 mA weighing scale output carries the weight as an analog current signal to a compatible PLC input. 4 mA is the low end and 20 mA the high end; HSCo sets which weights those two points represent. The output can be fitted to platform scales, tank weighing systems, hopper scales and custom builds for chemical processing, batching and food manufacturing.
4-20 mA carries the weight as a continuous analog current for a compatible input. RS485 carries digital data and can connect several scales on one line; the protocol decides which readings and status fields are sent. Tell us what your controller accepts. We build an analog output, an RS485 connection or both to match it.
Whichever weights your process needs; there is no fixed HSCo span. Tell us the lowest and highest weights to represent, whether the loop is powered by the PLC or by the scale, and the input resistance. We set the output to match your controller and your weighing range.
Platform scales, tank weighing systems, hopper scales and custom builds, and the 4-20 mA Output Customised Scale built for PLC-controlled lines in chemical processing, batching plants and food manufacturing. HSCo can build a relay output alongside it, so the PLC reads the weight and the scale switches a valve at your set point. Any HSCo scale can be built with it.
Fitting the 4-20 mA add-on to another company's scale
Can the 4-20 mA add-on be fitted to a scale or hopper made by another company?
Yes. HSCo fits the 4-20 mA add-on to most other makes of weighing scale and hopper, after first checking the scale’s indicator.
