Clamp-on current sensing, no PLC
Amper vs. Spall
Amper, now part of ECI Software Solutions, built one of the easiest installs in this category and has expanded beyond monitoring into scheduling, an operator interface, and issue tracking.
Where Amper is strong
- ▸ Setup takes minutes with no interruption to production and no PLC integration required. [ECI Software Solutions, Amper product page]
- ▸ Uses an encrypted cellular connection so install avoids firewall changes, plant Wi-Fi dead zones, or added load on plant IT infrastructure. [ECI Software Solutions, Amper Features]
- ▸ Has grown beyond monitoring into Smart Scheduling, an Operator Interface, and Issue and Maintenance Management modules. [ECI Software Solutions, Amper product page]
- ▸ Was acquired by ECI Software Solutions, a manufacturing execution system provider. [ECI Software Solutions, acquisition announcement]
Where Spall differs
- ▸ Reads straight from the controller: Spall reads part counts, alarm codes, program status, and spindle load directly from the controller, over the machine's own protocols, not a current-clamp estimate.
- ▸ Every finding priced in dollars: Every finding shows a dollar figure, calculated from your own rates, next to the reading it's based on. When there isn't enough data yet, it says so instead of guessing.
- ▸ Pricing on the site: Connected machines run $200/mo each, dropping to $160 from the 11th machine. Sensed-only machines are $125 flat. The price is published up front, no demo needed to see it.
- ▸ 30-day pilot: A 30-day pilot includes the hardware, credited against your first invoice if you continue: line pilot $4,500, plant pilot $8,500.
Spall's pricing, published
Connected machines run $200/mo each, dropping to $160 from the 11th machine. Sensed-only machines are $125 flat. A line pilot costs $4,500 and a plant pilot costs $8,500, both 30 days, hardware included, and fully credited against your bill if you continue. You can see the same number on /product without booking a demo.
What connects
Spall connects to 18 kinds of industrial equipment by name, including OPC-UA, Siemens S7, Allen-Bradley, FANUC FOCAS, MTConnect, Omron, Mitsubishi, and LS Electric controls, PLCs, CNCs, and sensors. If a machine has no controller at all, direct 4-20mA and digital-input wiring reaches it too. Check your own machine list against the table at /protocols before you call.
