ENGINEERING CALCULATORS
Choose the calculation you need
Free tools for motor current, voltage drop, cable sizing, analog signals, pump power and energy consumption.
Results from these tools are approximate values intended for information and preliminary sizing. They must not be used alone as final design, product-selection or implementation values. Final decisions must be verified against site conditions, applicable standards, manufacturer data and review by a qualified engineer.
Motor Current Calculator
Calculate current and approximate apparent power for single or three-phase loads.
Open calculator ↗02Voltage Drop Calculator
Voltage drop based on line length, current, conductor size and power factor.
Open calculator ↗03Cable Size Calculator
Preliminary cable sizing using both current capacity and voltage drop.
Open calculator ↗044–20 mA and 0–10 V Calculator
Bidirectional conversion between analog signals and engineering values.
Open calculator ↗05Pump Power Calculator
Hydraulic and shaft power from flow, head, density and efficiency.
Open calculator ↗06Energy Consumption Calculator
Energy consumption and estimated cost from power and operating time.
Open calculator ↗ENGINEERING NOTE
Fast calculation, clear assumptions, correct interpretation
The tools are intended for preliminary assessment and checking. Alongside each result, we explain the formula, assumptions and field conditions that require attention.
