Sensor Test Throughput at 65% expected test-station uptime: a worked example

Suppose expected test-station uptime falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate sensor test throughput for security, fire and life safety products using production-ready inputs so teams can confirm whether capacity can cover demand before committing the schedule.

The inputs for this scenario

  • Sensors tested per functional-test cycle: 4 units / cycle (held at the documented default)
  • Available test cycles in the period: 480 cycles (held at the documented default)
  • Expected test-station uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • Expected first-pass test yield: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross sensor test throughput capacity = sensor test throughput output per cycle × available sensor test throughput cycles.
  • Good sensor test throughput capacity works out to 1,211 units at these inputs, and this is the headline figure for the scenario.
  • Gross sensor test throughput capacity works out to 1,920 units at these inputs.
  • Sensor test throughput downtime loss works out to 672 units at these inputs.
  • Sensor test throughput yield loss works out to 37.44 units at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected test-station uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 27.78% below the baseline at 1,211 units.
  • It multiplies output per cycle by available cycles for gross capacity, then scales by uptime and first-pass yield to give good, shippable sensor capacity. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Good sensor test throughput capacity: 1,211 units (headline result)
  • Gross sensor test throughput capacity: 1,920 units
  • Sensor test throughput downtime loss: 672 units
  • Sensor test throughput yield loss: 37.44 units

Run it with your numbers

  • To rerun this with your own numbers, open the live Sensor Test Throughput calculator, set expected test-station uptime to your actual value, and adjust the remaining inputs to match your operation.
