How do you calculate sensor test throughput?

Multiply output per cycle by available cycles for gross capacity, then multiply by uptime and yield. With 4 units/cycle over 480 cycles at 90% uptime and 97% yield, good capacity is 1,676.16 units.

What's the difference between gross and good test capacity?

Gross capacity is nominal — 1,920 units from 4 units/cycle x 480 cycles. Good capacity subtracts downtime and test-failure losses, leaving 1,676.16 units that actually ship.

How much capacity does test downtime cost?

At 90% uptime the station loses about 192 units of gross capacity to downtime before yield is even applied. Restoring full uptime would recover most of that on this line.

What is a good first-pass test yield for life-safety sensors?

Well-controlled smoke and CO sensor lines run 95-99% first-pass. The 97% default is healthy; it costs roughly 52 units of yield loss on this run.

How do I add test capacity without a second station?

Raise uptime and yield first. Moving uptime from 90% to 96% at the same 97% yield lifts good capacity from 1,676 toward 1,788 units — a large gain with no new fixture.

Why not just use gross capacity for planning?

Because gross capacity assumes zero downtime and perfect yield. Planning to 1,920 when you can only ship 1,676.16 good units leaves you 244 units short against the panel line.

Security, Fire & Life Safety Products calculator

Sensor test throughput Calculator

Sensor test throughput measures how many good, verified sensors a functional-test station actually clears once downtime and test failures are accounted for. Test and manufacturing engineers on smoke, heat and CO detector lines use it to size test capacity, staff shifts and confirm a station can keep up with panel assembly demand. It matters because life-safety sensors require full functional verification before shipment, and a test cell that looks fast on paper can bottleneck the whole line once uptime and first-pass yield are honest. This tool turns nominal test capacity into shippable good-unit capacity.

What this calculator does

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.
Use it when sensor test throughput in security, fire and life safety products is being asked to take on more work and you need to know if there is room.
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.

Formula used

Gross sensor test throughput capacity = sensor test throughput output per cycle × available sensor test throughput cycles
Good sensor test throughput capacity = gross capacity × expected sensor test throughput uptime × expected sensor test throughput first-pass yield

Inputs explained

Sensors tested per functional-test cycle:
Available test cycles in the period:
Expected test-station uptime:
Expected first-pass test yield:

How to use the result

Use it to size test-cell capacity against demand, plan test-station staffing, or justify a second fixture when the good-unit number falls short.
It applies flat average uptime and yield, so it won't reveal burst downtime or a specific failure mode that a per-defect Pareto would surface.

Current U.S. benchmarks

Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
