An instrument company that tests outdoors
SENTIRA Instruments was founded in 2013 by a small team from the optics and radar groups of two Wuhan universities. We build cameras, radar sensors and test instruments, and we sell them to the people who install them, which is why our datasheets list the temperature at which the unit actually works, not the one at which the component survives.
Optics, radar and metrology under one roof
Most of our competitors assemble bought-in modules. We design the lens barrels, the radar front ends and the calibration fixtures ourselves, which means a custom range or a different interface is a change order rather than a new product.
Our customers are systems integrators, distributors and end users in mining, oil and gas, traffic management and manufacturing. Roughly 60 % of shipments are OEM builds carrying someone else's logo.
What happens inside the building
In-house optics assembly
Lens mounting and focus calibration on optical benches, not outsourced.
Environmental test
-40 to 85 °C chambers, IPX6/IPX7 rigs and 2 m drop tests on every housing family.
Calibration laboratory
Pressure, temperature and gas references traceable to national standards.
SMT and conformal coating
Two lines with automated optical inspection and selective coating.
Every unit is burned in before it ships
Assembled units run 48 hours at rated temperature with power cycling, then go through a functional test against the datasheet limits. Calibration certificates are issued per instrument, and the serial number links to the test record.
- 48 h burn-in at rated temperature
- 100 % functional test against spec limits
- Serial-numbered test record archive (7 years)
- Calibration certificate in every carton
