Test benches developed to specification for each application

NAPRO Eletrônica Industrial designs and manufactures custom test benches for OEMs, Tier 1 suppliers and automotive component manufacturers. Each project starts from the customer's technical and operational requirements and integrates precision measurement hardware, dedicated software and industrial automation into a complete, documented solution.

Our engineering team works across all project phases — from specification to commissioning — developing both the physical measurement and control systems and the data acquisition, analysis and report generation software. The result is an integrated, reliable and traceable solution that complies with the standards and requirements of the most demanding automotive development environments.

Hardware High-accuracy sensors and data acquisition
Software Control, analysis and reporting
Automation PLC, closed-loop, touchscreen
Safety NR10, NR12, NR13

Examples of test benches developed

NAPRO Fuel Test Bench

Fuel Test Bench

Bench developed for performance testing of electric fuel pumps and level sensors (floats). The equipment records pressure, flow rate, current and voltage during hydraulic tests, and simulates height variations to verify the ohmic response of level sensors. Includes a test-fluid temperature control system, stainless-steel tanks, and a console with a computer for control, configuration and report generation.

Tests performedHydraulic performance of fuel pumps and ohmic response of level sensors
Measured parametersPressure (0–12 bar), flow rate (0–350 L/h), current (0–50 A), voltage, temperature and electrical resistance
Temperature controlFluid cooling and heating system with adjustable range
StructureStainless-steel tanks with drain valves and level sensors; surrounding enclosure for vapour containment
Data acquisitionMinimum 2 kHz sampling rate; results export
Pump controlProgrammable power supply and adjustable PWM signal generator for flow-control valve
Dimensions1.5 (W) × 1.0 (D) × 2.0 (H) metres
Power supply220 VAC — 60 Hz
NAPRO Air Conditioning Test Bench

Air Conditioning Test Bench

Bench developed for durability, resistance, leak, performance and validation testing of valves and compressors in automotive air conditioning systems. The equipment operates with nitrogen (N₂) and is designed to test different valve types — shut-off, pressure-relief and control valves (including electronic control) — as well as complete compressors. Complies with NR10, NR12 and NR13.

Components testedShut-off valves (suction and discharge), pressure-relief valves, control valves (mechanical and electronic) and complete compressors
Tests performedDurability, resistance, leak testing, performance and functional validation
Flow measurementHigh-accuracy mass flow meters for ranges from 30 to 1,000 Lpm at up to 500 psi
Pressure measurementDifferential, gauge and absolute pressure transducers; maximum operating pressure 60 bar
Temperature measurementType T thermocouples with range –200 °C to +370 °C
AutomationPLC with digital and analogue I/O; computer with touchscreen monitor
SoftwareConfigurable display of values in SI and imperial units; CSV logging; USB export
SafetyCabinet with transparent polycarbonate doors, exhaust system, pressure-relief valve; NR10, NR12 and NR13
CalibrationAll sensors and meters with RBC calibration certificates
Cabinet dimensions2.0 (D) × 0.9 (W) × 2.0 (H) metres
Power supply220 VAC — 60 Hz — single-phase
DocumentationInstruction manual, maintenance routines, spare parts list and calibration certificates
