Details

The CRI350 Siemens Piezo Full-Functional Tester is a highly specialized, compact, and smart diagnostic tool designed for testing and repairing advanced Piezoelectric injectors. Covering major brands like Continental, Siemens VDO, Bosch, and Denso (Euro 4, 5, and 6 emission standards), this device integrates a touchscreen driver box, a dedicated piezo air flow tester, and a high-precision wireless Bluetooth micrometer. It provides the ultimate solution for checking the health of the piezo crystal and ensuring precise mechanical assembly clearances.

Product Advantages:

Comprehensive Piezo Diagnostics: Offers 6 core testing functions including Insulation Test (up to 1000V), Capacitance & Resistance Test, Stroke Test, Gap Test, Flow Test, and Continuous Resistance (R/T) Test.
Smart Wireless Measurement: Features an advanced Bluetooth digital micrometer for the Stroke Test. It measures the elongation of the piezoelectric ceramic core in real-time and automatically draws the driving voltage characteristic curve on the screen.
Precision Gap & Flow Testing: Accurately measures the air clearance (gap) of the solenoid valve to ensure proper assembly. The independent air flow tester (running at 5Bar/53V) uses a float flowmeter to verify if the injector's return air and flow performance meet OEM standards.
Compact & Safe Design: Extremely portable (Net weight: 5.5 kg) yet highly protective. Its high-voltage insulation and resistance tests prevent mechanics from testing short-circuited injectors that could otherwise burn out the test bench driver.

Application Scenarios:
An essential tabletop tool for professional diesel fuel injection repair shops, specialized piezo injector remanufacturing centers, and automotive diagnostic laboratories looking to overhaul Siemens/VDO and other piezo systems.
FAQ:

Q: Which injector brands are supported by the CRI350?
A: The tester comes with various harnesses to support Piezo injectors from Continental, Siemens VDO, Bosch, and Denso.
Q: How does the Stroke Test work on this machine?
A: By using the included Bluetooth micrometer, the device measures how much the ceramic crystal expands or contracts under different driving voltages (0-160V) and generates a linearity curve on the screen to analyze fuel output stability.
Q: What is the purpose of the Continuous Resistance (R/T) Test?
A: It monitors the resistance of the piezoelectric crystal over time in real-time. This helps technicians determine the long-term durability and stability of the Siemens VDO injector (an optimal value is >199kΩ).
