As a core component of the non-contact displacement measurement system, the 330180-90-05 preamplifier provides a high-frequency radio frequency signal to the eddy current probe and converts the gap change sensed by the probe into a proportional voltage signal (standard output is 7.87 V/mm or 200 mV/mil). The second paragraph describes the electrical characteristics and industrial-grade anti-interference design of this preamplifier.
The 330180-90-05 features a robust A308 cast aluminum housing, is lightweight, and boasts highly integrated internal circuitry with excellent electromagnetic interference (EMI) suppression. It requires an external DC power supply from -17.5V to -26V and is seamlessly compatible with the 3300 series 5mm probe, the 3300 standard 8mm probe, and the 3300 XL 8mm probe and extension cables, achieving extremely high equipment interchangeability without the need for secondary field calibration.
330180-90-05 fully complies with the highest specifications of the American Petroleum Institute (API) Standard 670 (4th Edition) regarding mechanical structure, linear measurement range, accuracy, and temperature stability. It is a globally recognized industrial-grade asset protection and stabilization component suitable for industries such as petrochemicals, thermal power generation, metallurgy, and natural gas transportation.
