Technical Specifications

Core Advantages & Features

• Original-Grade Signal Processing: Utilizing the same 2G.1 signal control architecture as the original manufacturer, this board features a low-noise circuit design. It effectively filters electromagnetic interference, ensuring linear stability across both high and low leak rate ranges, meeting the stringent requirements of semiconductor and new energy industries.
• Universal Compatibility: This single board is compatible with three major oil-sealed helium leak detector models: ASM142, ASM182, and ASM192. This versatility simplifies inventory management for maintenance facilities and repair shops.
• Non-Destructive Installation: The PCB dimensions, mounting hole positions, and multi-channel wiring terminals are a 1:1 replica of the original P0520E1. It allows for a "plug-and-play" replacement without the need for cutting wires, welding, or modifying the analyzer chamber.
• Industrial-Grade Durability: Built with high-temperature resistant and anti-interference industrial electronic components, the board is designed for 24/7 production line environments. It withstands the electromagnetic noise from vacuum pumps and motors, preventing gain decay or short circuits.
• High-Voltage Protection: Integrated voltage stabilization and current-limiting circuits ensure a steady high-voltage output to the ion source. This protects sensitive leak detector accessories like filaments and electron multipliers from voltage spikes.

Detailed Design & Build

The P0520E1 OEM board is meticulously crafted to address common equipment failures such as sensitivity loss, fluctuating leak rate values, and communication errors within the analyzer cell. By choosing high-quality leak detector accessories, users can significantly reduce maintenance costs and minimize production downtime.
