Product Description

HPM18LV is a high-precision Capacitive Diaphragm Gauge (CDG) that utilizes a temperature-compensated ceramic sensor to provide gas-independent pressure measurements with exceptional thermal stability, corrosion resistance, and long-term reliability. By delivering a standard 0-10 VDC analog output, this robust vacuum gauge ensures seamless integration and compatibility with international brands, making it an ideal solution for accurate monitoring in complex medium-to-low vacuum environments.

Product Features

• Capacitive thin-film principle
• High precision and good stability
• Excellent overload resistance
• Detection is unaffected by gas type and composition
• Fast response and low hysteresis
• Direct pressure measurement: analog output signal is proportional to the measured pressure
• Supports various pressure interfaces in the vacuum industry, such as KF, CF, and VCR
