Product Description

HPM18V is a capacitive vacuum gauge, also called a capacitive thin film vacuum gauge (CDG). This product uses a ceramic capacitive sensor as a sensitive element and directly measures pressure using a vacuum connection. Its analog output signals such as 0-5 or 0-10 VDC are proportional to the measured pressure and are not affected by the type and composition of the process gas. Ceramic has the characteristics of high elasticity, wear resistance, corrosion resistance, and fast heat dissipation, which makes the vacuum gauge have very good thermal stability and low temperature drift.
 
HPM18V capacitive vacuum gauge has high measurement accuracy, excellent overpressure resistance and excellent long-term stability. Its corrosion-resistant ceramic sensor is temperature compensated, has a wide operating temperature range, and has good zero-point stability. The vacuum gauge is compact in overall size, easy to use and reliable, and is suitable for accurate measurement of medium and low vacuum with complex gas composition.
