DM8C Vibration Type Liquid Density Analyzer with RS-232C Digital Output High Sensitivity and Excellent Stability
Since 1967, Yokogawa's VD6 vibration-type liquid density analyzer has set the standard for online density measurement in process automation. As density is a fundamental physical quantity critical to industrial processes, the VD6 has earned widespread recognition for its exceptional stability and high sensitivity.
The advanced DM8 vibration-type liquid density analyzer builds upon this legacy, incorporating modern computer technology and multiple sensor techniques. Its microprocessor-based converter directly transforms sensor frequency signals into precise density readings, featuring:
- High sensitivity and stability for reliable measurements
- One-touch calibration using standard solution
- Field-configurable measuring range
- Failure alarm display and output
- Outdoor-rated converter installation
The DM8 analyzer measures liquid density from 0 to 2.0 g/cm³ with outstanding precision, unaffected by flow rate or viscosity. Available configurations include general-purpose, sanitary, and explosion-proof sensors.
