POTENTIOMETER TRANSMITTER
(CE, non-isolated)

Functions & Features
• Providing a DC output proportional to a potentiometer or slidewire position input
• Constant voltage excitation allows use with pots with total resistances from 100 Ω – 10 kΩ without affecting accuracy
• 50 % zero/span adjustments with minimal interaction
• High-density mounting
Typical Applications
• Tank levels
• Positions
