• Resolution to better than 1 part in 10,000
• Accuracy and repeatability to less than 0.1% of span
• Microprocessor based capacitance level transmitters with on
board digital to analog conversion assuring negligible output
current error of 0.003%
• Linearity of better than 0.003% over industrial temperature
range of -20˚F to 160˚F
• Designed with most up to date surface mount, integrated
circuits and components
• Standard range of 0.0001 picofarads to 15,000 picofarads
allowing the 4220 to span 4-20mA over 1 inch of water,
(high sensitivity) or hundreds of feet of water (low sensitivity)
• Non interacting zero and span
• Cancel Coat™ circuitry and superior resolution eliminate the
readout errors cause by conductive coatings on the continuous
level controls sensing probe
