FIXED RANGE PRESSURE TRANSMITTER
Stainless Steel, Explosion-Proof, Accuracy ±0.30%, 4-20 mA or 1-5 VDC Signal
CALIBRATION SERVICES AVAILABLE
PRESSURE
The Series 636 Fixed Range Pressure Transmitter is a low cost, xed range,
stainless steel transmitter with ±0.30% accuracy. It is designed to continuously
measure pressure for years in even the toughest environmental and media conditions.
Transmitters are explosion-proof, (FM approved) and meet NACE standards for offshore applications.
BENEFITS/FEATURES
• Long service life and lower cost to maintain reduces total cost of ownership
• Explosion-proof housing for use in applications where protection of process and
personnel is needed
APPLICATIONS
• Off-shore
• Process applications
