The Series
629 Differential Pressure Transmitter monitors
differential pressure of air and compatible gases and liquids
with 0.5% accuracy. The design employs dual pressure sensors
converting pressure changes into a standard 4-20 mA output
signal for two wire circuits. Small internal volume and
minimum moving parts result in exceptional response and
reliability. Terminal block zero and span adjustments are
easily accessed under the top cover. The Series 629 Differential
Pressure Transmitter is designed to meet NEMA 4X (IP66)
construction.
APPLICATIONS
Monitor Differential Pressure Across:
- Flow Elements
- Heat Exchangers
- Filters
- Pumps
- Coils
