SERIES 645 Wet/Wet Differential Pressure Transmitters

SERIES 645 Wet/Wet Differential Pressure Transmitters are designed for use with
compatible gases and liquids which can be applied to both the pressure and reference
ports. Quick response capacitance sensor delivers a 4 to 20 mA output signal
proportional to differential pressure with ±.25% accuracy. The Series 645 transmitters
are ideal for process control, filter condition monitoring, refrigeration equipment,
pump speed control, HVAC equipment, and liquid level measurement. For ease of
installation and maintenance, order optional 3-valve manifold assembly. Bleed ports
allow for total elimination of air in the line and pressure cavities.
FEATURES/BENEFITS
• Versatile, high-accuracy device for liquid or gas supports designs requiring more
precise measurements in support of application
• Optional 3-way valve manifold supports simplifying installation or removal of
transmitter without interrupting process
APPLICATIONS
• Process control • Filter monitoring
• Refrigeration equipment • Pump speed control
• HVAC equipment • Liquid level measurement
