Dwyer 645-11 PRESSURE TRANSMITTER, 1/0/1 PSID WET/WET

• 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.
• Ideal for process control, filter condition monitoring, refrigeration equipment, pump speed control, HVAC/R 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.
