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. For ease of installation and maintenance, order optional 3-valve manifold assembly.

Monitor differential pressure in air/liquid flow systems, HVAC/R automation, pneumatic systems and process control with the Series 647 Wet/Wet Differential Pressure Transmitter. Units are temperature compensated and provide a 4 to 20 mA output signal.

Capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization and air flow control. Can withstand up to 10 psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Units also feature reverse-polarity protection.
