668C-16

668C-16 is a low cost series 668 differential pressure transmitter. It is capable of measuring low pressures with ±1% accuracy, ideally suited for proper building pressurization and air flow control. Transmitters can withstand up to 10psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability. Compact, lightweight design makes installation simple and easy. Good accuracy at low pressure ranges provides exceptional value for ensuring control and minimizing costly out of specification conditions. Typical applications include variable air volume systems, HVAC and building management.
