Differential Pressure Transmitter (0 - 10" W.C.)

The Series 668 Differential Pressure Transmitter is capable of measuring low pressures with a +-1% accuracy - ideally suited for proper building pressurization and air flow control. Transmitters can withstand up to 10 psig 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. Units also feature reverse-polarity protection. Features: * ood accuracy at low pressure ranges provides exceptional value for ensuring control and minimizing costly out of specification conditions * High overpressure rating eliminates possible damage to unit reducing unnecessary service time
