Differential Transmitters

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.

Senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The housing is specifically designed to mount on a 35 mm DIN rail in a panel. Mounting style allows for several units to be mounted closely together reducing required space. The span and zero controls are for use when checking calibration.
