Pressure transmitter for HVAC systems
4 - 20 mA, 0 - 10 V Allen Bradley

Our HVAC Pressure Transmitters measure positive, negative or differential pressure in the ranges of 1.00...12 in. wc (25.4...304.8 mm wc). The piezo resistive sensor monitors the pressure for air or other clean inert gas. Our Current-to-Pneumatic transducer converts a 4...20 mA input signal to a pneumatic output signal to position pneumatic damper and valve actuators in HVAC systems.
