HUBA694 Differential Pressure Transmitter Product Introduction HUBA694 Differential Pressure Transmitter (Differential Pressure Sensor) HVAC (with or without display), optional digital display. Output signal is adjustable, square root output can be selected. Different measurement range sensors ensure optimal accuracy and long-term stability of measurement, offering great flexibility with multiple options. Not only used for climate control, but also for industrial or medical micro-pressure measurement. Product Features ◆ Model 694 differential pressure transmitter, using the latest ceramic lever technology. ◆ Temperature calibration, signal compensation, such as standard voltage or current output. ◆ User adjustable full scale range from 40% to 100%. ◆ User selectable square root output for differential pressure. ◆ Transmitter can be selected with or without field display. ◆ Main application areas: air conditioning systems, blowers, clean rooms, suitable for gases Technical Parameters Relative pressure and differential pressure -0.5…0.5-50mbar Medium Air and neutral gases Accuracy ＜±1% fs Measurement accuracy Linearity Hysteresis Repeatability＜±0.7% fs Power supply Three-wire: 13.5-33VDC/24VAC±15% Two-wire: 11.0-33VDC Output signal 0-10VDC,0-20mA,4-20mA Wiring method 3wire/2wire Power consumption 10mA, 30mA Protection class IP54 Electrical connection Screw terminal block Pressure connection ￠6.2mm hose connector
