FlowGuard 6279 AutoZero Pressure transmitter.
The FlowGuard 6279 is an advanced processor transmitter with optional AutoZero [Z] added, aimed for the standard pressure measurement tasks. It’s designed with the user and installer in mind. The 6279 eliminate many of the problems that traditional sensors suffer from and provide as much flexibility as possible.
The unit has field selectable features like signal output (mA or Volt) and Signal volt outputs (0-10, 0-5, 2-10). Different predefined measuring ranges (5, 10, …. depending on selected models) are available. And to simplify the installation, the 6279 uses display and push buttons to make the settings easy.
With these options in one sensor you can cover e.g. static duct pressure measuring (unidirect [U] sensor), or most situations for room pressure measurements. And if the 6279 is ordered with Bidirectional sensor [B] it’s possible to measure both positive and negative pressures. The analogue output will be at middle point of selected output range when pressure is at zero for the bidirect model.
The sensor has a silicone membrane and works with capacitive technique. It’s extremely accurate and durable. To further improve it, auto calibration is an option added on this sensor for applications where any small drift over time is not accepted, e.g. as in hard to reach locations, or when the sensor is configured for very low pressures like ± 5 Pa.
And the pressure reading can be reached by BMS through the Modbus if wanted. The Modbus feature adds more value to the product since all settings and parameters can be reached from a BMS/Scada.
