FlowGuard 6280 AutoZero Pressure transmitter.
The FlowGuard 6280 is an advanced processor transmitter with optional AutoZero [Z] added, aimed for the standard pressure measurement tasks. The 6280 eliminates many of the problems that traditional sensors suffer from and provides 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 in the menu.
With these options in one sensor you cover most situations for room pressure measurements. E.g. an application with positive room pressure the Unidirect [U] sensor model is selected. And the High & Low alarms is used with the CPS single mode. Or a Bidirect [B] sensor is selected and you can select if you use the rooom in either Positive or Negative pressure. The output is configured to Bidirectional mode (zero pressure = middle of analogue output signal). The 6280 High & Low alarm works with the CPS system in the selected positive or negative room in a Single room mode. The installation is simple with the 6280 using the display and push buttons configuring the settings.
The sensor has a silicone membrane and works with capacitive technique. It’s extremely accurate and durable. To further improve it, auto calibration is added on this sensor for applications where any small drift over time is not accepted, e.g. in hard to reach locations, or when the sensor is configured for very low pressures like ± 5 Pa.
With the optional relay a simple alarm function can be achieved. An example is measuring pressure in a room. If pressure is too low a LED light tower connected directly to the 6280 relay will warn staff with a light by the door. Simple and quick installations. The alarm level can be reached by Modbus if wanted. Through Modbus all settings and parameters can be reached from a BMS/Scada.
