The PSC-RHO measures the following parameters
• Air pressure
• Temperature
• Relative humidity
Air density is calculated from these values, taking relative humidity into account. Humidity has a significant impact on density, particularly on hot and humid days.
These parameters and the density calculated from them are output via the interface. Data is transmitted as ASCII text in the respective SI units or via the CAN bus.
Air pressure [Pa] → Relative humidity [%] → Temperature [°C] → Density [kg/m³]
e.g.:
96853.055 45.235 20.363 1.188
The transmission rate can be set between 1 and 100 Hz using a simple protocol. Configuration is performed via the USB port. When the device is connected via USB, it appears as a virtual COM port in the system. This allows any software that supports a serial protocol to be used.
For devices with a CAN bus, a DBC file is also included.
Power is supplied via the interface used. Optionally, the CAN bus can be used. In this case, an external power supply in the range of 7 to 24 VDC is required, which is supplied via the interface connection with an M8 connector.
