In direct mode (if the dielectric constant is high), the level signal is a reflection on the surface of the tank contents. If the dielectric constant is low, the device uses TBF mode. The device in TBF mode uses the radar reflection on  the bottom of the tank (the signal goes through the tank contents). The tank must have a flat bottom for the device to operate correctly in TBF mode. This menu item is set by default to "Direct" for tank contents with an εr >1.8. If εr is very low (<1.6), use "TBF Full". If εr is low (εr= 1.5...1.7), use "TBF Partial" mode. "TBF Partial" is an automatic mode that lets the device make a selection between "Direct mode and "TBF" mode. If you use "TBF Full" or "TBF Partial", enter the dielectric constant in menu item 2.5.3 Er PRODUCT. Refer also to "Measuring principle" on page 90.Direct, TBF Partial, TBF Full Direct2.5.5 Er PRODUCT For measurement in TBF mode only.

The radar principle used is FMCW (Frequency Modulated Continuous Wave).The FMCW-radar transmits a high frequency signal whose frequency increases linearly during the measurement phase (called the frequency sweep). The signal is emitted, reflected on the measuring surface and received with a time delay, t. Delay time, t=2d/c, where d is the distance to the product surface and c is the speed of light in the gas above the product.For further signal processing the difference Δf is calculated from the actual transmitted frequency and the received frequency. The difference is directly proportional to the distance. A large frequency difference corresponds to a large distance and vice versa. The frequency difference Δf is transformed via a Fourier transformation (FFT) into a frequency spectrum and then the distance is calculated from the spectrum. The level results from the difference between the tank height and the measured distance.Figure 8-1: Measuring principle of FMCW radar1  Transmitter2  Mixer3  Antenna4  Distance to product surface, where change in frequency is proportional to distance5  Differential time delay, Δt6  Differential frequency, Δf7  Frequency transmitted8  Frequency received9  Frequency10  Time

 DESCRIPTION OF HART INTERFACE 9115OPTIWAVE 7400-24 Cwww.krohne.com12/2015 - 4003518001 - MA OPTIWAVE7400-24-R01-en9.1  General descriptionThe HART® Protocol is an open digital communication protocol for industry. It is free to use by anyone. It is included in the software embedded in signal converters of HART-compatible devices.There are 2 classes of devices which support the HART® Protocol: operating devices and field devices. There are 2 classes of operating devices (Master): PC-supported workstations (Primary Master) and manual control units (Secondary Master). These can be used in control centres and other locations. HART® field devices include sensors, converters and actuators. Field devices include 2-wire and 4-wire devices, and also intrinsically-safe versions for use in hazardous areas.There are 2 primary operation modes for HART-compatible devices: point-to-point mode and multi-drop mode.If the device is used in point-to-point mode, the HART® Protocol uses the Bell 202 Frequency Shift Keying (FSK) standard to put a digital signal on top of the 4...20 mA signal. The connected device sends and receives digital signals that agree with the HART® Protocol, and sends analog signals at the same time. Only 1 device can be connected to the signal cable.If the device is used in multi-drop mode, the network only uses a digital signal that agrees with the HART® Protocol. The loop current is set to 4 mA. You can connect a maximum of 15 devices to the signal cable.An FSK or HART® modem is included in field devices and manual control units. It is necessary to have an external modem for PC-supported workstations. The external modem is connected to the serial interface.9.2  Software historyHART® identification codes and revision numbersINFORMATION!In the table below, "x" is a placeholder for possible multi-digit alphanumeric combinations, depending on the available version.Release date Devices HART®Device Revision DD Revision2008-03 All revisions 1 2Manufacturer ID: 0x45Device: 0xE5Device Revision: 1DD Revision 2HART® Universal Revision: 7FC 375/475 system SW.Rev.: ≥1.8AMS version: ≥7.0PDM version: –FDT version: ≥1.2
