Reference Manual 00809-0100-4480 Transmitter overview September 2020 2 Transmitter overview 2.1 Measurement principle The Rosemount 1408H is a transmitter for continuous level measurements in the hygienic industry. The measurement principle is fast-sweep Frequency Modulated Continuous Wave (FMCW). The transmitter continuously emits signal sweeps with a constantly varying frequency towards the product surface.
Transmitter overview September 2020 2.2.2 Reference Manual 00809-0100-4480 Foam and turbulence Foaming liquids or turbulence may cause weak and varying surface echo amplitudes. Surface turbulence is not normally a problem unless it is excessive. Measurement in foamy applications depends largely on the foam properties. When the foam is light and airy, the actual product level is measured. For heavy and dense foam, the transmitter may measure the level of the foam’s upper surface. 2.

Reference Manual 00809-0100-4480 Configuration parameters September 2020 Alarm set points SP1 - High alarm set point If the measured level is above this set point, the digital output is set to alarm state. SP2 - Low alarm set point If the measured level is below this set point, the digital output is set to alarm state. Hysteresis The hysteresis is a buffer zone so the alerts do not toggle on and off when the measurement value fluctuates around the alarm limit.
Configuration parameters September 2020 Reference Manual 00809-0100-4480 Options for alarm on delay Table C-3: Alarm On Delay Option Description Always Alarm on delay is always used. Lost surface Alarm on delay is used only for lost surface alarms. This may be useful in applications when there are small and local rapid level changes caused by surface turbulence. Hardware faults and measurement values that exceed the alarm set points will trigger alarm without any delay.

In normal operation, the transmitter will drive the output in response to level from the lower to upper saturation points. Note The 20 mA point should be set below the reduced accuracy zone at the top of the tank. Figure C-8: Example of Range Value Settings A B D E C A. B. C. D. E.

Reference Manual 00809-0100-4480 Configuration parameters September 2020 Upper null zone The Upper Null Zone defines how close to the transmitter's reference point a level value is accepted. You can extend this value to block out disturbing echoes close to the antenna, for example from the tank nozzle. Note Make sure the 20 mA value is below the Upper Null Zone. Measurements are not performed within the Upper Null Zone (UNZ).
