Pulsar, the 'pulse burst radar' of Magnetrol is claimed to be one of the first radars on the market that does not need external software, PC or any other external tooling. It uses no unfamiliar, complex symbols nor signs for customer configuration and set-up. The device shares the same customer interface as the Eclipse guided wave radar (TDR), whose menu structure has reportedly met with much praise from its users. The clear 2-line menu structure where dimensions are entered as level values instead of distance data are a major help for set-up.
The Pulsar is 24 V d.c. loop-powered and equipped with energy efficient circuitry, which avoids duty cycling to accomplish effective measurement. For this reason Pulsar can track level changes up to 4,5 m/min. The universal amplifier is housed in a dual compartment housing and connects directly to a horn or dielectric rod type antenna via a quick connect/disconnect coupling. The antennas are available in different lengths for various nozzle heights. One amplifier can be kept in stock and used with all antenna types via simple, customer software configuration.
The radar emits short bursts of energy at 6 GHz, and measures the transit time of the signal reflected off the liquid surface. Its lower frequency allows the unit to service tougher process applications (foam, agitation) including liquids with dielectrics as low as 1,7. The system uses a linearly polarised microwave beam that can be rotated to improve its performance. Proper orientation will reduce the amount of unwanted reflections from obstructions or sidewall reflections (multipath). Via the menu configuration, it is a simple procedure to have the unit identify false targets and to eliminate these for level evaluation.
The Pulsar series complements the established Eclipse range from Magnetrol, a guided wave radar transmitter for technically challenging applications. The Pulsar is suitable for applications with longer measuring ranges up to 20 m and/or applications with highly viscous or aggressive media.
