Pulsonic Pulsar 420

Intelligent Level Transmitter

  • Single Point Transmitter

sensor and processing electronics all contained in single

  • 4-20mA Output Computed As Direct Units of Level or Distance

  • Simply Programmed

the unit is programmed via either a laptop (using Windows
95) or a personal organizer (using a standard communications
package). There is no additional software to purchase.

  • Intelligent Diagnostics

Level, distance and engineering parameters can be viewed directly
on a laptop or a personal organizer.

  • High-Resolution Sensor

operating at 80kHz, the ultrasonic sensor offers the highest
operating performance available.

  • High-Resolution Output

With a 12 bit ADC the analogue retransmission output resolution
is better than 0.05%.

  • Rugged Weatherproof Enclosure

using a strong structural Polyurethane foam housing, the
unit conforms to IP65 weatherproof rating.

  • Built-In Temperature Compensation

an integral temperature sensor maintains accuracy of the
ultrasonic signal at all time.

  • Wide Operating Range

operating distances: 0.25 to 6.0m or 0.4 to 12.0m .

  • Simple Installation

easily installed using flange or bracket mountings.

  • Low Cost

low purchase cost – low maintenance cost.

  • Ideal For Plc And Scada Integration

the Pulsar 420’s simplicity and versatility make it an
ideal solution for integration into multi-sensory applications.

High Performance 4-20mA Level Transmitter

Recognising the need for a low cost, smart and highly accurate
transmitters for the water, wastewater and process industries,
Pulsonic Technologies have launched the Pulsonic Pulsar 420 for
level applications at OEM prices.

As all software is embedded in the Pulsar 420, the user can
access the programming mode by using Hyperterminal in Microsoft
Windows Accessories menu, or a VT100 communications programme
if using a personal organizer. The major benefit of this is
that the Pulsar can easily be programmed either in the field
or the factory prior to installation. An added feature of
the Pulsar is the ability to read real time level values
and perform engineering diagnostics when connected to a PC
or personal organiser.

Not only does the Pulsar contain the latest electronic
technologies, but also includes new, advanced ultrasonic sensors.
Using ultrasonic transmission frequencies far in excess of
our competitors, and specially researched acoustic materials,
the Pulsar can truly claim to be world-beaters where high
resolution, fast response and high performance are required.
