DESCRIPTION OF EQUIPMENT
The Nivus P Series of Ultrasonic Level Sensors are designed as level measurement sensors used in level
measurement systems. The sensors in the series differ only in the size of transducer crystal used and
the frequency of operation.
The equipment comprises a printed circuit board and a piezo electric crystal transducer, these are all
housed inside a plastic enclosure and then totally encapsulated.
connection facilities to the external circuits.
The equipment has been assessed with the following input parameters:
Variation 1 - This variation introduced the following changes:
i.
To permit the P Series of Ultrasonic Transducers to be extended to include the model P 25.
ii.
To allow the amendment of the label to include additional information that is not ratified by Sira.
Variation 2 - This variation introduced the following change:
i.
To recognise the inclusion of the Model P 40 into the range of Pulsar P Series of Ultrasonic Level
Sensors.
Variation 3 - This variation introduced the following changes:
i.
The recognition of modifications to the printed circuit board (PCB) for form a P Mk2 circuit board.
ii.
To permit the use of the dB Mk2 circuit board in all previous models within the P series of
Ultrasonic Level Sensors.
iii.
The inclusion of the Model dB6 Mk2, standard, and the dB6 Mk2, threaded nose versions into the
range of Nivus P Series of Ultrasonic Level Sensors.
Variation 4 - This variation introduced the following changes:
i.
The introduction of minor changes to the printed circuit board and parts list.
Variation 5 - This variation introduced the following changes:
i.
To allow the enclosure used in the construction of the sensor to be made from an alternative,
plastic material.
Variation 6 - This variation introduced the following changes:
i.
The recognition of the P-40 version of the equipment.
