3.4 Mag -03MS - Figure 4
This square section enclosure is manufactured from reinforced epoxy and the sensing
elements are mounted with reference to the base which acts as a datum face.
The Z axis is aligned to this reference face to an accuracy of 0.1
°
. The orthogonality error
between the magnetic axes is also 0.1
°
for this sensor compared to the standard 0.5
°
error for
the other sensors in the range.
The connector is a nine pin D type plug and has pillars for securing the mating connector.
The pillars are tapped with UNC 4-40 threads, standard for this type of connector, but the use
of retaining screws on the mating connector should be avoided unless it can be ascertained
that they contain no magnetic material, which would influence the field at the sensor
elements. Retaining screws commonly contain spring washers or circlips which are
manufactured from ferrous material which render them unsuitable.
3.5 Mag -03MSES - Figure 5
This enclosure is the same as the Mag -03MS but features an environmentally sealed
connector to provide a splash-proof unit. The connector is a rugged, seven way sealed type.
A sealing gasket may be required on the base of the sensor.
3.6 Mag -03MSS - Figure 6
This square section enclosure is designed for marine use and is submersible to depths of 100
metres. The pressure housing is manufactured from polyacetal for minimum water
absorption.
The connector is a seven way marine type and the mating connector is supplied moulded to a
seven way polyurethane jacketed marine cable. The cable is supplied to customer
requirement up to a length of 600 metres.
3.7 Mag -03IE - Figure 7
This sensor has a shortened cylindrical enclosure for the electronics and the three sensing
elements are individually potted and connected to the electronics assembly with flying leads
which have a standard length of 750mm. This allows the user to position the individual
elements independently if required. The sensing elements can be arranged around a sensitive
volume where space is restricted. The connector is the same as for the
Mag -03MC.
3.8 Mag -03IE VERSION 2 - Figure 8
This sensor is identical to the Mag -03IE except that Version 2 has a 5m cable attached with a
25 pin ‘D’ type connector. The bandwidth is increased to 5kHz.
3.9 Mag -03MCTP - Figure 9
This enclosure provides a two part construction. The sensing elements and electronics are
contained in two separate cylindrical enclosures connected by a 1000mm ribbon cable and a
simple eight pin dual in-line socket. The sensing elements are completely encapsulated in
epoxy resin within their enclosure. The external connector is the same as for the
Mag -03MC.
