SMB-001 Deep C Meter 300 AD Manual
4. LED readout components
The readout unit has three major sub-assemblies: The pressure housing, articulated mount and flying leads.
4.1. Deep C Meter 300 AD™
4.1.1. Pressure housing
- The pressure housing is made from Delrin and is rated for water
depths of 300 meters (1,000 feet).
4.1.2. Lens
- One end of the housing contains an acrylic lens that seals on the pressure housing
with o-rings. Four stainless-steel screws keep the lens seated in the pressure housing. Access
to the inside of the pressure housing is gained by pulling the lens. Removing the lens in the field
should be avoided wherever possible.
4.1.3. Bulkhead connector -
The back end of the pressure housing is sealed with three bulkhead
connectors. These connectors thread into the back of the pressure housing and also seal with
o-rings. It should not be necessary to remove these connectors during normal maintenance. Blank
(dummy) plugs are provided and should be in place whenever the mating connector is removed.
4.1.4. Voltmeter module -
The digital voltmeter module is located within the pressure housing.
The module contains three independent LED displays. Default factory range is ± 2499 mV DC on
the top two display lines. The lower display line is set to ± 199.9mV DC. The meter is powered by
24VDC nominal power but will function between 8-36VDC.
