SALINITY INDICATING EQUIPMENT
|Publication Date:||16 March 1988|
This specification covers salinity indicating equipment consisting of multi-channel consoles and sensors. Multi-channel consoles provide for individual salinity channel modules, individual visual alarms, a common meter, and a common audible alarm. These consoles have the ability to actuate externally-operated dump valves, indicators, and alarms. Consoles employ temperature compensated salinity sensors.
The console type designation shall be in the following form as specified (see 6.2.1):
IC/SB 15 B 3D 005M 8 Equipment Salinity Console Dump valve Maximum Salinity (see 1.2.1) channel type circuits indication modules module (see 1.2.3) (see 1.2.4) and scale provided capacity units (see (see (see 1.2.2) 1.2.5) 1.2.6)
Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Sea Systems Command, SEA 55Z3, Department of the Navy, Washington, DC 20362-5101 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.
The equipment shall be identified by the four-letter symbol "IC/SB" which denotes that the equipment is part of the interior communication (IC) system, salinity indicating circuit (SB).
A number denotes the maximum number of salinity channel modules that can be accommodated by the console. Consoles shall be available in capacities of 1, 7, and 15 channels for the basic console and 7 and 15 channels for the repeater console.
A single letter denotes the console type as follows:
B - Basic console. R - Repeater console (see 3.10.1). M - Dual meter console (see 3.10.2).
This designation, consisting of one digit and the letter D, denotes the number of dump valve control circuits provided. The possible designations are 3D, 2D, 1D, and 0D (0D signifying that there is no dump capability provided).
This designation, as shown below, denotes the maximum range of the transmitter or meter readout and the scale units. Scale units are indicated by M (microsiemens per centimeter (µS/cm)) and P (parts per million (p/m) of chloride). Standard ranges shall be as follows:
005M 0 to 5 µS/cm 050M 0 to 50 µS/cm 010P 0 to 10 p/m of chloride 02500M 0 to 2500 µS/cm 005M/050M Dual meter console; 0 to 5 µS/cm and 0 to 50 µS/cm
Meters for applications requiring other than the standard meter scales shall be approved by NAVSEA. An "S" following the scale unit designation shall indicate a special meter requirement.
This number denotes the actual number of salinity channel modules provided.
An "S" following the number of salinity modules provided shall indicate a special console requirement.
The salinity sensor type designation shall be in the following form:
IC/SB 1 10 Identification Material Sensor constant (see 1.3.1) (see 1.3.2) (see 1.3.3)
The salinity sensor shall be identified by the four letters "IC/SB" denoting interior communication salinity indicating circuits.
This designation shall indicate the material of the sensor as follows:
1 - Brass. 2 - Corrosion-resistant steel.
This designation shall indicate the sensor constant as follows:
No designation - 0.1/cm 5 - 5.0/cm 10 - 10.0/cm

The salinity indicating equipment covered by this specification is intended for naval shipboard use for detecting and indicating the amount of dissolved salts in systems such as propulsion condensate, fresh water distillate, cooling water, and others. The equipment is in each case a semi-vital unit which, if disabled, would impair the effectiveness of the ship.View Less
