Midland LMR Announces

New Line Of Advanced

Portable Radios

Midland LMR has introduced a new line of two-way FM portable radios said to be not only smaller but also more rugged and reliable than was economically practical with previous technology. The ad- vanced new portables make exten- sive use of surface-mount technolo- gy, use the small new high-energy batteries and even the lowest-cost models meet MIL SPEC 810C/D, shock and vibration.

Designed for a broad spectrum of users whose needs vary from basic to highly sophisticated, the new

Midland line includes over 30 mod- els, with numerous options, in a wide range of cost/capability levels.

At one end of the scale, for example, are simple, sturdy, economical little 2-watt units with one or two chan- nels and auto-squelch. At the other end of the scale are compact, high- capability Syn-Tech XTR® models with 5 watts, up to 99 channels pro- grammable in groups, both tone and digital squelch, DTFM signaling, priority scan, and optional weather- proof remote speaker/microphone.

All models are available in VHF or

UHF bands.

Saab Marine To Equip

Environmental Tankers —Literature Available "Environmental tankers," as clas- sified by DNV, are now under pro- duction. The first two ships, of

Suezmax size, were recently ordered from Daewoo by Nynas Petroleum of Sweden, and Neste of Finland.

Apart from double bottoms and double skins, reliable cargo han- dling and level gaging are vital to an environmental tanker, and the equipment for these functions is to be supplied by Saab Marine Elec- tronics.

The level gaging system for the nine cargo and two slop tanks on each of the vessels is the proven

Saab TankRadar. Level is detected by means of microwave technology, without contact with the product surface, and with sensors for tem- perature and inert gas pressure con- nected to the TankRadar deck transmitter. The information from the different sensors in multiplexed and transmitted by a single cable to the processor unit, together with information from other transmit- ters. The processor unit also re- ceives input from the electropneu- matic level gaging systems for draft, ballast and fuel, supplied by an out- side contractor. The processing unit is connected online to the load cal- culator.

In itself, this would already be a highly advanced system, but in this case, it has been integrated with the

Saab MaC/501 cargo control sys- tem. Here, the TankRadar pro- cessing unit acts as a substation.

Another substation controls the 11

September, 1990 cargo pumps, two ballast pumps, 44 valves and pump discharge pres- sure, and both are connected to a control room station.

At the top of the hierarchy sits the operator. There are two operat- ing sites. All operations can take place at either of them, and they have been designed according to the latest advances in man/machine communication. All cargo control is undertaken by touching a light pen to a 20-inch color screen. The valves and meters of yesterday's consoles have been replaced by symbols in mimic diagrams on the screen. A touch to any one of the symbols activates it. When a function, e.g., a pump, is active, different parame- ters can easily be set. Built-in safety functions prevent the operator from performing invalid functions and operators are also alerted in the event of a malfunction, e.g., a stuck valve.
