Sensor technology gets green light


Approval obtained for pressure sensors in natural gas engines and dual fuel systems for ships.



American Sensor Technologies, Inc. (AST) has obtained American Bureau of Shipping (ABS) approval for several models of pressure sensors used in marine and offshore applications.

The ABS rating certifies that these AST sensors are approved for use on ABS classed vessels. ABS approved pressure sensors from American Sensor Technologies are said to offer distinct advantages and applications for ships, barges, offshore oil platforms and desalination. These include:

• AST4300, AST4310, AST43LP, AST4400, AST4410, AST44LP, AST4600, and AST46HA hazardous location pressure sensors: Operate in hazardous area such as fuel storage, boiler room, engine control units, natural gas engines, dual fuel (natural gas/diesel) systems for ships, power generation and energy management.

• Models AST4500, AST4510, and AST4520 submersible pressure transducers: Ideal for level measurements for water, fuel, wastewater, desalination systems and ballast.

• AST5400 differential pressure sensor: Mainly used for flow and filtration applications in water, fuel, oil and hydraulics.

• AST4000 UL/cUL 508 approved pressure sensor: Main applications include engine room pressure monitoring for oil, coolant and fuel, hydraulics, cranes and desalination equipment.
