Hydrophones are underwater acoustic sensors used in marine research, undersea mapping and navigation, and various commercial and military applications.

Underwater acoustic transducers contain both transmitters and receivers and use distance and directional data for communication, mapping and navigation.

Navigational instruments and avionics include GPS devices, compasses, chronometers, radar units and other instruments for orientation, relative position and absolute position (longitude / latitude).

Fire, police and military equipment is designed for fire, military, security and police applications.

Transportation equipment and parts are used in automotive, marine, aerospace, and rail vehicles.

Collision avoidance sensors use various types of proximity sensors to detect the presence of an object or obstruction.

Inspection services examine products, parts, equipment, repairs, services, installations, and facilities to ensure quality, consistency, and condition, as well as conformance to required standards and/or procedures.

Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.

Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage.

Liquid flow meters are used for measuring the flow or quantity of a moving fluid.

Interface level measurement equipment includes sensors and meters for the detection and measurement of interface levels between different media, such as oil/water interfaces and liquid/solid interfaces.

Litz wires are constructed of individually insulated magnet wires that are either twisted or braided into a uniform pattern to minimize power loss.

Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute.

Volumetric liquid flow switches are devices with a switch output used for measuring the flow or quantity of a moving fluid in terms of a unit of volume per unit time, such as liters per minute. 

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute.
