What is a Pressure Transmitter?

A Pressure Transmitter (TRANSMITTER,PRESSURE) is an instrument that senses, measures and converts pressure of a gas or fluid into electrical signals to be displayed in Pounds per Square Inch (PSI) or the equivalent. The item contains an input pressure port, electrical output connection and may include an output pressure port. See also TRANSDUCER, MOTIONAL PICKUP for items with a linear motional input and electrical output to be displayed in other than PSI or the equivalent.

What is a Pressure Indicator?

A Pressure Indicator (INDICATOR,PRESSURE) is an indicator which indicates the pressure of a gas or liquid in a given system.

What is a Dial Indicating Pressure Gage?

A Dial Indicating Pressure Gage (GAGE,PRESSURE,DIAL INDICATING) is an instrument designed to measure air, gas, fluid, and vapor pressure by means of an internal pressure sensitive element (bellows, bourdon tube, transducer/transmitter and the like) which transmits energy, by direct linkage, to the indicating pointer of a scale or a digital display, calibrated in units of pressure.It may include a temperature equivalent scale.For items that do not have an internal pressure sensitive element see INDICATOR, PRESSURE.

What is an Electrical Tachometer Indicator?

An Electrical Tachometer Indicator (INDICATOR,ELECTRICAL TACHOMETER) is an instrument which displays, in units of revolutions per minute, the transmitted rotational speed of a shaft for a specified elapsed time.

What is a Rate Of Flow Indicator?

A Rate Of Flow Indicator (INDICATOR,RATE OF FLOW) is an indicator which indicates the rate of flow of a fluid.

What is a Torquemeter Indicator?

A Torquemeter Indicator (INDICATOR,TORQUEMETER) is an electrically operated instrument that indicates the torque output of an engine. It functions similarly to an ammeter, but is calibrated in terms of horsepower based on revolutions per minute.

NATO Supply Class 6620 is a classification within NATO Supply Group 66, which is dedicated to Instruments and Laboratory Equipment. Specifically, Class 6620 focuses on Engine Instruments.

Engine Instruments are devices used to monitor and measure various parameters and performance indicators of engines. These instruments play a crucial role in ensuring the efficient and safe operation of engines in various applications, including automotive, aerospace, marine, and industrial sectors.

Some examples of Engine Instruments that fall under NATO Supply Class 6620 include:

1. Tachometers: These instruments measure the rotational speed (RPM) of an engine's crankshaft. They provide valuable information about the engine's performance and help in monitoring and controlling its speed.

2. Pressure Gauges: These instruments measure the pressure of fluids, such as oil, fuel, or coolant, within an engine. They help in monitoring the engine's oil pressure, fuel pressure, and coolant pressure, ensuring proper lubrication and cooling.

3. Temperature Gauges: These instruments measure the temperature of engine components, such as coolant temperature, oil temperature, or exhaust gas temperature. They help in monitoring the engine's operating temperature and prevent overheating or other temperature-related issues.

4. Fuel Flow Meters: These instruments measure the rate of fuel consumption in an engine. They provide valuable information about fuel efficiency and help in optimizing fuel consumption.

5. Oil Pressure Switches: These instruments monitor the oil pressure within an engine and provide an electrical signal if the pressure falls below a certain threshold. This helps in detecting oil pressure issues and preventing engine damage.

6. Engine Hour Meters: These instruments measure the total running time of an engine. They are used for maintenance purposes, as they help in scheduling regular maintenance and tracking the engine's usage.

These are just a few examples of Engine Instruments covered under NATO Supply Class 6620. The class encompasses a wide range of instruments used for monitoring and controlling various aspects of engine performance.
