measuring head

A measuring head is the first piece of equipment the wireline comes into contact with off the drum.

A measuring head records tension, depth, and speed.

In less than a second, an "optical measuring head," using a halogen lamp, projects a special pattern onto the foot, recording its dimensions.

The measuring head is composed of several wheels which support the wireline on its way to the winch and they also measure crucial wireline data.

Rather too many people were strutting around measuring heads and saying such-and-such other people were congenitally inferior and dispensable.

For that reason there is a great influence on the measured values, hence great care should be taken that the measuring head is placed on a clean and even sample.

Usually a microwave power meter will consist of a measuring head which contains the actual power sensing element, connected via a cable to the meter proper, which displays the power reading.

What the measuring principles all have in common is the fact that through the evaluation of the sensor signal, geometrical information about the joint and its relative position to the measuring head is provided.

In optical radiometry, sheets made from PTFE are used as measuring heads in spectroradiometers and broadband radiometers (e.g., illuminance meters and UV radiometers) due to its capability to diffuse a transmitting light nearly perfectly.
