Another option that a few manufacturers include is dovetail mounts compatible with those on dial test indicators.
2.
This can be achieved using a dial test indicator, reading deflection at the fastener tail, using a strain gauge, or ultrasonic length measurement.
3.
Modern dial test indicators are usually mounted using either an integrated stem ( on the right of the image ) or by a special clamp that grabs an dovetail on the indicator body.
4.
A " dial test indicator ", also known as a " lever arm test indicator " or " finger indicator ", has a smaller measuring range than a standard dial indicator.
5.
Whereas dial test indicators will give a foreshortened reading if their tips are on an angle to the surface being measured ( cosine error ), a drawing callout of FIM is defined as referring to the distance traveled by the extremity of the tip not by the lesser amount that its lever-like action moves the needle.
