The aim is to reduce the deviation. Dial Indicators are used in various other applications like comparative measurements, checking parallelism with gauges and fixtures etc. Plunger Dial Gauges are available both in analog and digital models and can be used based on their applications. Let me explain the parts of a plunger Dial Gauge. This is the Cap, Bezel, Pointer, Revolution Counting Device, Stem, Plunger, and Contact Element. There are various types of dials like Continuous Dial, Balanced Dial, Reverse Reading Dial, One Revolution Dials available with 0.01 mm and 0.001 mm. In Measuring Orientations, there are 3 different ways to use the plunger dial gauge. 1) Vertical position, where the contact point faces downward. 2) Lateral position, where the spindle is horizontal. 3) Upside-down position where the Contact point faces upward. If the measurement is performed with the lateral or upside-down position, the measuring force is less than in the vertical position. In this case, be sure to check the operation and repeatability of the indicator or digital display. How to take a reading using an analog plunger Dial Gauge? I have fixed the Plunger Dial Gauge on the Jafuji Dial comparator stand. Rotate the face of the indicator until the "0" marking aligns with the dial. Tighten the knob and then lock the face in position. Let us first see how OD can be measured. This is a 1µ Dial, so every graduation line on the dial is 1µ. There is another smaller needle inside, this denotes the revolution of the bigger needle. Set Zero on the base of the comparator stand. Check for the maximum reading. Here check the revolution counter i.e, the smaller needle reads 5 mm and on the outer Dial reads 20 µ. So, our reading is 5.20 mm Now let us measure the thickness or height of the component. I have slip gauges of various sizes, it shows 2.5 mm, 5 mm, and 10 mm. How to measure the depth of the component using a digital plunger Dial Gauge. Let us take a 10 mm slip gauge and set it to zero. While setting the zero point or pre-setting a specific value, be sure to lift the spindle at least 0.2 mm from the end of the stroke, now the depth of the component can be easily measured. There are some additional accessories that can make our work easier and you can use them as per your application. Optional Accessories 1. Contact Points: This Screw thread is standardized on M2.5 x 0.45 and has a length of 5 mm when we interchange the contact points with different contact elements, then the probe length will be insufficient and might not fix the plunger correctly for its height. This variation can occur during manufacturing. In Mitutoyo there are various types of contact elements available for various applications. Make sure that the right contact element is used and for further information regarding contact elements, kindly contact us. 2. Interchangeable backs: There are various types of interchangeable backs available that can be used for different applications. For Example, Flat Back, Lug-on-centre back, Magnetic Back, Back with offset Lug, etc. 3. Spindle Lifting Lever: The spindle lifting lever is attached to the top end of the spindle for improved inspection efficiency when using a dial indicator mounted on a stand. 4. Spindle Lifting Cable: A Spindle Lifting Cable makes things simpler for the operator, and saves a lot of time. 5. Limit Stickers: These limit stickers are usually stuck onto the dial face or crystal to indicate the tolerance limits and it allows the reader to quickly identify the rejected part. Limit clips can also be used. Disclaimer : Under no circumstances will Bombay Tools Supplying Agency Pvt. Ltd. be responsible or liable in any way for any content.
