Measuring Devices
Standard
The standard hole gauge is the simplest among measuring devices to quickly determine a diameter. It’s useful for maintenance staff to have one available. This way they can double check the orifices before they are installed in the spray dryer. The reading works basically the same as a caliper.
The standard measuring device is:
- Width range: 0 to 5 mm (mm only)
- Accurate
- Easy to use
Double ended pin gauges
The double ended pin gauge is a simple tool to check if the orifice disc is worn out or not. Each gauge has a GO and a NO-GO side with a 0.02 tolerance. The GO side should fit in the orifice disc, the NO-GO side should not. If the NO-GO side fits, the orifice disc has worn out and needs to be replaced.
For every hole size of the orifice disc, a double ended pin gauge is available. They can be ordered individually and do not need to be purchased in a set of multiple sizes. When ordering the product, please make sure to pick the exact size, even a difference of 0.02 mm will have a negative influence on your spray drying process.
