New York Low Pressure Boiler COF Practice

What is the minimum reading capability of a digital gauge?

1. 1 psi

2. 1/100 of a psig

3. 1/10 of a psig

4. 1/1000 of a psig

The correct answer is: 1/100 of a psig

A digital gauge's minimum reading capability refers to the smallest increment that it can accurately measure and display. In this context, a reading capability of 1/100 of a psig means that the gauge can measure pressure in much smaller increments than one full psi. This precision allows for more accurate monitoring of pressure levels in systems, which is crucial for the safe operation of low pressure boilers. The ability to read in increments of 1/100 of a psig provides operators with detailed insights, helping to prevent potential issues by highlighting slight changes in pressure that might be significant in the context of boiler operations. Being able to observe such fine levels can enhance safety and operational efficiency since even small changes in pressure can be indicative of larger issues that may arise. Therefore, a digital gauge with this capability is essential for maintaining precise control in low pressure boiler systems.
