A steam pressure gauge can be recalibrated using what tool?

A steam pressure gauge can be recalibrated using a deadweight pressure-gauge tester. This tool provides a reliable method to calibrate pressure gauges, including steam pressure gauges, with high accuracy. The deadweight tester operates by applying known pressures through a set of weights acting on a piston, allowing the user to compare the pressure reading on the gauge with the known applied pressure. This comparison helps to identify any discrepancies and allows for adjustments to be made to ensure accurate readings.

In industrial settings, maintaining precise measurements of steam pressure is critical for safety and operational efficiency, and the deadweight tester is specifically designed for this purpose, making it ideal for recalibrating gauges that measure steam pressure. It provides direct measurement against a standard, which is essential for ensuring that the gauge functions correctly within its specified range.
