Pressure Gauge Calibrator Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14122

The Pressure Gauge Calibrator, often known as a Dead Weight Tester, is critical equipment used to demonstrate the principle of direct calibration for industrial Bourdon tube pressure gauges. Accurate pressure measurement requires proper calibration, and this apparatus allows students to subject a gauge to precisely known pressures for comparison and error analysis.

The apparatus consists of a vertically mounted, precision machined leak proof piston and cylinder assembly (made of stainless steel). The piston has a platform to hold calibrated dead weights. The cylinder is connected to the Bourdon gauge via leak proof valves. By placing different weights on the piston, a known, calculable pressure is exerted on the fluid (water) beneath the piston, which is then transmitted to the gauge. The indicated gauge reading is compared directly to the calculated true pressure for calibration.
