Pressure Gauge

ISEN Low Pressure Diaphragm Gauge is a mechanical pressure measuring instrument designed for applications where accurate measurement of relatively low pressure is required. Instead of using a conventional Bourdon tube, the gauge uses a single beryllium-copper diaphragm to detect pressure changes and convert them into pointer movement on an analog dial. The gauge features a 2½-inch dial, black-finished drawn steel case, polycarbonate lens, aluminum dial, brass movement, and brass socket. Its specified accuracy is ±1.5% of full scale, exceeding ASME B40.100 Grade B requirements.
