Model 1518 Diaphragm Differential Pressure Gauge
The Orange Research Model 1518 DP Diaphragm Gauge is a reliable and versatile instrument engineered for measuring differential pressure in both liquid and gas applications. Featuring a zero-center compound range, it is ideal for systems where the differential pressure can fluctuate in both positive and negative directions. Built to handle line pressures up to 1,500 psig, this model provides safe and dependable performance. It is available in several configurations to suit your specific needs: a gauge-only version for visual monitoring, a gauge-switch combination for both local indication and system control, and a switch-only version for straightforward process automation.
Features
-
High pressure capability: Withstands line pressures up to 1,500 psig.
-
Zero-center compound range: Ideal for fluctuating differential pressure.
-
Multiple configurations: Available in gauge-only, gauge-switch combo, and switch-only versions.
-
Durable construction: Engineered for reliable operation in challenging industrial settings.
-
For liquids and gases: Specifically designed for use with both liquid and gas media.
