Model 1201 Differential Pressure Gauge
The Orange Research Model 1201 DP Piston Gauge is a versatile and robust instrument engineered for measuring differential pressure in liquid applications. It is designed to withstand line pressures up to 3,000 psig, ensuring reliable and safe performance in demanding environments. This model is a popular choice for use in filtration, hydraulics, and heat exchanger systems. It is available in several configurations to meet your 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 3,000 psig.
-
Multiple configurations: Available in gauge-only, gauge-switch combo, and switch-only versions.
-
Durable construction: Engineered for reliable operation in industrial settings.
-
Versatile applications: Commonly used in filtration, hydraulics, and heat exchangers.
-
For liquids: Specifically designed for use with liquid media.
