Model 1204 Explosion Proof Differential Pressure Gauge
The Orange Research Model 1204 DP Piston Gauge is a versatile and robust instrument engineered for measuring differential pressure in liquid applications within hazardous environments. It is designed to withstand line pressures up to 6,000 psig, ensuring reliable and safe performance. This model is Class 1, Div. 1 rated, making it suitable for use in locations where flammable gases or vapors may be present. It is available in several configurations to meet your needs: a gauge-switch combination for local indication and system control, a switch-only version for process automation, a transmitter-only version for remote monitoring, and a gauge-transmitter combination for both local display and remote data transmission.
Features
-
High pressure capability: Withstands line pressures up to 6,000 psig.
-
Multiple configurations: Available in gauge-switch combo, switch-only, transmitter-only, and gauge-transmitter versions.
-
Class 1, Div. 1 rated: Safe for use in hazardous locations.
-
Durable construction: Engineered for reliable operation in challenging industrial settings.
-
For liquids: Specifically designed for use with liquid media.
