المزايا التقنية الأساسية
-
High-Efficiency Design: The C1 is engineered to meet strict environmental standards. Its steady-state consumption rate is less than 6 scfh, making it compliant with US EPA New Source Performance Standards (NSPS) for the oil and gas industry.
-
Versatile Sensing Elements: Depending on your pressure requirements, the C1 can be outfitted with:
-
Bourdon Tubes: For high-pressure applications.
-
Bellows: For vacuum and low-pressure service.
-
-
Severe Service Readiness: To handle corrosive sour gas environments, constructions are available that comply with NACE MR0175 / ISO15156 and NACE MR0103 metallurgical standards.
-
Operational Reliability: A built-in spring-out cleaning wire allows technicians to clear the relay orifice during operation, preventing shutdowns caused by dirty instrument air.
-
Flexible Mounting: The rugged case is designed for diverse field conditions and can be mounted on a panel, wall, pipestand, or directly onto a control valve actuator.
