All field devices, including the small data acquisition computers and communication system, are certified as intrinsically safe for Class 1 Division 1, Zone 0 installation.
This sensor is mounted in the pressurized section of either a pneumatic or hydraulic actuator and are available in various pressure ratings for optimal scaling.
This sensor monitors the mechanical performance of the valve and actuator. A strain gauge is mounted directly on the yoke and measures dimensional changes by analyzing the amount of force between the valve and the actuator. This type of sensor can also be used to measure torque or thrust.
These sensors are used to detect leaks in the pipe and the sealed cavity compartment of the valve by using two equal dynamic pressure sensors mounted in the upstream, downstream and cavity positions on the valve. The sensor reports the difference in pressure at both locations. The data they collect is then used to confirm seal integrity.
This non-intrusive sensor is mounted on the valve itself on or on the pipe near the valve. When the valve is in the closed position, this acoustic sensor can detect a difference in pressure across the valve, which would indicate a leak.
Product, suppliers, manufacturers and services vary by region. For more information, contact an MRC Global location in your region.
