Основные технические преимущества
-
High-Visibility Monitoring: The 114 mm (4 1/2 inch) white-on-black scale features two red pointers. This high-contrast design provides an instant visual check of both the actual process temperature and how far it has drifted from the set point.
-
Vibration Resistance: By utilizing a low-mass internal design, the 4196 is engineered to withstand the mechanical vibrations common in heavy industrial plants without losing calibration or suffering mechanical failure.
-
Tool-Free Field Adjustments: Maintenance is streamlined because the set point, zero/span for the process pointer, and the switch between direct and reverse action can all be adjusted quickly without specialized tools.
-
Extreme Environment Readiness: The housing is constructed from tough, corrosion-resistant plastic. For specialized applications like natural gas processing, internal constructions are available that comply with NACE standards for sour gas (H2S) service.
-
Pneumatic Efficiency: The refined relay and nozzle design lowers steady-state air consumption to as little as 0.09 normal m3/h (3.5 scfh), reducing the load on plant air systems and lowering operational costs.
