重要な技術的利点
-
High-Pressure Overload Resistance: The metallic sensor is engineered to be exceptionally robust, handling process pressures up to 400 bar (6,000 psi). This protects the instrument against sudden pressure spikes that might damage more sensitive ceramic membranes.
-
IO-Link Connectivity: As an IO-Link capable device, the PTP31B offers seamless integration into automation systems. This enables fast, software-based parameterization and provides enhanced diagnostic data, significantly reducing commissioning time and costs.
-
Local Visibility and Control: The integrated digital display and bright status LEDs provide immediate feedback on the process state. Operators can check the current pressure or switching status at a glance without needing to access a central control room.
-
Decentralized Automation: With integrated switching electronics, the PTP31B can manage local control loops independently. This economic approach allows for direct control of valves or pumps, simplifying the overall system architecture.
-
Flush-Mounted Options: The availability of small, flush-mounted process connections makes this switch suitable for applications where media build-up or clogging must be avoided.
-
Versatile Operation: The PTP31B is designed to operate in a wide temperature range (-40 to +100°C) and is certified for use in dust-hazardous areas, ensuring reliable performance in diverse industrial environments.
