Critical Technical Advantages
-
Hygienic Design Integrity: The PTP33B is engineered with flush-mounted process connections to prevent media entrapment and bacterial growth. Its certifications (3-A, EHEDG) and materials (FDA, EC 1935/2004) ensure it meets the strictest sanitary standards.
-
CIP/SIP Compatibility: The switch is built to withstand rigorous Clean-In-Place (CIP) and Steam-In-Place (SIP) cycles. It can endure sterilization temperatures up to 135°C (275°F) for one hour without compromising the sensor’s integrity or accuracy.
-
IO-Link Connectivity: As a smart device, the PTP33B supports IO-Link, which allows for remote parameterization and seamless integration into industrial fieldbus systems. This reduces commissioning time and enables advanced diagnostics.
-
Integrated Switching & Display: The device includes local switching electronics, a bright digital display, and status LEDs. This allows operators to monitor pressure and switch status directly at the process line, facilitating decentralized control.
-
Robust and Overload Resistant: Despite its compact size, the piezoresistive metal sensor is extremely stable and resistant to pressure spikes, ensuring high process availability even in dynamic systems.
-
Efficient Installation: The compact design and variety of small hygienic connections make it ideal for installation on narrow skids, filling machines, and small process vessels.
