Features

• Metal-thin film sensing technology, which consists of a metal-thin film resistor bridge on an Elgiloy® diaphragm, enables PTU series pressure transducers to maintain reliable readings over a wide range of temperatures.
• Modular construction and configurable, renewable electronics that enable interchangeability of internal components provide flexibility, reduce inventory, and make any required maintenance quick and simple.
• All wetted components are 316L VIM-VAR stainless steel and Elgiloy to promote corrosion resistance and clean operation.
• Standard transducer enclosure meets Ingress Protection IP65/NEMA4 or IP54/NEMA3.
• Genuine VCR face seal fittings

Testing
Every Swagelok PTU series pressure transducer is factory inboard vacuum tested with helium to a maximum leak rate of 2 × 10–9 std cm³/s.

Calibration
Every Swagelok PTU series pressure transducer receives a five-point pressure calibration to ensure proper operation over the designated pressure range. A certificate of calibration is supplied with each transducer.

Cleaning and Packaging
Every Swagelok PTU series pressure transducer is assembled, cleaned, and packaged in a Class 100 cleanroom.

Options

• Digital display indicator with two programmable switching points, user-configurable units, and front or top view
• 13-point pressure calibration traceable to Deutscher Kalibreirdienst (DKD), German Calibration Service
• Typical material certification (part number and purchase order number specific)
• Material Mill 3.1B Certification
