TPH
TRANSDUCER FOR HIGH PRESSURE
Main features
• Ranges: from: 0...1000 to 0...5000 bar
• Accuracy: ± 0.1% FSO typical
• Protection: IP65/IP67
• Internal calibration signal
• Wetted parts: 15-5PH / 17-4PH stainless steel
• Operating temperature: -30...+120°C
• Measurement diaphragm with monolithic stainless steel
structure
• Suitable for measuring static and dynamic pressure *
Series TPH transducers for high pressure are based on the extensimetric measurement principle with strain gauge on stainless steel.
The measurement diaphragm with monolithic structure makes the
transmitter highly efficient, reliable, and safe – extremely important
factors in high-pressure applications.
The entire mechanical structure, with vent holes, is designed to
guarantee safety and makes the transducer suitable for measuring
both static and dynamic pressure, even under harsh conditions.
The TPH is particularly suitable for applications in high and very high pressure hydraulic circuits, such as (for example) on test benches
or on waterjet cutting machines. State of the art components and high precision machining make the TPH the ideal product for all above
requirements, where is needed the non-amplified transducer with mV/V output.

MECHANICAL DIMENSIONS – Process connections – Detail of conical seal
In high pressure applications, safety of the process connection is guaranteed entirely by the conical seal (metal on metal).
The series TPH offers two types of female connections, F250-C (D) and
M16x1.5 (E), both with 60° conical seals (see drawing for mechanical
details).
