High pressure transducers are engineers tools for utilitarian purposes and making things more Utopian in this impatient and fast developing world. Transducers provide proper mechanical equipment for completing a work. Here I provide a little information on this topic.

3. High-Wire Pressure Transducers
• High wire pressure transducer is basically
used for High pressure measurement
• Usually pressure is above 1000atm, special
techniques have to be used this technique is
work on the properties of material
• It is passive transducer that means it requires
external power to operation

4. Basic Principal
• In this technique is based on the Electrical
Resistance change of a Manganin (alloy of Cu, Mn
,Ni) or Gold Chrome wire , with Hydrostatic
Pressure, due to Bulk Compression effect
• In this device the Coil is enclosed in a flexible
bellows Filled with Kerosene , for transmitting the
pressure to be measured to the coil
• The change of resistance between the wire A and
B can be made part of a bridge circuit to measure
resistance between the coil and indirectly the
measurement of pressure

5. Factors for changing Electrical resistance and
Sensitivity Expression:-
• Changing the Diameter (D):Wire which is used to
measure pressure or electrical resistance depend on
diameter
• Changing the length (L) which also effect the electrical
resistance in the wire
• Changing the resistive constant (ᵨ)also effect the
electrical resistance and also to sensitivity expression

6. Types
• Manganin ,high wire pressure transducer with the Sensitivity is
2.5x10^(-11)
• Gold-chrome ,high wire pressure transducer with the Sensitivity is
9.85x10^(-12) it is less sensitive it is preferred to manganin

7. Specification Sheet

8. Advantages Dis-advantages
1)With stand virtually any 1)Are often expansive
Environment 2)Usually difficult to find
2)Easily can be connected to 3)Highly temperature sensitive
Any systems
3)Highly sensitive
4)Static pressure measurement
5)Capability
6)Repatibility

9. Applications
• This transducer are useful in any industry with strict manufacturing or processing
requirements ,such as food and drink ,pharmaceuticals or electronics
• They can be used in refrigeration systems ,robotics and automation ,HVAC and in
systems ,to protect any environment with sensitivity to pressure fluctuations
• Leak testing :A pressure sensor may be used to sense the decay of pressure due to a
system leak. This is commonly done by means of utilizing the pressure sensor to
measure pressure change over time

10. Conclusion
• General purpose of pressure transducer are the most common since they are
designed to fit the broadcast set of application .By using the transducers we
measure various ranging pressure . Transducers made easy operation of
measuring pressure or also work make fast and its several application helps in
industrial work
