Areas of application

The sensor is designed to measure both absolute and relative pressures in a wide range of temperatures. Pressure sensors manufactured based on the proposed strain gauge transducer can be used in automotive, space, gas and oil industries as well as in general metrology.

Advantages

The use of dielectric isolation makes it possible to increase the range of operating temperature range to 300°C while in conventional sensors with p-n-junction isolation it does not exceed 120°–130°C. Dielectric isolation provides a high time stability of sensor characteristics due to the lack of leakage currents in p-n junctions.

VIBROPROTECTIVE PLATFORM

Theproposedbroprotective platform is intended for vibroprotection of precision equipment andinsulation offacilities subject to vibration.

Field of application– instrument making, aircraft construction, motor-car construction, agricultural and mining machinery, machine building, power engineering industry and transport, namely, manufacturing and modernization of machine-tool stock (including metal-working machinery, presses and grinding machines), optical instruments and fine mechanics equipment (including laser facilities), turbogenerators, trains, etc.

These platforms are provided with elastic elements having adjustable rigidity in the range of infralow frequencies and are characterized by a very high vibroprotection capability. Their inherent frequency of vertical vibrations is 1Hz and they can reduce vibrations 100-1000 times.

Dimension-types of vibroprotective platforms differ depending on the weight of equipment to be protected.

Up to 20kg Up to 50kg Up to 100kg Up to 300kg Up to1500kg

Up to 6000kg

Advantages:

· Equal vibration protection in all directions

· Compatibility with existing equipment in operation

· Ease of operation and control

· Independence from mains supply

Similar platforms can be used to install machinery subject to vibrations in order to reduce intrinsic vibration overloads and to prevent propagation of vibration into the environment.

Low rigidity, non-linear static characteristics and high damping capacity of spring suspension elements make it possible to replace conventional hydraulic dampers with simple and reliable pneumatic ones.
