Measurement pressure transducers VPTA Collective research-and-production company "MAGNOV" offers measuring transducers of pressure (MTP) of own development with a limit of an basic error ± 0,25 (± 0,4; ± 0,5) % for petrochemical, chemical, petro-gas-obtaining, oil refining and other enterprises and productions. If necessary MTP can be produced with the basic error 0,1 and 0,15 % and additional temperature error no more than 0,1 %/ îÑ (It’s not depended on a class of precision).
MPT serve for transformation of pressure of gases (air), steams, liquids in noise-resistant analog unified electrical output signals of a direct current 4-20 mÀ.
MPT are intended for work in systems of automated monitoring and regulation of productions in any industries.
MPT have a modular construction, possibility to control of efficiency, turning ("ZERO" and "RANGE").
In a complete with a barrier spark-security MPT are used in explosive mediums, kind of explosion-proof construction – spark-security electrical circuit, level of explosive-security «ÎÅõ³à²²ÂÒ4».
MPT are maintainabilited without restrictions.
MPT have the climatic design with splash-proof, dust-tight, vibration-steady and non-corrosion constructions.

MPT
are a replacement of gauges of a type "SAPPHIRE", "PIEZO-TRAN" and other
measuring transducers of overpressure of a similar class of precision.
MPT are executed on the basis
of a differential capacity converter ensuring high stability of the indications
in time, that allows to expand an utilisation on a comparison with gauges
have semiconducting tensoresistors.
High precision of MPT are ensured
with properties of a precision alloy 36ÍÕÒÞ, effective electronic system
of a linearization of characteristic and built-in cannel of temperature
compensation, decreasing a temperature error.
For mechanical deleting of deposits
and adjournment of products of a medium on a surface of a diaphragm in
a working nappe of MPT the possibility of disassembly of a receiving
knot of the gauge is stipulated.
