Purpose
ТЖИУ406D differential pressure transducers and of explosion-proof and non-explosion-proof version are meant for continuous converting of differential pressure of liquids and gases (ranges from 0-6,3 kPa to -02500 kPa), non-aggressive to 12Х18Н10Т steel, unified DC output signal in monitoring and control systems.
Design features
- serially produced, explosion protection certificate received, "1ExdllVT4" explosion-proof markings are available, correspond to GOST 22782.0-81, GOST 22782.6-81, type of explosion protection and explosion-proof according to GOST 22782.6-81;
- according to the degree of protection against dust and water - IP65 according to GOST 14254-80;
- built-in electronic damper of measured pressure ripple;
- overvoltage protection device;
- capability of reconfiguring measurement limits (multi-band version);
- ТЖИУ406 transducer type is registered in the State Register of measuring devices under # 18510-04 and is approved for use in Russia/
