April 11, 2014 - The PR 5343 sensor head-mounted 2-wire level transmitter has FM, IECEx and INMETRO approvals, clearing the way for its use in hazardous area applications in the factory and process automation industry in USA, Brazil and a number of other countries. The 5343 is a sensor head-mounted 2-wire programmable level transmitter with high measurement accuracy suitable for measuring liquid levels in a wide range of industry processes. The transmitter can take in potentiometer signals from reed switch chains, which are used for measuring liquid levels – for instance, in a tank.
This application is suitable for almost all liquids as it provides a constant indication of liquid level regardless of the presence of foam or changes in the dielectric number, conductivity, pressure, or temperature. The transmitter is available in two versions: 5343A and 5343B – both ATEX and DNV Marine approved. In addition, the “A” version has received IECEx and INMETRO certification for Zone 2 whereas the “B” version has received both IECEx, INMETRO, and FM certification for Zone 0 / Division 1 installation.
