PR Electronics 5343B 2-Wire Level Transmitter is designed for converting resistance variations into standard analog current signals, making it ideal for applications involving Ohmic level sensors or valve positions. It offers advanced user-defined linearization and configuration capabilities for precise and reliable measurements.

Applications

  • Resistance to Current Conversion: Converts resistance variations from sensors, such as Ohmic level sensors or valve positions, into standard analog current signals.
  • User-Defined Linearization: Allows the activation of a user-defined linearization function for accurate measurements tailored to specific applications.

Technical Characteristics

  • Quick Programming: The transmitter can be programmed within a few seconds to measure within defined Ohmic values.
  • Data Safety: Continuously checks vital stored data for safety reasons, ensuring reliable operation.
  • Polarity Protection: Protected against polarity reversal to prevent damage and ensure long-term stability.
  • PC Configuration: Configured for specific tasks using a PC, PReset software, and the Loop Link communications interface.
  • PRelevel Configuration Tool: The PReset software includes the PRelevel configuration tool, designed specifically for level applications. This tool provides functions such as “on line” measurement of input span and a linearization function for volume linear output from horizontal cylindrical tanks.

Mounting / Installation

  • Flexible Mounting: Can be mounted in a DIN form B sensor head or on a DIN rail with a special fitting.
  • I.S./Ex Barrier Recommendation: For intrinsic safety (I.S.)/Ex applications, it is recommended to use the 5104B, 5114B, or 5116B as barriers.

PR Electronics 5343B 2-Wire Level Transmitter is an efficient and reliable solution for converting resistance variations into standard analog signals, especially in level measurement and control applications. Its advanced configuration options, robust design, and compatibility with safety barriers make it suitable for a wide range of industrial environments.
