Overview:

● Measurement Principle: Static pressure sensing using ceramic capacitive sensors

● Applications: Level detection in open containers

● Versions: Standard (E) and Smart (Z) with HART communication

● Key Features: High sensitivity, long-term stability, strong anti-interference, various structural forms, and materials for industrial use

● Structure Types:

  o ZF-LC Cable-type static pressure level transmitter

  o ZF-LR Rod-type static pressure level transmitter

  o ZF-LD Direct-mount static pressure level transmitter When paired with ZF series digital display controllers, they form a static pressure level measurement and control system. The level transmitter converts the measured level signal into an electrical signal, transmitted to the display controller, which converts and displays the corresponding level value.

● Installation: Multiple installation methods available for user convenience
