Flush Diaphragm Pressure Transmitter

Pressure Transmitter

Flush Diaphragm Pressure Transmitter

MODEL: ZNC-PT-FD

The Flush Diaphragm Pressure Transmitter is specifically engineered for processes involving viscous, corrosive, crystallising, or slurry-like media where conventional pressure ports would easily clog or contaminate the process. Unlike standard transmitters, this design features a pressure-sensing diaphragm that is absolutely flush with the process connection. This eliminates any cavities, corners, or dead zones that could trap media. This core characteristic makes it the ideal solution for sanitary and highly viscous applications.

Description

Overview of Flush Diaphragm Pressure Transmitter

Our Flush Diaphragm Transmitter (hereinafter referred to as the product) is a specialized pressure measuring instrument designed for processes with high hygiene standards or media prone to clogging.

What is our Flush Diaphragm Transmitter, and what are its main application fields?

Product Definition: The product is a high-accuracy pressure transmitter featuring a flush-mounted diaphragm that is completely level with the process connection. This design eliminates cavities where media can accumulate, ensuring a clog-free and residue-free measurement.
Main Application Fields:

Food and Beverage Industry: Measuring pressure of viscous liquids, slurries, and pastes (e.g., chocolate, sauces, yogurt).
Pharmaceutical and Biotechnology: Monitoring pressure in sterile processes, fermenters, and filtration systems compliant with CIP/SIP requirements.
Pulp and Paper/Wastewater: Applications involving high-solids media and sludges prone to crystallization or buildup.

What are its key features?

Our Flush Diaphragm Transmitter is defined by its hygiene, reliability, and anti-clogging properties:
Hygienic Design: Eliminates dead zones and minimizes the risk of bacterial contamination.
Easy Cleaning: Compatible with fast and thorough Clean-In-Place (CIP) and Sterilization-In-Place (SIP) systems.
Clogging Prevention: Ideal for handling high-viscosity and high-solids media.

Features of Our Flush Diaphragm Transmitter

Summary of product selling points:

Supreme Hygienic Compliance: Flush diaphragm prevents media buildup, perfectly supporting CIP/SIP cycles and sanitary regulations.
Clog-Free Operation: Ensures continuous, reliable measurement even with viscous fluids, pastes, or media containing particulates.
Wide Connection Compatibility: Available with industry-standard hygienic connections, such as Tri-Clamp and flush flanges.
Robust Construction: All stainless steel wetted parts (e.g., 316L) ensure chemical compatibility and long service life.

Applications of Our Flush Diaphragm Transmitter

Description of product applications.

Our Flush Diaphragm Transmitter is essential for maintaining product quality and operational efficiency:

Viscous Fluid Monitoring: Measuring the pressure of thick media that would instantly clog standard transmitters with recessed ports.
Sterile Tank Level and Pressure: Used in mixing and storage tanks in pharmaceutical and food production to ensure no contamination.
Filtration System Monitoring: Measuring upstream pressure in filtration processes handling sludge or high-solid content.
Hygienic Process Control: Integrated into control loops for ensuring precise pressure application during homogenization and filling.
