  • Introduction

The anti-corrosion pressure transmitter uses a ceramic piezoresistive pressure sensor, which converts the pressure of the measured medium into a standard electrical signal through a high-reliability amplifier circuit and precise temperature compensation. The high-quality sensor and perfect assembly process ensure that the product excellent quality and performance. This product is made of polytetrafluoroethylene and has good corrosion resistance. It is mainly used in the chemical industry, especially for pressure measurement of corrosive media such as acids and alkalis.

An anti-corrosion pressure transmitter is a type of pressure sensing device designed to resist and protect against the damaging effects of corrosion in harsh and corrosive environments. Corrosion is a natural process that can occur when certain materials are exposed to moisture, chemicals, or other corrosive agents, leading to the degradation of the material and potentially affecting the performance and accuracy of pressure transmitters.

Features of an Anti-corrosion Pressure Transmitter:

1. Corrosion-Resistant Materials: These transmitters are typically made from corrosion-resistant materials such as stainless steel, titanium, or specialized alloys that can withstand the corrosive effects of the surrounding environment.

2. Sealed Enclosures: Anti-corrosion pressure transmitters come with tightly sealed enclosures or protective coatings to prevent the entry of moisture or corrosive substances into sensitive internal components.

3. Chemical Compatibility: They are designed to be compatible with a wide range of corrosive chemicals commonly encountered in various industrial processes.

4. Robust Construction: The transmitters are built to be durable and resilient, ensuring long-term reliability and accurate pressure measurements in corrosive environments.

5. Wide Pressure Range: These transmitters are often capable of measuring pressures across a broad range, making them suitable for diverse applications.


Anti-corrosion pressure transmitters find applications in industries and environments where corrosion is a significant concern, including:

1. Chemical Processing: In chemical plants, where corrosive substances are handled, these transmitters are vital for monitoring and controlling pressure.

2. Marine and Offshore: On ships, offshore platforms, and coastal installations, where exposure to saltwater and harsh atmospheric conditions can cause corrosion.

3. Water and Wastewater Treatment: In facilities dealing with corrosive chemicals in water treatment processes.

4. Oil & Gas: In oil and gas exploration, production, and refining processes, where corrosive elements are present.

5. Mining: In mining operations where the presence of acidic or alkaline substances can lead to corrosion.

6. Pharmaceutical and Biotechnology: In facilities where corrosive cleaning agents or chemicals are used.

It's essential to select the right anti-corrosion pressure transmitter based on the specific requirements of the application, including the type of corrosive substances present, the temperature range, and the pressure levels involved. Proper maintenance and periodic inspection are also crucial to ensure the continued effectiveness of the transmitter in corrosive environments.
