absolute pressure transmitter

INTRODUCTION


The AT3051 Gauge/Absolute Pressure Transmitter is a high-performance industrial pressure transmitter ideal for measuring liquid, gas, or steam flow, as well as liquid level, density, and pressure. It outputs a 4~20mA DC signal that corresponds to the measured pressure, ensuring precise and stable readings. This eexplosion proof pressure transmitter features an advanced sensor that can also measure static pressure, which can be displayed on an integral indicator or monitored remotely through HART communications. With additional features such as quick response time, remote setup via communication protocols, self-diagnostics, and optional status output for high/low pressure alarms, it is a reliable solution for demanding applications. For applications requiring level measurement, the diaphragm type level transmitter option is available, offering flexibility in different settings. Whether you need a vacuum pressure transmitter or an absolute pressure transmitter, the AT3051 provides versatile and accurate monitoring capabilities tailored to industrial environments.

PRODUCT APPLICATION ENVIRONMENTS


  1. Flammable and Explosive Environments
    In settings like oil, chemical, and mining industries, where flammable and explosive materials are present, the explosion proof pressure transmitter is the ideal choice. Designed with explosion-proof housing, it ensures safe operation in hazardous areas and effectively prevents explosion risks caused by equipment or operational sparks.

  2. General Industrial Environments
    For a wide range of industrial applications, such as chemical processing, pharmaceuticals, and water treatment, the industrial pressure transmitter is rugged and durable, handling various media, including liquids, gases, and steam. It provides a stable 4–20mA signal output, facilitating remote monitoring and system integration.

  3. Low-Pressure or Vacuum Environments
    In environments that require negative pressure or vacuum measurements, such as semiconductor manufacturing, vacuum systems, and HVAC applications, the vacuum pressure transmitter ensures accurate measurement and control in low-pressure conditions, meeting the demands for vacuum stability.

  4. High Viscosity or Corrosive Liquid Environments
    In settings like wastewater treatment, slurry transport, and chemical storage tanks, the diaphragm-type level transmitter is ideal due to its corrosion-resistant and anti-clogging diaphragm design. This design effectively prevents scaling and ensures stability in level and density measurements.

  5. Precision Control Environments
    For laboratories, aerospace, and other settings requiring high-precision absolute pressure measurements, the absolute pressure transmitter remains unaffected by external conditions, ensuring long-term stability and high accuracy in vacuum and absolute pressure measurements.
