Digital Display Pressure Sensors PSAN Series

Product Overview

The PSAN series digital display pressure sensors offer precise and reliable measurement capabilities for various media, including gases, liquids, and oils. These sensors are equipped with an auto shift function that dynamically adjusts the pressure level, ensuring stability and accuracy even when original pressure conditions change. In addition to their measurement capabilities, the PSAN series features several user-friendly functions such as zero-point adjustment, peak value monitoring, and chattering prevention, making them an ideal choice for a wide range of industrial applications.

Key Features

• Versatile Pressure Measurement: The PSAN series can accurately measure pressure in any gas, liquid, or oil, provided the medium does not corrode stainless steel 304/316L.
• Auto Shift Function: Automatically adjusts the pressure level based on external input changes, ensuring consistent and accurate readings.
• Hold Function: Allows users to freeze the current display value or control output for easier monitoring and analysis.
• Forced Output Control: Facilitates device testing and maintenance by enabling forced control of the output, helping to streamline diagnostics and upkeep.
• Easy Installation: The one-touch connector type simplifies wiring and maintenance, reducing setup time and effort.
• Advanced Monitoring Functions: Includes zero-point adjustment, peak value monitoring, and chattering prevention to enhance the sensor's usability and reliability.

Applicable Media and Connection Types

The PSAN series pressure sensors are compatible with a wide range of media:

• Pneumatic Type: Suitable for air and non-corrosive gases.
• Fluid Type: Compatible with non-corrosive gases and fluids that do not affect stainless steel 316L.
• Connection Types: Available in both connector type (Ø 4 mm, 5-core, 2 m) and cable type (Ø 4 mm, 5-core, 3 m) configurations, offering flexibility in installation.

Construction and Durability

• Robust Materials: The sensors are built with a PC front case, a back case made from either PC/PBT+GF15% or PA6, and a pressure port constructed from brass-nickel plated or SUS304/SUS316L stainless steel.
• Protection Standards:
  • Connector type: IP40 (IEC standard)
