The HPM3189 High Temperature Differential Pressure Transmitter utilizes an imported pressure core designed to withstand high temperatures as the sensitive component. This core converts the pressure of the measured medium into a signal through the heat radiation structure of the transmitter. Housed in a stainless steel shell, the signal circuit with minimal temperature drift translates the transmitter signal into a standard current output, allowing direct connection with computers, control instruments, and display devices. Featuring an integrated stainless steel structure, this product offers outstanding functionality, easy installation, impact resistance, and vibration resistance. The high temperature-resistant core and heat radiation design ensure its long-term suitability for high temperature media applications.


  • Utilizes high-temperature resistant imported differential pressure core.

  • Suitable for a broad range of medium temperatures.

  • Features IP65-rated ingress protection.

  • Equipped with polarity reversal, overcurrent, and overvoltage protection, meeting EMI requirements.

  • Resistant to impact, vibration, and corrosion.
