    Overview

    SUCH digital pressure transmitter features a backlit LCD display and supports DC12V, 24V, and DC12-36V power supplies. It can output currents of 4-20mA, voltages of 0-5V/1-5V/0-10V, and RS485 signals. Compact and lightweight, it offers excellent vibration and shock resistance. The pressure sensor measurement range covers -0.1 to 100MPa (-1 to 1000bar/-14 to 14503psi), operating temperature ranges from -40°C to +60°C, frequency response from 5kHz to 650kHz, and IP65 protection, making it suitable for pressure measurement in a variety of working conditions, including hydraulic, oil, and pneumatic pressure.

    Feature

    • Precise measurement: Built-in temperature compensation ensures stable and reliable operation in a variety of environments.
    • Rugged and durable: The integrated cast steel construction is vibration- and shock-resistant, making it suitable for harsh operating conditions.
    • High-grade protection: IP65 protection ensures effective dust and water resistance, extending its service life.
    • Integrated display: High-definition LCD screen provides intuitive readings, eliminating the need for an external display and facilitating on-site monitoring and operation.

    Note: For the output signal RS485, it is only a 485 communication protocol, if you need the data to be received from the PC through the RS485 port, then the PC used should be a PC for industrial application, which can support 485 communication function (such as touch screen HMI upper computer, etc.), A USB to 485 communication interface is also needed to connect the sensor to the PC.

    It supports current signals (4-20mA/0-20mA), voltage signals (0-5V/1-5V/0-10V), and RS485 digital signals, meeting the needs of various control systems.

    ❯

    Not necessarily. Within the sensor's linear range, high sensitivity facilitates signal processing, but excessively high sensitivity can amplify external noise, affecting measurement accuracy. Therefore, a sensor with a high signal-to-noise ratio should be selected.

    ❯

    We recommend choosing a digital pressure sensor with a high signal-to-noise ratio and strong anti-interference capabilities to prevent irrelevant external signals from influencing the measurement results.

    Good digital pressure transmitter, very clear
    Finally got this digital pressure transmitter installed for my setup. The LCD is actually solid, can see the numbers even in the sun which is a win. Accurate too—compared it with my master gauge and it’s spot on. Box showed up a bit beat up, but the sensor was fine. Good buy.
