    High Temperature Pressure Sensor for Steam/Fuel Oil

    5 out of 5 based on 7 reviews | Write a review
    This series of high temperature pressure sensors use a high-performance silicon piezoresistive pressure core as core element. The internal ASICs convert the mV signal into a standard current signal (4-20mA/0-20mA), voltage signal (0-5V/1-5V/0-10V) or RS485. Pressure sensor with stainless steel sealing structure has cooling fins, high anti-vibration and anti-shock performance, measuring range -0.1~100MPa/ -1~1000bar/ -14~14503psi, medium temperature -40~+300℃ (-40~+572℉), for steam/fuel oil/high-temperature liquid pressure measurement.

    Tips: Accuracy of pressure sensor
    Accuracy is an important performance index of pressure sensor, which is an important link on accuracy measurement of whole measuring system. The higher the accuracy of pressure sensor, the more expensive it is. Therefore, as long as the accuracy of pressure sensor can be satisfied the accuracy requirements of the whole measurement system. That will be fine. This allows choosing cheaper and simpler sensors among many ones that serve for the same purpose.
    For some special use occasions, it is unable to choose a suitable sensor in the market. So it is necessary to design and manufacture the sensor by oneself. You can contact us ATO Automation and send us your requirements. We will try our best to produce sensors that can meet your requirements.

    Great quality and value
    It was so worth it. Once off the new one was easy to install. Oil pressure went straight to normal. It's has worked great and I'd recommend this pressure sensor again.

    The pressure sensor is working great on my car
    After my calibration the pressure sensor started working properly, I installed the pressure sensor on my race car a month ago, but so far so good, I give it 5 stars.

    Can this pressure sensor measure 200°C oil?
    Thanks for the information.
    But we could however use these sensor to measure the pressure of the thermal oil, which is limited in temperature to 200°C?
    From: coty | Date: 06/04/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    We recommend that the measured medium is around 200°C, and the sensor needs 7 heat sinks.
    If it exceeds 200°C, we recommend that you use an elbow to dissipate heat.
