    5 out of 5 based on 2 reviews | Write a review
    High temperature pressure transducer with classic 2088 type head can be used in humid or harsh environment for a long time. Pressure transducer has optional measuring range -0.1~60MPa/ -1~600bar/ -14~8702psi, medium temperature -20~+300℃ (-4~+572℉), special for air/water/oil pressure measurement. The internal ASICs convert the mV signal into a standard current (4-20mA/0-20mA), voltage (0-5V/1-5V/0-10V) or RS485 signal.

    Tips: Outage and commissioning steps of on-site installed pressure transducer
    The installation method of on-site installed pressure transducer and spring manometer are nearly the same, namely there's only one sampling valve. Sometimes, there's also a drain valve.
    Note: On-site installed pressure transducer mentioned here mainly refers to the screw mounted transducer, such as the monocrystalline silicon pressure transducer.

    1. Outage Method of On-site Installed Pressure Transducer
      When stopping, close the sampling valve of on-site installed pressure transducer and open the drain valve slowly to remove the measured pressure. If there's no drain pressure, the pressure can only be relieved by slowly loosening the joint threads of pressure transmitter. When operating, be careful of medium pressure injury.
    2. Commissioning Method of On-site Installed Pressure Transducer
      When commissioning, open the sampling valve of on-site installed pressure transducer.

    Existing reviews of High Temperature Pressure Transducer, 100/300/3000/5000 PSI
    Convenient High Temperature Pressure Sensor
    I use this high-temperature pressure sensor to check the engine. It takes a lot of time for our auto repair shop to check the engine of the vehicle sent for repair, and we often make mistakes. The pressure values such as intake manifold pressure, exhaust pressure, turbocharger pressure, etc. are all important for the engine. Anyway, I have a question concerning the Pressure Transducers. Is 10Hz (1 data point every 0.1s) a good sampling rate to acquire data? There doesn't seem to be any mention of the sampling rate on the spec sheet.

    ATO Responded
    The response time of the pressure sensor is expected to be about 1 ms, which is close to the real-time display value.
    Related questions about high temperature pressure transducer
    I want ask you can I connet the pressure sensore output RS485 directly with pc by used cable RS485 converter, also can I connect 4 sensor to the computer in the same time?
    From: Mephod | Date: 13/05/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes. First, all four sensors and PC (such as touch screens) must support RS485 communication protocol.

    High Temperature Pressure Sensor for Steam/Fuel Oil

    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.
