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.

Existing reviews of High Temperature Pressure Sensor for Steam/Fuel Oil

How the sensor determines gauge pressure

We own a few of the high temperature pressure sensors for steam/fuel oil, configured to read gauge pressure between -1 to 3 bar. We are currently troubleshooting and were wondering how the sensor determines gauge pressure. Does the sensor have a zero-value of standard atmospheric pressure at sea level (i.e., 1 bar abs)? Or, does the sensor zero itself based on the local atmospheric pressure? Since the pressure in Albuquerque is about 18% less than at sea level, we are reading 0 bar gauge when open to the atmosphere, when we were expecting to read something like -0.18 bar. This is fine if so, we just want to confirm so we set up our measurements correctly. I just want to know how the sensors determine the zero-level for pressure. Is it a fixed value (i.e., 1 bar abs) or is it based off of local pressure (i.e., less than sea level at higher elevations).
