$119.68

This series of pressure sensors use a high-performance silicon piezoresistive pressure core as core element. 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. Pressure sensor with stainless steel sealing structure has small size, light weight, high anti-vibration and anti-shock performance, measuring range -0.1~100MPa/ -1~1000bar/ -14~14503psi, medium temperature -40~+60℃ (-40~+140℉), for air/water/oil pressure measurement.

Tips: Stability of pressure sensor
The ability of a pressure sensor to remain unchanged after using a certain time is called stability. In addition to the structure of pressure sensor, the main factors that affect the long-term stability of pressure sensor are the use environment of sensor. Therefore, to make the pressure sensor have good stability, the sensor must have strong adaptability to the environment.
Before selecting a pressure sensor, it is necessary to investigate its use environment, and select the appropriate sensor according to the specific use environment, or take appropriate measures to reduce the impact of the environment.
The stability of pressure sensor has a quantitative index, and it should be calibrated again before use to determine whether the performance of pressure sensor has changed.
In some situations where pressure sensors can be used for a long time and cannot be easily replaced or calibrated, the selected pressure sensor requires more stringent stability and should be able to stand the test for a long time.

Could you provide a image of pressure sensor wiring?

Thank you for the quick response.
I would assume that the pressure in this tube never would even reach close to 100 kPa/1 bar. And if it does, we'll order another one with a greater range. I think I will start with this just to obtain some values.
Are the wiring colors straightforward for the RS 485 version? Could you provide an image that shows an RS485 version of the wires coming out of the sensor?
Apart from that, do you have an average life expectancy number for these sensors?
