With the rise in smart watches and navigation systems, absolute pressure sensors find homes wherever elevation above sea level (altimeter measurement) is required. Weather stations also use them for barometric pressure measurements.

How to connect pressure sensor, pressure transducer or pressure transmitter to industrial instrumentation or PLC? ①Pressure sensor 4-wire Millivolt-output ②Pressure transducers 3-wire Voltage-output ③Pressure transmitters 2 wire 4-20mA current-output

How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.

In hydraulic industry, hydraulic oil pressure measurement are critical for monitoring and controlling hydraulic systems, ensuring efficiency, safety, and predictive maintenance.

ORR pressure transmitters applied in the chiller and air conditioning of Carrier and LG which are two most famous air conditioning manufacturer in the world.

Sensors have been widely used in the construction machinery industry. The sensor device can output various physical and chemical signals as electrical signals, such as gravity, temperature, sound, distance, etc., so that the staff can directly control or adjust the data detected by the sensor.

How to select a suitable pressure sensor or transmitter sometimes is a difficult decision. Here are some tips for you. There are six common types of pressure sensor in our market, it's hard to say which one is the best, however, we can select the most suitable one upon our application and practical condition, we can use below table to analyze their different performances and features.

Industrial gas pressure monitoring In order to ensure safe production of storage and transportation of industrial gas, it's essential to acquired pressure value of industrial gas in real time during storage and gas transmission pipeline. ORR pressure transmitter provides pressure monitoring instruments for industrial gas production and storage, ressure measurement enables the automatic monitoring and regulation of gas production equipment and storage cylinders through the auxiliary system to ensure safe production.

It’s difficult to obtain an ideal accuracy if choosing range is not matched actual situation. For example, we don’t suggest use a 1000bar range of pressure sensor on measuring 1bar pressure, it would be better if you could use 10bar range instead of 1000bar. Therefore, choosing the right measurement range​ is very important and efficient for you. Three major factors must to be taken into account:

① Operating Pressure Range: Pressure measuring range the sensor can be safely operated. ② Operating Mode: Absolute pressure, or gauge pressure ③ Maximum Pressure or Burst Pressure: The maximum value of pressure that can be withstood by the sensor without damaging itself. If the applied pressure is more than this maximum pressure value, it might result in device failure or inaccurate signal output, even damage the sensor itself, which named burst pressure. ④ Output Type: It could be Ratio-metric mV, 4~20mA, 0.5Vdc~4.5Vdc, 0~5Vdc, 0~10Vdc, digital I2C and digital SPI. ⑤ Full Scale: Maximum pressure that the sensor can measure from zero pressure. ⑥ Operating Temperature Range: The temperature range the sensor can operate reliably and provide an accurate output signal.
