FAQ
What’s the precision pressure transmitter?
Precision pressure transmitters convert pressure into an analog or digital signal, which is proportional to the pressure measured. Precision pressure transmitters are used to monitor and or control sensitive pressure processes. They can also be used as high accuracy transfer standards or as a factory working standard, especially to test or calibrate a variety of pressure measuring instruments. With an accuracy as high as 0.05%FS, these pressure transmitters can be found in laboratories or in production environments where a high degree of precision and accuracy are required.
How to maintain a pressure transmitter?
Apply a calibration sticker on the pressure transmitter with the appropriate calibration due date, and calibrate the pressure transmitter regularly. Clean a transducer with cotton dipped in alcohol.
What is difference between the gauge pressure and absolute pressure?
Basically, gauge pressure is based on the pressure of the atmosphere where the sensor is placed as zero (reference), and absolute pressure is measured from absolute zero, the pressure in a vacuum (approx. 10 Pa or below).
