How to effectively improve the anti-interference ability of pressure transmitter right? Release date: 2019 04 - 25 viewed: zero

Pressure transmitter is a kind of pneumatic signal or convert pressure into electrical signals to control devices and remote transmission. It can load cell sensor detects the physical pressure parameters such as gas and liquid into a standard electrical signals ( Such as 4 ~ 20 madc) 。 ) Provide for measuring, instructions and process adjustment of auxiliary equipment, such as indicator alarm, recorder, and regulators. 1, the pressure transmitter output signal choice: pressure transmitter output signal consists of millivolts, ma and digital output, output signal is commonly used for 4 - 20 ma, etc. When pressure transmitter when used under severe interference, the choice of the output signal is generally adopt frequency output method or ma output method. In addition, under special conditions for the use of pressure transmitter, besides considering the output signal, also need to install the filter in the pressure transmitter or take special protective measures, in order to improve the anti-interference ability of the pressure transmitter. 2. Packing: selecting pressure transmitter, pressure transmitter working conditions, such as what is contact medium, air condition, etc. , should be fully considered. In order to reduce the use of pressure transmitter failure, must be correct packing pressure transmitter. 3, the stability of the transmitter: many pressure transmitter will appear after the timeout to use 'drift' phenomenon. Effectively reduce use of solution of the problem is to consider when choosing pressure transmitter stability. 4, pressure transmitter, the connection of the distance and connection mode: for pressure transmitter, pressure transmitter and other equipment the connection between the distance and the length of the connecting method will affect the anti-jamming performance of a transducer.
