影響普通壓力開關精度的因素
由于普通壓力開關與電子壓力開關相比，性能普通，不具備眾多的優(yōu)勢，所以比較容易受到某些干擾而影響了測量精度，下面小編就來談談影響普通壓力開關精度的因素都有哪些。
1.當普通壓力開關的工作環(huán)境比較惡劣時，會容易影響其測量精度。比如，高溫低溫環(huán)境、灰塵環(huán)境、電磁場干擾環(huán)境、振動環(huán)境以及潮濕環(huán)境等等，這些惡劣的環(huán)境都會對普通壓力開關帶來不利影響，影響其正常工作。
2.當普通壓力開關的被測介質不符合其使用要求時。如果被測介質中帶有雜質，會對普通壓力開關的元件產(chǎn)生磨損，使開關機構被破壞，最終造成壓力開關的指示值出現(xiàn)誤差。
3.當普通壓力開關測量的壓力存在驟增驟減現(xiàn)象時。這種帶有劇烈波動的壓力會導致壓力開關的指示增大或者減少，出現(xiàn)正誤差，降低了壓力開關的精度。
