热电偶温度值在二次仪表上显示偏低可能原因及对应处理措施

来源网址:http://www.hztsyb.com/

☆热电极短路                                                                                    ★如潮湿所致,则进行干燥;如绝缘子损坏,则更换绝缘子

☆热电偶的接线柱处积灰,造成短路                                            ★清扫积灰

☆补偿导线线间短路                                                                        ★找出短路点,加强绝缘或更换补偿导线

☆热电偶热电极变质                                                                        ★在长度允许的发问下,剪去变质段重新焊接,或更换新热电偶

☆补偿导线与热电偶极性接反                                                        ★重新接正确

☆补偿导线与热电偶不配套                                                            ★更换相配套的补偿导线

☆热电偶安装位置不录或插入深度不符合要求                            ★重新按规定安装

☆热电偶冷端温度补偿不符合要求                                                ★调整冷端补偿器

☆热电偶与显示仪表不配套                                                            ★更抽热电偶或显示仪表使之相配套

若有其他的热电偶温度值显示偏低请告知我公司,以便我们为在日后生产中做的更好。
