羅斯蒙特壓力變送器的六種常見故障處理 羅斯蒙特3051壓力變送器的錯(cuò)誤代碼
羅斯蒙特壓力變送器如3051、1151等系列傳感器均是電容式的,將被測壓力、差壓參數(shù)轉(zhuǎn)換成電容的變更,經(jīng)由過程檢測電容的辦法失掉被測壓力或差壓。羅斯蒙特變送用具有穩(wěn)固性好,精度高級(jí)特色,是被普遍采取的儀器。
羅斯蒙特壓力變送器罕見的毛病個(gè)別少數(shù)是由于現(xiàn)場的應(yīng)用或許裝置辦法不當(dāng)所惹起的,經(jīng)由長時(shí)光對市場的考察跟研討,發(fā)明罕見的毛病有如下及類:
1、 羅斯蒙特差壓變送器膜片破壞用什么辦法處置?膜片破壞修了也用未幾,倡議調(diào)換。免得失事故。
2、羅斯蒙特壓力變送器的一次元件比方:孔板、遠(yuǎn)傳丈量討論等梗塞,或裝置情勢錯(cuò)誤,取壓點(diǎn)分歧理。
3、羅斯蒙特壓力變送器的引壓管泄露或梗塞,充液管里有殘存氣體或充氣管里有殘存液體,羅斯蒙特壓力變送器進(jìn)程法蘭存在有堆積物,構(gòu)成丈量逝世區(qū)。
4、 羅斯蒙特壓力變送器接線不準(zhǔn)確,電源電壓過高或過低,唆使表頭與儀表接線端子銜接處打仗不良。
5、不嚴(yán)厲依照羅斯蒙特壓力變送器技巧請求裝置,裝置方法跟現(xiàn)場情況不合乎技巧請求。
6、羅斯蒙特差壓變送器裝反成負(fù)值怎么改正來。羅斯蒙特差壓變送器膜頭前后的討論裝置孔是一樣的,只不外出廠時(shí)只認(rèn)一面裝討論(腰形法蘭),另一面裝排氣螺釘。只要把討論跟排氣螺釘對換一下再裝置就行。別的它的表頭跟膜頭之間也是能夠動(dòng)彈的,松一下緊固螺絲就能轉(zhuǎn)。
以上多少類毛病的呈現(xiàn),都市惹起羅斯蒙特壓力變送器輸出不畸形或丈量禁絕確,防止上述毛病或許處理的辦法就是要仔細(xì)。只有仔細(xì)檢討,嚴(yán)厲依照技巧請求應(yīng)用跟裝置,并實(shí)時(shí)采用無效辦法,羅斯蒙特壓力變送器所碰到的以上成績都能夠消除,消除毛病更輕松。假如現(xiàn)實(shí)出產(chǎn)中碰到其實(shí)不克不及處置的毛病,應(yīng)將羅斯蒙特壓力變送器送到試驗(yàn)室或出產(chǎn)廠家做進(jìn)一步檢討處理。
須要留神的是海內(nèi)當(dāng)初有很多多少家企業(yè)都在販賣羅斯蒙特壓力變送器,在選購時(shí)實(shí)在無論買哪家的,變送器的品質(zhì)都是一樣的。紛歧樣的是售前抉擇適合型號(hào)的才能及售后的處理成績的才能。最幸虧買之前跟他們的販賣技巧上相同一下。免得在羅斯蒙特壓力變送器呈現(xiàn)毛病是無奈失掉實(shí)時(shí)無效的實(shí)時(shí)處理。

Diagnostic Messages , T)
In addition to the output, the LCD meter displays abbreviated operation, error,9 H
and warning messages for troubleshooting the transmitter. Messages appear
according to their priority, with normal operating messages appearing last. To
determine the cause of a message, use a Model 275 HART Communicator to
further interrogate the transmitter. A description of each LCD diagnostic
message follows.
Error$ O!
Error messages appear on the LCD meter display to inform you of serious
problems effecting the operation of the transmitter. The meter displays an"
error message until the error condition is corrected, and the analog output is
driven to the specified alarm level. No other transmitter information is
displayed during an alarm condition
1、FAIL2 r5 l)
The transmitter CPU board and the sensor module are incompatible. If yo
encounter this message, contact Rosemount Customer Central at
800-999-9307 if you need assistance.)
2、Fail Module
The sensor module is disconnected or is malfunctioning. Verify that the
sensor module ribbon cable is connected to the back of the electronics
board. If the ribbon cable is properly connected, there is a problem within2 T- r7 m) R* J# _; o1 L
the sensor module. Possible sources of problems include:
• Pressure or temperature updates are not being received in the sensor
module.! I)
• A non-volatile memory fault that will effect transmitter
operation has been detected in the module by the memory verification
routine.
Some non-volatile memory faults are user-repairable. Use a Model 275
HART Communicator to diagnose the error and determine if it is
repairable. Any error message that ends in “FACTORY” is not repairable
In cases of non user-repairable errors, you must replace the sensor6
module. See “Disassembly Procedures” on page 5-3 or contact
Rosemount Customer Central at 800-999-9307 if you need assistance.
3、Fail Elect
The transmitter electronics board is malfunctioning due to an internal fault.
Some of the FAIL ELECT errors are user-repairable. Use a Model 275
HART Communicator to diagnose the error and determine if it is
repairable. Any error message that ends in “FACTORY” is not repairable..
In cases of non user-repairable errors, you must replace the electronics)
board. See “Disassembly Procedures” on page 5-3 or contact Rosemount
Customer Central at 800-999-9307 if you' w)
need assistance.
4、Fail Config,
A memory fault has been detected in a location that could effect
transmitter operation, and is user-accessible. To correct this problem, use
a Model 275 HART Communicator to interrogate and reconfigure the
appropriate portion of the transmitter memory. Contact Rosemount
Customer Central at 800-999-9307 if you need assistance.
Warnings
Warnings appear on the LCD display to alert you of user-repairable problems
with the transmitter, or current transmitter operations. Warnings appear!
alternately with other transmitter information until the warning condition is
corrected or the transmitter completes the operation that warrants the warning#
message.
1、Press Limit:
The process variable read by the transmitter is outside of the transmitter’s
range.,
2、Temp Limit"
The secondary temperature variable read by the transmitter is outside of
the transmitter’s range.
3、Curr Fixed
The transmitter is in multidrop mode. The analog output is not tracking
pressure changes.
4、Curr Saturd-
The pressure read by the module is outside of the specified range, and the
analog output has been driven to saturation levels.
5、Loop Test
A loop test is in progress. During a loop test or 4–20 mA trim, the analog
output is set to a fixed value. The meter display alternates between the
current selected in milliamps and “LOOP TEST.”
6、Xmtr Info1 h. ~
A non-volatile memory fault has been detected in the transmitter memory
by the memory verification routine. The memory fault is in a location
containing transmitter information. To correct this problem, use a Model9
275 HART Communicator to interrogate and reconfigure the appropriate"
portion of the transmitter memory. This warning does not effect the
transmitter operation. Contact Rosemount Customer Central at1 t
800-999-9307 if you need assistance.
Operation
Normal operation messages appear on the LCD meter to confirm actions or
inform you of transmitter status. Operation messages are displayed with other,
transmitter information, and warrant no action to correct or alter the"
transmitter settings.
1、Zero Pass
The zero value, set with the local zero adjustment button, has been
accepted by the transmitter, and the output should change to 4 mA.
2、Zero Fail
The zero value, set with the local zero adjustment button, exceeds the
maximum rangedown allowed for a particular range, or the pressure
sensed by the transmitter exceeds the sensor limits.6 e
3、Span Pass
The span value, set with the local span adjustment button, has been
accepted by the transmitter, and the output should change to 20 mA
4、Span Fail
The span value, set with the local span adjustment button, exceeds the
maximum rangedown allowed for a particular range, or the pressure;
sensed by the transmitter exceeds the sensor limits.
5、LOCAL DSBLD7 ~7 ?& [. U9 X
This message appears during reranging with the integral zero and span:
buttons and indicates that the transmitter local zero and span adjustments
have been disabled. The adjustments may have been disabled by the
transmitter security jumper on the transmitter circuit board or through
software commands from the Model 275. See “Security (Write Protect)” on
page 2-14 for information on the position of the security jumper and
information on software lockout
6、Write Protect
This message appears if you attempt to change the transmitter
configuration data while the security jumper is in the ON position. See)
“Security (Write Protect)” on page 2-14 for more information about the
security jumper.
以下是相關(guān)網(wǎng)友提問:
1、如何辨別羅斯蒙特壓力/差壓變送器的真?zhèn)危?/strong>
純假的還好辨別的,要是有個(gè)真的對比一眼就看出來了。但是,這種假的很少的。有一種是回收的的東西回去翻新,也就是說一模一樣。跟一樣,這個(gè)很難辨別。只有用了一段時(shí)間才能感覺出來。建議你通過正規(guī)渠道購買,不要一個(gè)勁的找最便宜的,假的還沒有那么泛濫。
2、羅斯蒙特壓力變送器多少錢?
有參數(shù)嗎?最好提供儀表數(shù)據(jù)表,這種都有設(shè)計(jì)院的設(shè)計(jì)數(shù)據(jù)表的,如果是維修的話,提供原來用的壓力變送器的銘牌照片。這樣就會(huì)更準(zhǔn)確。
3、羅斯蒙特壓力變送器測量值比E H壓力變送器高一些?
你這種情況需要拿一個(gè)標(biāo)準(zhǔn)表來檢驗(yàn)到底是那塊表測量值不對,一般智能變送器不會(huì)測量不準(zhǔn)的,你著重檢查設(shè)置上限和下限是否兩塊表是一致的,還有兩塊表的零位是否正常。
4、羅斯蒙特3051d壓力變送器怎么樣?
壓力變送器(pressure transmitter)是指以輸出為標(biāo)準(zhǔn)信號(hào)的壓力傳感器,是一種接受壓力變量按比例轉(zhuǎn)換為標(biāo)準(zhǔn)輸出信號(hào)的儀表。它能將測壓元件傳感器感受到的氣體、液體等物理壓力參數(shù)轉(zhuǎn)變成標(biāo)準(zhǔn)的電信號(hào)(如4~20mADC等),以供給指示報(bào)警儀、記錄儀、調(diào)節(jié)器等二次儀表進(jìn)行測量、指示和過程調(diào)節(jié)。
