Since one week my Micro Ion E Gauge (Agilent G3170-80001) has a problem. The indicator-LED keeps switching between green and red. The high vacuum pressure shown on the front-LCD of my 5975C switches between 9.99e+09 Torr and the measured value. The foreline pressure is at a constant and good level.

Looks like the Gauge works fine but not permanently. Any suggestions on how to fix this? Rebooting the system had no impact.

Red light while the system is pumped down indicates a gauge failure.

Green is normal operation.

Yellow is standby, usually this color during initial pump down.

When they fail, the red light is typically solid red, not alternating.

Double check gauge connections to make sure that's not an issue (24V and that the signal cable is going to Serial B connection on Smart Card).

I would say that your gauge is likely failing and needs to be replaced/repaired or it could also be a (less likely) problem with the SmartCard in the electronics module.

JOel is correct in that the active element in the gauge is failing.  When they start to fail they can act in this matter, reporting the 9.9e9 value and a good reading.  The active element in this gauge assembly is replaceable and if purchased from Granville-Phillips runs around $200 as I recall.  If the instrument is under warranty it should be covered.  Email me if you would like assistance in replacing the gauge tube.

Mark,

You listed the Agilent Part # for the assembly in your original post, G3170-80001, the part number for a rebuilt one is G3170-89001.  I would have to call Granville Phillips to get their part number.  You can check them out on the web.

Hidey ho,

Can anybody share the manual for the Micro-Ion gauge head (G3170-80001)?

I bought one on eBay and I'm having trouble finding technical information.  I really need the pinout.

Thanks,

Scott

I believe that you can get the pin-out for the gauge from Granville-Phillips

Thanks Dan,

I sent a request today and hopefully they'll send me the manual.  I've been all over their website and found manuals for every gauge but this one.  Might have something to do with this being an Agilent part.

Hi Dan,

 

My Agilent G3170-80001 ion gauge shows a staedy amber (or is it yellow). As you said the main filamnet can be replaced. Do you know the part number for the filament and from whom can I get it? Agilent does not seel the filaments.

Thanks.

Follow up to my previous post:  I contacted Granville Phillips through their website and they have been very helpful.  An engineer has been helping me with my technical problems and the main salesman for this product called me.

The G3170-80001 is a 354-E (economical) made specifically for Agilent.  Lower accuracy, smaller range, 1 filament (not 2), no degas, greatly reduced command set.

A data sheet shows the pinout but there is no manual for this product.

Hi,

thanks for all the information on this page, that helped me very much to fix our problem with an Agilent G6100 series Quadrupole (G6110A).

Our problem was that the MS status LED turned from blinking orange to red exactly 30 sec after Power on (shortly after hearing a valve moving). High vacuum had shown unrealistic pressure of about 10^-9 to 10^-10 torr.

Agilent offered a replacement of Micro-Ion Gauge (G1960-80303) and AC PCA with Gauge Controller incl. service for about 4000€.

Micro-Ion Gauge (G1960-80303) is a coustom made Granville-Phillips® 355 Micro-Ion® Hot-cathode Bayard-Alpert Ionization Vacuum Gauge (belonging to MKS INSTRUMENTS). Instead of two filaments as given in the mks 355 manual it has only one filament and a shoring bar with the other pin.

The mks service was very helpful and said that there is no repair / filament replacement for 355 gauges and suggested to purchase a new one. To place an order at mks the Agilent Part No. G1960-80303 can be used and resulted in a part price of  less than 300€ (1/3 compared to Agilent).
The replacement can be done easily on the right side of instrument after removing RFPA Box by just removing the two exterior screws. The gauge is fixed with three screws and has a large o-ring that can be reused.

For additional Info: the rough vaccum gauge in G6100 series is a 275 Convectron® Pirani Vacuum Gauge, if you get problems with that part.

Hello All:

 

I need to you advice and help!

 

I have an Agilent 6520 LC-qTOF-MS/MS. The gauge part is Micro-Ion E (Granville-Phllips). Aiglent P/N: G2581-80001. Serial #: G25A1940. It turns red permanently.  Unfortunately, I do not have more than $3000 budget to purchase a new one. Might I ask your kindness to give me some advice? thanks
