WITH MURPHY’S OFF-EQUIPMENT MOUNTING KIT

A solution was recently presented to a customer who had experienced failures with their A20P (Pressure) Swichgage® instruments. The failure, related to the port plate assembly, was the result of high-pressure pulses that compromised the solder joint. When the pressure instrument exhibited characteristics of being fatigued by pulsations in excess of the maximum rated pressure, the plate skirt became fatigued. Repeated pulses resulted in the skirt separating from the solder which caused process fluids to leak into the gauge case.

RECOMMENDED SOLUTION:

We advised our customer to install an Off-Equipment Mounting Kit (#30000213) from Enovation Controls, which is available on the MurCal web store. When they paired their gauge with our pulsation dampening off-equipment mounting kit, the pulsating pressure that caused damage to their gauge was dramatically decreased. 

KIT INCLUDES:

One (1) Stainless Steel Panel (30050782)

Two (2) Shock Mounts with Hardware (65000149)

Two (2) Pulsation Dampeners (PD2160)
