Narrative:
While at cruise at FL350, the left engine's oil pressure indicating pointer dropped to zero psi. This indication did not trigger either a master warning flasher, or a red indicator light on the caution warning panel. This combination of indications caused me to suspect a failed oil pressure transmitting device, rather than an actual loss of oil pressure. Once starting the appropriate checklist, we contacted company maintenance control to confer. Maintenance control advised to follow the checklist. Upon completion of checklist, which resulted in securing the left engine, it was determined that txk airport was the closest suitable airport to divert to. ZME was advised of our situation and request for deviation. No emergency was declared. The landing at txk airport was without further incident. The aircraft was able to exit the runway and taxi to the ramp under her own power.

Title: C525 CREW HAD THE #1 ENG OIL PRESSURE INDICATE ZERO OIL PRESSURE NECESSITATING AN ARPT DIVERSION.
Narrative: WHILE AT CRUISE AT FL350, THE L ENG'S OIL PRESSURE INDICATING POINTER DROPPED TO ZERO PSI. THIS INDICATION DID NOT TRIGGER EITHER A MASTER WARNING FLASHER, OR A RED INDICATOR LIGHT ON THE CAUTION WARNING PANEL. THIS COMBINATION OF INDICATIONS CAUSED ME TO SUSPECT A FAILED OIL PRESSURE XMITTING DEVICE, RATHER THAN AN ACTUAL LOSS OF OIL PRESSURE. ONCE STARTING THE APPROPRIATE CHKLIST, WE CONTACTED COMPANY MAINT CTL TO CONFER. MAINT CTL ADVISED TO FOLLOW THE CHKLIST. UPON COMPLETION OF CHKLIST, WHICH RESULTED IN SECURING THE L ENG, IT WAS DETERMINED THAT TXK ARPT WAS THE CLOSEST SUITABLE ARPT TO DIVERT TO. ZME WAS ADVISED OF OUR SIT AND REQUEST FOR DEV. NO EMER WAS DECLARED. THE LNDG AT TXK ARPT WAS WITHOUT FURTHER INCIDENT. THE ACFT WAS ABLE TO EXIT THE RWY AND TAXI TO THE RAMP UNDER HER OWN PWR.
