Downhole pressure gauge, PPS 25XM - Critical Well Memory Gauge

PPS25XM - Critical Well Memory Gauge

The PPS25-XM is designed for critical well conditions by welding the sapphire sensor with the housing, so there is no potential leaking pass between sensor and the housing. Both metal to metal and elastomer seals are used to secure the sealing between battery housing and electronic section. Six pin with locking mechanism connector is used to provide dual power channels and prevent battery disconnection during operations.
