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

PPS25XM - Critical Well Memory Gauge

By welding the sapphire sensor with the housing, the PPS25-XM is designed for critical well conditions, because this reduces the potential leaking that can pass between the sensor and the housing. Both metal to metal and elastomer seals are used to secure the seal between the battery housing and the electronics. A six pin locking mechanism connector is used to provide dual power channels and prevent battery disconnection during operations.
