Gauge Protector and Piston Separator

Pressure Sensors and Diaphragm Protectors

Gauge Protector


Crown’s gauge protectors (CD106) (the smaller protector seen in the image on the right) is an integral part of any pressure system. Designed to protect the working parts of a pressure gauge from harsh drilling fluids, Crown gauge protectors are durable and dependable in the harshest drilling instances. Two kinds of rubber cups are available for our gauge savers: a CD200 and CD200-1 Viton cup, rated for H2S service. Easy to maintain in the field, these pressure sensors will provide you with years of dependable service.


1:1 Piston Separator


Crown’s 1:1 Piston Separator pressure sensor (CD136) offers the same protection as the CD106, but have a 1:1 piston that transmit pressure to the gauge.  Because this pressure sensor is built with the sturdiest material, it will provide years of service, even in the toughest conditions.

All Crown Hydraulic Pressure Sensors are built to meet or exceed API specifcations.
