Axelson Differential Pressure Sensing Unit
Differential Pressure Sensing Unit is designed to attach to a standard ESP
Body Subassembly to form a differential pressure sensor.
The sensor may be used to detect a predetermined difference between two
The Differential Pressure Sensing Unit is a
three-way block and bleed control valve which is controlled by a differential
pressure sending piston assembly. It may be connected as a high or a low
sensor. The set point of the sensor is adjustable by rotating the spring
cap, thus varying the spring force which opposes the force of the differential
pressure acting across the diaphragm.
When connected as
a HIGH sensor, control pressure is allowed to flow through the control to
the outlet as long as the differential pressure sensed remains below the set
point of the sensor. When the set point is exceeded, the inlet port is blocked
and the outlet port is open to exhaust.
as a LOW sensor, control pressure is allowed to flow through the control
to the outlet as long as the differential pressure sensed remains above the set
point of the sensor. When pressure declines below the set point, the inlet port
is blocked and the outlet port is open to exhaust.
