Axelson Differential Pressure Sensing Unit

Axelson Differential Pressure Sensing UnitThe Axelson 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 pressures.

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.

When connected 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.

NOTE:

When connecting the inlet to the high port, DO NOT plug the low port.
When connecting the inlet to the low port, DO NOT plug the high port.

Natural Gas for Our Future
Natural Gas an ideal fuel source for many reasons, including safety. Natural Gas is lighter than air. This means that it will not puddle (like gasoline) or sink to the ground like propane, which is heavier than air. Instead, Natural Gas will rise and dissipate in the atmosphere. Natural gas also has a higher ignition temperature. This means that it is much harder to ignite. Also the storage systems used for compressed natural gas are infinitely stronger that the gasoline tanks found on cars and trucks today.
