VISÃO GERAL

Description

Honeywell’s Model 427 Wing Union/Hammer Union Pressure
Sensors are rugged devices designed for use with Weco® 1502
(2 in.) fittings for both offshore and land-based oil and gas
applications, such as well stimulation and circulation system
monitoring.
Model 427’s newly designed aperture has a wide and shallow
sensing port to handle more viscous drilling mud blends and enable
a seamless flow of media through the sensing area. Available
with an accuracy level of ±0.2 % BFSL (Best Fit Straight
Line), this sensor provides consistent and accurate pressure
measurements in challenging drilling applications such as extended
reach drilling or heavy crude oil drilling.
Model 427 is constructed as an all-welded, stainless steel
assembly with the sensor diaphragm and wing union fitting machined
as one part. This helps provide hermetic integrity, which
lessens the chance of media leakage vs. multi-piece parts, and
increases reliability. The isolated, pressure sensing diaphragm
minimizes zero-shift during hammer up and eliminates long term,
signal drift in the field. The Weco® 1502 Wing Union compatible
fittings are machined of Inconel® X-750, which provides additional
durability with highly abrasive and corrosive media, while
the Honeywell proprietary stainless steel electrical connection
delivers enhanced secondary pressure containment.
Each sensor undergoes special assembly processes to test
shock and vibration for reliable performance in the field.
