Honeywell 434 435 437 Series Wing Union Hammer Union Pressure Transducer with Weco® 1502/2002/2202 Compatibility 4-20mA Output and 9-28Vdc Supply Voltage

DESCRIPTION
Models 434/435/437 Wing Union/ Hammer Union Pressure Sensors are designed for demanding oil and gas applications as well as stimulation and circulation systems. They are
constructed as an all-welded, stainless steel assembly with the sensor diaphragm and wing union fitting machined as one part, which provides hermetic integrity and minimizes media leakage versus multi-piece parts. The isolated pressure sensing diaphragm minimizes zero-shift during hammer up and eliminates long-term signal drift in the field. The Weco® 1502, 2002, and 2202 Wing Union-compatible fittings are machined of Inconel® X-750, or optional NACE-compliant Inconel® 718, allowing for use with abrasive
and corrosive media. The Honeywell proprietary stainless steel electrical connection provides enhanced secondary pressure containment. Special assembly processes provide enhanced shock and vibration for reliable performance in the field.

DIFFERENTIATION
•High or standard accuracy allow ability to obtain tighter system requirements and lower error bands than comparable competitive models
•Shunt calibration option enhances configurability and flexibility; 1-wire shunt calibration is achievable with a single barrier application, helping to minimize installation costs
•IEC Ex approval allows for use in hazardous areas, in Asia-Pacific and EMEA, and by the U.S. Coast Guard
•Protective cage option
•Welded construction

VALUE TO CUSTOMERS
•Durable: Weco® Wing Union- compatible fittings are machined of Inconel® X-750, or optional NACE- compliant Inconel® 718, allowing for use with abrasive and corrosive media. Protective cage option provides electrical connection protection.
•Reliable: All-welded, stainless steel assembly, shock/vibration ratings, and isolated pressure sensing diaphragm increase reliability.
•Accurate: High accuracy option provides confidence in the actual measured pressure value,
particularly for smaller changes in pressure, allowing drilling operation adjustments as needed.
•Availability and service: Global manufacturing and support allow Honeywell to quickly provide customized products, helping customers meet project timelines
APPLICATIONS
•Acidizing, choke manifold, fracturing and cementing, measurement
while drilling (MWD), mud pumps/ mud logging, new well development and extraction, oil and gas drilling,
service and cement trucks, standpipe, stimulation, well head measurement

±0.2 %FSS BFSL
(Models 434/435/437)
•Standard aperture (Models 434/435) and wide aperture (Model 437) pressure ports support media blends with high viscosities
•Inconel® X-750 or optional NACE- compliant Inconel® 718 wetted parts
•Multiple electrical connectors supported
•Pressure connections: WECO® 1502, 2002, 2202
•High accuracy 1-wire or 2-wire shunt calibration option allows ability
to validate the offset signal in the field, ensuring the sensor is actively plugged into the system
•Protective cage option
•RFI/EMI protected
•Intrinsically safe: CFMUS/ATEX/ IEC Ex certification
•CE approved

1Accuracies stated are with respect to best fit straight line (BFSL) for all errors including linearity, hysteresis, and non-repeatability through zero.

2 Working pressure and approval limited to 15000 psi [1000 bar]. Amplifier enhancement options 3H and 3HJ will allow overpressure reading to 20000 psi [1350 bar] (for Models 435 and 437).

3 Optional high accuracy
