Honeywell PA7OVAGHE High performance instrument

Honeywell pressure transmitters are robust, high-performance instruments designed to accurately measure gas, liquid, or vapor pressure in various industrial, commercial, and building management applications. They convert the measured pressure into a standardized electrical signal (e.g., 4-20 mA, 0-10V, Modbus) for monitoring, control, and data acquisition by control systems like PLCs, DCS, or building management systems (BMS).

Product Detailed Description

• Function: The primary function is to measure pressure accurately and reliably and convert this analog pressure value into a proportional electrical signal. This signal can then be used by control systems to regulate processes, monitor conditions, or activate alarms.

• Operating Principle: Pressure transmitters typically use a sensing element (e.g., piezoresistive, capacitive, thin-film strain gauge) that deforms with applied pressure. This deformation is then converted into an electrical signal, which is conditioned and amplified by internal electronics before being outputted.

• Key Features (Common to Honeywell Pressure Transmitters):

• High Accuracy: Designed for precise measurement, often with accuracies of ±0.25% to ±0.5% of span.

• Robust Construction: Built with durable materials (e.g., stainless steel housing, various wetted parts) to withstand harsh industrial environments, including vibration, shock, and temperature extremes.

• Wide Pressure Ranges: Available in a multitude of ranges from very low (e.g., 0-1 PSI) to very high (e.g., 0-10,000 PSI or more) for gauge, absolute, or differential pressure.

• Variety of Outputs: Common analog outputs include 4-20 mA (two-wire or three-wire), 0-5V DC, 0-10V DC. Digital outputs like Modbus RTU might also be available on some advanced models.

• Process Connections: Offered with a wide range of standard industrial process connections (e.g., NPT, G, R, flanged) to facilitate easy installation.

• Electrical Connections: Various electrical connections are available, including integrated cables, DIN connectors, M12 connectors, or conduit entries.

• Temperature Compensation: Internal temperature compensation ensures stable readings across varying ambient temperatures.

• Certifications: Many models carry approvals for hazardous locations (e.g., ATEX, IECEx, FM, CSA) and other industry-specific certifications (e.g., CE, RoHS).

• Long-Term Stability: Engineered for minimal drift over time, reducing the need for frequent recalibration.

Product Parameters (Typical, not specific to PA7OVAGHE)

• Pressure Type: Gauge, Absolute, or Differential Pressure (the "PA" in your model could suggest "Pressure Absolute").

• Pressure Range: Varies widely (e.g., 0 to 100 PSI, 0 to 10 Bar, 0 to 100 kPa). You would need to consult the specific datasheet for PA7OVAGHE.

• Output Signal:

• Analog: 4-20 mA (most common for industrial), 0-5V DC, 0-10V DC.

• Digital: (Less common for basic models, but possible for advanced ones, e.g., Modbus RTU).

• Supply Voltage: Typically 8-30 VDC (for 4-20mA), 12-30 VDC (for voltage outputs).

• Media Temperature: Varies, e.g., -20°C to +125°C.

• Ambient Temperature: Varies, e.g., -40°C to +85°C.

• Wetted Materials: Stainless Steel (316L, 17-4 PH), Hastelloy, Ceramic, etc. (chosen based on media compatibility).

• Housing Material: Stainless steel, plastic, or aluminum.

• Process Connection: Various thread sizes (e.g., 1/4" NPT, 1/2" NPT, G1/4, G1/2), or flanged connections.

• Electrical Connection: Cable gland, M12 connector, DIN 43650 connector.

• Enclosure Rating: Typically IP65, IP67, or IP68.

• Response Time: Usually very fast, in milliseconds.

• Certifications: CE, RoHS, UL, ATEX, IECEx (if for hazardous areas).

Product Advantages

• High Performance: Delivers accurate, repeatable, and reliable pressure measurements crucial for precise process control.

• Durability and Robustness: Built to operate reliably in challenging industrial environments, resisting shock, vibration, and temperature fluctuations.

• Wide Application Versatility: A broad range of pressure types, ranges, outputs, and connections makes them suitable for diverse industries and applications.

• Energy Efficiency: Low power consumption for efficient operation.

• Ease of Integration: Standard analog outputs (4-20 mA, etc.) and common industrial connections facilitate seamless integration into existing control systems.

• Reduced Maintenance: High long-term stability minimizes the need for frequent calibration, reducing operational costs.

• Global Support: As a leading global brand, Honeywell offers extensive technical support and service.

Precautions

• Correct Selection: Crucial to select the correct pressure range, output type, process connection, and wetted materials based on the specific application's media, pressure limits, and environmental conditions.

• Proper Installation: Install the transmitter according to Honeywell's specific instructions. Ensure the process connection is leak-free and the transmitter is securely mounted to avoid vibration damage. Avoid over-tightening.

• Media Compatibility: Verify that the wetted parts of the transmitter are chemically compatible with the media whose pressure is being measured to prevent corrosion and premature failure.

• Overpressure Protection: Do not expose the transmitter to pressures exceeding its specified maximum overpressure limit, as this can cause permanent damage.

• Electrical Connections: Follow wiring diagrams precisely. Ensure correct power supply voltage and polarity. Proper grounding is essential to prevent electrical noise and ensure safety.

• Environmental Conditions: Operate within the specified ambient temperature and humidity ranges. Protect from direct exposure to corrosive chemicals or excessive dust/moisture if the IP rating is not sufficient.

• Calibration: While factory calibrated, periodic recalibration may be necessary to maintain specified accuracy, especially in critical applications or after harsh operating conditions.

• Hazardous Area Compliance: If used in hazardous locations, ensure the specific model has the required certifications and that installation complies strictly with local electrical codes and the certification requirements (e.g., intrinsic safety barriers).
