Honeywell 51202304-100 Differential Pressure Transmitter

Description

Honeywell 51202304-100 Differential Pressure Transmitter

Product Dimensions：

Honeywell offers industry-leading Differential Pressure (DP) Transmitters, primarily under the SmartLine® ST800 and ST700 series. These high-performance instruments are designed to measure the difference between two pressures and convert it into an electrical signal for process control and monitoring.

Product Detailed Description

Honeywell SmartLine DP Transmitters utilize advanced piezoresistive sensor technology. By combining differential pressure sensing with on-board static pressure and temperature compensation, these devices deliver exceptional accuracy and stability even under harsh operating conditions. They can be configured with various process connections, including traditional flanges, remote seals, or manifolds, to measure flow, liquid level, or filter degradation.

Typical Technical Parameters

Specifications below represent the premium SmartLine ST800 series.

Product Advantages

• Modular Design: Electronics modules, alphanumeric displays, and terminal blocks can be replaced or upgraded in the field without affecting the transmitter’s calibration or breaking the process seal.
• Dual-Surface Diagnostics: Advanced diagnostic capabilities monitor both the sensor health and the process loop conditions, helping operators detect issues like plugged impulse lines.
• Integrate Architecture: Seamless integration with Honeywell Experion® PKS provides transmitter messaging, maintenance mode indications, and tamper alerts directly to the control room.
• Intuitive Display: Available with an advanced graphic LCD that supports multi-language displays, trend charts, and clear diagnostic messaging.

Important Considerations & Precautions

• Impulse Line Routing: For liquid or steam applications, mount the transmitter below the process taps and slope the impulse lines downward to prevent gas bubbles from trapping. For gas applications, mount the transmitter above the taps to allow condensate to drain back into the process.
• Static Pressure Over-loading: When commissioning the unit, open the stabilizing (equalizing) valve on the manifold first before opening the high and low-pressure block valves to prevent accidental over-pressurization on a single side of the sensor capsule.
• Material Selection: Ensure that the selected wetted materials (diaphragm and fill fluid) are compatible with the process medium to avoid hydrogen permeation or chemical corrosion.
• Seal Integrity: Regularly check the O-rings and process flange bolts for leaks, especially in high-temperature or thermal-cycling processes.

Product Applications

• Flow Measurement: Paired with primary flow elements like orifice plates, Venturi tubes, or Pitot tubes to calculate fluid, gas, or steam flow rates.
• Liquid Level Measurement: Measuring the hydrostatic head in pressurized or open vessels to determine tank level, density, or interface layers.
• Filter Monitoring: Measuring the pressure drop across industrial filters, strainers, or heat exchangers to trigger backwash sequences or maintenance alerts.
• Draft and Furnaces: Monitoring low-pressure draft conditions inside industrial boilers, kilns, and exhaust stacks.
