Core Product Series & Key Advantages

1. Pressure Transmitters

• Flagship Models:

  • 3051C/S Series: Industry benchmark for differential pressure (DP) measurement. Features Saturn™ sensor technology with 0.04% accuracy, HART/Foundation Fieldbus protocols, and SIL 2/3 safety certification. Coplanar™ design integrates manifolds, seals, and primary elements into a single unit, reducing leak points by 50%.

  • 2088 Series: Compact, low-power transmitters with 0.1% accuracy and 50:1 turndown. Ideal for direct mounting in space-constrained applications.

  • 4500/2090F Series: Sanitary-grade transmitters compliant with FDA, 3A, and EHEDG standards for food, beverage, and biopharma.

• Advantages:

  • 10-year operational life with vibration/overpressure resistance.

  • Pressure-Lock™ valve technology (R305/R306) simplifies high-pressure maintenance and eliminates fugitive emissions.

2. Temperature Sensors

• 214C RTD Series: Pt-100 sensors for -196°C to 600°C ranges. Offers A/B-class accuracy, Callendar-Van Dusen constants for transmitter-sensor matching, and vibration-resistant designs (3g tested).

• WR/WZ Series: Thermocouples and RTDs with modular connections for hazardous areas.

• Advantages:

  • Fast response (10.8s in water flow per IEC 60751) and long-term stability.

3. Flow Measurement

• Electromagnetic Flow Meters (e.g., 8721):

  • FDA-approved materials, EHEDG/3A certification.

  • 0.25% accuracy at 13:1 rangeability; handles slurries and corrosive fluids (e.g., H₂SO₄, NaOH) via customizable electrodes (Hastelloy B/C, titanium).

• Vortex Flow Meters (e.g., 8800):

  • Redundant SIL 3-certified design (quad-sensor option for 2oo3 voting).

  • 0.65% liquid / 1% gas accuracy; no-gasket body eliminates leaks.

• Compact Orifice Plates (405 Series:

  • Reduces installation cost by 50% vs. traditional DP meters. Requires only 2x pipe diameter upstream for ±0.5% accuracy.

4. Level & Analytical Instruments

• Radar Level Transmitters:

  • Guided-wave radar for liquids/solids; immune to temperature, dust, or density changes.

• CEMS (Continuous Emissions Monitoring):

  • Handles high-dust, corrosive flue gases (e.g., power plants, incinerators) with extraction/dilution sampling.

• Conductivity Sensors (e.g., 200/228 Series):

  • Ring-design electrodes resist fouling; Pt-black coating minimizes polarization. Used in ultrapure water (pharma) and wastewater.

5. Valve Manifolds & Accessories

• R305/R306 Valve Manifolds:

  • Pressure-Lock™ seals isolate stem threads from process fluids, preventing corrosion. Modular packing enables maintenance without shutdown.
