Taylor Instrument Differential Pressure Transmitter 403TB01262A0100

The Taylor Instrument 403TB01262A0100 is a robust differential pressure transmitter designed for industrial applications, including process control in chemical, petrochemical, and manufacturing environments. Manufactured by Taylor Instrument (a division of Combustion Engineering, now part of ABB), this model features a diaphragm-type sensing element with 316 stainless steel wetted parts for corrosion resistance and durability in harsh conditions. It provides a 4-20 mA DC output signal powered by a 24 VDC supply, making it compatible with standard control systems. Key benefits include high accuracy for low-pressure measurements (calibrated to 0-25 inches H2O in this unit, with a max span of 51 inches H2O), explosion-proof certification for hazardous areas (Class I Div 1 Groups C,D; Class II Div 1 Groups E,F,G), and a maximum working pressure of 1000 PSIG, ensuring reliability under high-pressure scenarios. Advantages over similar products include its proven reliability in legacy systems and cost-effectiveness for replacements in older installations. Drawbacks may include limited modern digital interfaces compared to newer models like Rosemount or Yokogawa transmitters, and potential obsolescence for parts. This unit appears unused (open box condition) based on images, with no visible wear, scratches, or damage. It is suitable for measuring differential pressure in flow, level, or filter monitoring applications. For detailed specs, refer to ABB/Taylor legacy datasheets.
