UC800 Differential Pressure Transmitter

The UC800 is a high-performance, industrial-grade differential pressure transmitter designed for precise and reliable measurement of liquid, gas, or steam pressure across a wide range of demanding applications. It converts the differential pressure between its two ports into a standardized analog output signal (e.g., 4-20mA), providing critical data for process control, monitoring, and automation systems. Its robust construction and advanced sensor technology ensure accuracy and stability even in harsh environments.

Key Features

High Accuracy & Stability: Utilizes advanced mems sensor technology with excellent long-term stability and minimal drift.

Robust Construction: Features a durable housing (often stainless steel) and isolation diaphragms suitable for a wide range of industrial media.

Comprehensive Output Options: Standard 4-20mA analog output with HART protocol support for easy configuration, calibration, and diagnostics.

LCD Indicator: Integrated local display with a bar graph and digital readout for pressure and percentage values, facilitating on-site monitoring and troubleshooting.

Wide Rangeability: Offers a broad turndown ratio (e.g., 100:1), allowing one model to cover many application ranges, reducing inventory needs.

Intrinsic Safety and Weatherproof: Typically certified with explosion-proof (Ex d) and intrinsic safety (Ex ia) protections, along with a high IP rating (e.g., IP67) for use in hazardous and outdoor areas.

Typical Applications

The UC800 is versatile and is commonly used in the following scenarios:

  • ​Flow Measurement: Used with orifice plates, venturi tubes, or flow nozzles to calculate flow rate in pipes.
  • Filter & Pump Monitoring: Monitoring the pressure drop across filters (air, water, oil) to indicate clogging status and prevent pump cavitation.
  • Liquid Level Measurement: Measuring the level of liquids in tanks, vessels, and boilers by hydrostatic pressure
  • HVAC Systems: Monitoring air flow and filter status in building management systems.
  • Industrial Processes: Applications in industries such as Oil & Gas, Chemical, Pharmaceutical, Power Generation, Water & Wastewater Treatment, and Food & Beverage.
