UC800 Differential Pressure TransmitterThe 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 FeaturesHigh 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 ApplicationsThe 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.
