Description
Yokogawa UT52A-010-11-00 Pressure Transmitter
Product Overview
The Yokogawa UT52A-010-11-00 is a digital, two-wire, flange-mounted pressure transmitter from Yokogawa’s (UniTrans™) family. This specific model is designed for low-pressure, low-differential pressure, or liquid level measurement applications, particularly where a compact, flange-mounted installation is required. The «UT52A» indicates the series and sensor type (low differential pressure), and the suffix «-010-11-00» precisely defines its measurement range, output signal, process connection, and other options.
This transmitter is a «smart» device that converts the applied differential pressure into a standardized 4-20 mA DC analog signal (with HART protocol superimposed) for transmission to a DCS, PLC, or indicator. It features a single, compact housing that integrates the sensor, amplifier, and terminal compartment. Its robust construction and high accuracy make it suitable for demanding process environments in various industries.
Technical Specifications (Decoded from Model Code)
Summarized Core Specifications:

Electrical Connection: 1/2” NPT conduit entry with a terminal block.
Main Features and Advantages
-
High Accuracy & Stability: Utilizes a high-performance silicon resonant sensor, offering excellent long-term stability and repeatability, ideal for precise low-pressure or level measurement.
-
Compact, Integral Design: The sensor and electronics are housed in a single, robust unit, simplifying installation and reducing potential leak points compared to remote seal systems.
-
Digital Communication (HART): Enables remote configuration, ranging, calibration, and diagnostics using a HART communicator or asset management software (e.g., Yokogawa PRM), reducing maintenance time and costs.
-
Robust Construction: Designed for harsh industrial environments with high resistance to vibration, corrosion, and wide temperature variations.
-
Easy Maintenance: Local zero and span adjustments can be made via the magnetic switch on the housing (with a magnet tool) or via HART.
Application Fields
The UT52A is ideal for applications requiring precise measurement of very low differential pressures or liquid levels:
-
Clean Gas/Liquid Flow: With an orifice plate or Venturi tube for low flow rate measurement.
-
Filter Monitoring: Measuring pressure drop across air or liquid filters to indicate clogging.
-
Liquid Level in Tanks: Measuring the level of non-crystallizing, non-viscous liquids in vented or pressurized tanks (using the differential pressure method).
-
Furnace/Boiler Draft Pressure: Monitoring very low positive or negative pressures.
-
Cleanrooms & HVAC: Monitoring room pressurization.
Related Products & System Integration
-
Impulse Piping/Tubing: To connect the process flanges to the measurement points.
-
HART Communicator/Configurator: Yokogawa YHC5150 or other HART-compatible handheld device for configuration.
-
Asset Management Software: Yokogawa Plant Resource Manager (PRM).
-
Isolating/Diaphragm Seals: For applications with viscous, slurry, or high-temperature media to protect the transmitter diaphragm (not typically used with this flange-mount style).
-
Mounting Bracket: For additional support if not directly mounted to the process.
-
Power Supply/Isolator: A 24V DC loop power supply with signal isolation.
