The Yokogawa UT152-RN is not a standalone transmitter or controller. It is a remote display unit (also called a remote indicator or auxiliary display) designed to be mounted on a panel or in a location separate from the main instrument.
Key Features and Specifications
Primary Function: Remote digital display for process variables (e.g., flow rate, total flow, temperature).
Input Signal: Digital communication signal from a compatible Yokogawa transmitter (e.g., via a dedicated RS-485 or other proprietary communication link). *It does not accept a direct 4-20 mA analog signal.*
Display: 8-digit LED display (typical for this series) for high visibility. It often can display engineering units (e.g., m³/h, GPM, °C).
Mounting: Panel Mount (Cutout mounting). The -RN model is designed to be installed by cutting a hole in a panel or console door.
Power Supply: Typically powered by the main transmitter via the communication cable or requires a separate low-voltage DC power supply (e.g., 24 V DC).
Key Feature: Provides a repeated display of the value shown on the main transmitter's screen. It allows operators to read the value without needing to access the field-mounted transmitter.
Compatibility: Designed to work with specific Yokogawa transmitters. The exact compatibility must be checked with Yokogawa's documentation (e.g., it is commonly paired with UT550, UT750, and other advanced UT series flowmeters).
Typical Applications
This unit is used in scenarios where remote monitoring is required:
Control Rooms: Displaying flow data from a field-mounted ultrasonic flowmeter on a control panel.
Operator Stations: Providing a local readout in a convenient location for operators to check without going into the field.
Pump Stations: Monitoring flow rates from a central location within the station.
Water and Wastewater Plants: Displaying flow data from various points around the plant in a central monitoring room.
