Product Description

Product Description

Endress+Hauser E+H RIA45 Process Indicator with Control 4 - Wire

The Endress+Hauser E+H RIA45 is a 4 - wire process indicator equipped with a control unit, designed as a front - panel - mounted device. It stands out in the industrial measurement landscape for its versatility and high - performance features, making it suitable for a wide range of applications.

Input Capabilities:

Output Features:

Display and User Interface: 

The RIA45 comes with up to two universal sensor inputs. These inputs can accept various types of signals, including voltage (u), current (i), resistance (r), Resistance Temperature Detectors (RTDs), and Thermocouples (TCs). This universal compatibility allows it to interface with a diverse set of sensors, adapting to different measurement requirements. For example, in a chemical plant, it can be connected to RTDs for precise temperature measurements in reaction vessels or to thermocouples in high - temperature furnaces. The ability to handle multiple input types makes the RIA45 a flexible choice for industries where different sensor technologies are used across various processes.

It features 1 x loop power supply, which is crucial for powering two - wire sensors. This integrated power supply simplifies the wiring and installation process, as it eliminates the need for an external power source for compatible sensors. Additionally, the RIA45 may have 2 x analogue outputs (current and voltage), enabling the device to forward process signals to other components in the control system. These analogue outputs can be used to transmit measured values to controllers, recorders, or other monitoring devices. For instance, in a water treatment plant, the analogue output of the RIA45 can send the measured water pressure or flow rate values to a central control station for further processing and analysis.

The RIA45 is equipped with a multicolor backlight LCD. The display offers several visual aids, including a bar graph, unit, and tag indication, along with alarm warnings presented in plain text. The multicolor backlight, which can be white, black, or yellow, enhances visibility in different lighting conditions. The 5 - digit 7 - segment LCD display is easy to read, providing clear numerical values of the measured parameters. The bar graph gives a quick visual representation of the magnitude of the measured value, making it convenient for operators to assess the process status at a glance. The plain - text alarm warnings ensure that any abnormal conditions are clearly communicated, minimizing the risk of misinterpretation.

Company Profile

Company introduction

Main product

KeRui (weifang) Automation Equipment Co., Ltd.specializes in industrial automation instrument development, production and sales, technical services, and supportingequipment supply of specialized companies. The main products are flow meters, level meters, temperature meters,pressure meters, electrical meters, thermal intelligent meters, programmable controllers (PLC)DCS distributed control systems,and eight series of more than 1,000 specifications. Its products and technologies are widely used in electric power, metallurgy, petrochemicals, environmental protection, plastics, food, printing, tobacco,textile, dyeing, and other felds.

Valve Positioner: A valve positioner is a crucial control device that precisely regulates the position of control valves in industrial processes. It receives control signals from a controller and compares them with the actual valve position.

Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel. 

Transmitter: A  transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
