ProSight Wall Type Room Temperature and Humidity Transmitter RS482 4-20ma
ProSight Wall Type Room Temperature and Humidity Transmitter RS482 4-20ma is a wall-mounted environmental transmitter for measuring indoor air temperature and relative humidity. It is primarily used in building automation, HVAC systems, hotels, libraries, clean rooms, warehouses, medical facilities, supermarkets, and other indoor environments. Key features include high accuracy and stability, selectable temperature ranges, fast response, optional LCD indication, and 4-20mA, 0-5VDC, 0-10VDC, or RS485 Modbus RTU outputs.
The ProSight Wall Type Room Temperature and Humidity Transmitter RS482 4-20ma is a wall-type room temperature and humidity transmitter designed to continuously monitor indoor environmental conditions. It combines temperature and relative humidity measurement in one compact wall-mounted device, making it suitable for applications where accurate environmental data is needed for monitoring, automation, and climate control.
The transmitter uses an advanced sensor module and high-performance processing technology to measure the surrounding air. It is designed for applications including building automation, hotels, libraries, rooms, clean rooms, dust-free workshops, medical facilities, warehouses, supermarkets, and other indoor environments.
The ProSight Wall Type Room Temperature and Humidity Transmitter RS482 4-20ma can be ordered with or without an indicator. The indicator version allows users to view measured conditions locally, while non-display versions are suitable when readings are monitored remotely through a control or building management system.
How Does it Work?
The ProSight Wall Type Room Temperature and Humidity Transmitter RS482 4-20ma continuously senses the surrounding air temperature and relative humidity. The internal electronics process the sensor signals and convert the measurements into electrical output signals that can be transmitted to a connected monitoring or control system.
Depending on the selected configuration, the transmitter provides:
- 4-20mA output for industrial control and monitoring systems.
- 0-5VDC output for compatible controllers and data acquisition systems.
- 0-10VDC output for building automation and industrial control equipment.
- RS485 output for digital communication.
- Modbus RTU protocol for integration with compatible PLCs, BMS, SCADA, and automation systems.
The temperature measurement range can be selected from -20 to 80°C, 0 to 50°C, or -40 to 60°C, while relative humidity measurement covers 0-99.9% RH. The temperature range can be set using a DIN switch, allowing the device to be adapted to different monitoring requirements.
The transmitter provides a fast response, with a specified temperature response time of approximately 3 seconds and humidity response time of approximately 5 seconds under the stated test conditions. This allows the system to respond quickly to changes in indoor environmental conditions.
