In modern buildings—especially high-rise buildings, shopping centers, hospitals, or cleanrooms—temperature and humidity control play a vital role.

To achieve this, measurement sensors are indispensable. One of the most widely used and reliable devices is the RHP-3S22 temperature and humidity sensor from Dwyer Instruments, USA.

In Vietnam, DLK is the official distributor of Dwyer sensors and measurement equipment, providing optimal solutions for BMS (Building Management System) and HVAC (Heating, Ventilation, Air Conditioning) systems.

This article will analyze the real-world applications of the RHP-3S22 sensor, helping you understand why this product is increasingly favored in high-end projects.

1. Overview of the RHP-3S22 Temperature and Humidity Sensor

The RHP-3S22 is a combined temperature and humidity sensor, specifically designed for HVAC and BMS applications.

Key Features:

• High accuracy: Temperature ±0.5°C, Humidity ±2% RH

• Multiple output options: 4-20 mA, 0-10 VDC, Modbus

• Compact design, easy installation: Suitable for walls, ducts, and technical cabinets

• Long service life: Uses stable digital sensors with minimal drift over time

• Ideal for modern environments: Such as factories, hospitals, offices, and laboratories

2. Applications of RHP-3S22 in BMS Systems

BMS (Building Management System) is an intelligent building management platform that monitors and controls various technical systems like electricity, HVAC, lighting, and security.

The RHP-3S22 enhances BMS performance through:

• Real-time environmental monitoring: Accurately transmits temperature and humidity data to the BMS

• Automated HVAC control: Activates dehumidifiers when humidity exceeds limits or starts air conditioning when temperature rises

• Easy integration: Supports Modbus protocol, compatible with various BMS controllers

• Energy optimization: Accurate data prevents redundant operations, reducing electricity consumption

Thanks to these features, the RHP-3S22 is an ideal choice for office buildings, hotels, and commercial properties implementing smart building systems.

3. Applications of RHP-3S22 in HVAC Systems

HVAC (Heating, Ventilation, and Air Conditioning) systems are found in almost every modern building.

RHP-3S22 plays a key role in HVAC systems by:

• Accurate environmental measurement: Provides reliable data for HVAC controllers

• Balancing temperature and humidity: Ensures a comfortable environment for people and stable conditions for machines

• Application in cleanrooms: Where strict humidity and temperature control is required to meet GMP and ISO standards

• Application in manufacturing plants: Especially in pharmaceuticals, food, and electronics where humidity directly affects product quality

• Energy saving: With precise sensor readings, HVAC systems operate only when necessary

4. Why Choose the RHP-3S22 Sensor for Modern Projects?
