What is a Temperature Humidity Transmitter? How to Choose One?
A temperature humidity transmitter is an essential industrial device that helps measure and control the environment accurately. If you are looking for precise and durable temperature and humidity transmitters, whether for duct mounting or outdoor use, this article provides a comprehensive guide to help you make confident purchasing decisions with comparisons of specifications and prices across various models. For immediate consultation, visit SCMA Services
What is a Temperature Humidity Transmitter? And Why Is It Important?
A temperature humidity transmitter, or humidity and temperature signal transmitter, is an electronic device that measures the air's temperature and relative humidity values and converts them into standard electrical signals (such as 4-20mA or 0-10V) to send data to automatic control systems (PLC), SCADA systems, or data loggers.
Basic Working Principle
The operation of this device starts with temperature sensors and humidity sensors inside or separate from the unit. They detect physical changes in the air, then internal circuits process and convert these values into stable electrical signals for long-distance data transmission without distortion.

The Importance of Temperature and Humidity Control in Industries and Buildings
Controlling temperature and humidity is crucial for maintaining product quality, such as in the pharmaceutical, food, and electronics industries. It also helps save energy in large building HVAC systems. Investing in high-quality temperature and humidity sensors is a worthwhile long-term investment.
Types of Temperature Humidity Transmitters You Should Know
There are several types designed for different installation environments on the market.
Duct Mount Type
Also known as Duct Mount Transmitter, it is designed with a probe extending into ducts to measure air temperature and humidity in HVAC systems. Suitable for building HVAC control.
Wall Mount / Outdoor Type
For wall mounting or outdoor use, these models have robust structures resistant to sun and rain (high IP rating) suitable for measuring external weather conditions or in greenhouses.
Remote Probe Type
Ideal for hard-to-reach areas with high temperatures, the unit is installed separately and connected to the probe via a signal cable. This makes it easy to read values and extends electronic circuit lifespan. Learn more about sensor types at Temperature – Humidity Sensor
Specialized Area Type (e.g., Clean Rooms)
Designed with smooth surfaces to reduce dust accumulation and withstand cleaning chemicals. Suitable for hospitals, pharmaceutical factories, or labs.
5 Key Factors in Choosing a Temperature Humidity Transmitter
To get the most suitable transmitter, consider these important factors:
1. Application & Environment
Know where you will install it first. If in a cold room, choose models that withstand low temperatures; if in chemical plants, select materials resistant to corrosion.
2. Desired Output Signal (4-20mA, 0-10V, RS485)
Choose the output signal that matches your existing control system, such as PLC systems commonly using 4-20mA due to its noise resistance. Smart Farm applications may prefer RS485 Modbus.
3. Measurement Range & Accuracy
Select a measurement range that covers actual usage and acceptable accuracy levels, such as ±3%RH for general work or ±1-2%RH for high precision tasks. Learn more about measuring instruments at Temperature Humidity Meter
4. Material & IP Rating
IP ratings are crucial for outdoor or high humidity environments, such as IP65 or IP67.
5. Calibration & Maintenance
Choose models with easily replaceable probes or easy calibration options to ensure accurate readings always.

Frequently Asked Questions
How Often Do You Need to Calibrate?
Generally, calibration is recommended at least once a year or more frequently in harsh environments for data accuracy.
What Are the Differences Between Output Signals?
4-20mA transmits signals over longer distances and resists noise better than 0-10V, while RS485 is a digital system that can transmit multiple values and connect several units on one line.
How Long Do Sensors Last?
It depends on the environment. With corrosion or dust, lifespan may shorten; typically, high-quality sensors last around 1-3 years.
