6-Things you Need to Know Before Wholesale Temperature and Humidity Transmitter ?


How to choose a Temperature and Humidity Transmitter ?


It may be one of the most complicated questions for some newbies or end users in the Industry Humidity Sensor. So maybe you

can read as follow checklist when order one Temperature and Humidity Transmitter :

1.)  To Confirm What is the Sensor Chip of the Transmitter because the CPU chip determines the

       precision and accuracy of your temperature and humidity sensor data. 


2.) The sensor probe is suited for your sensor detection environment, some Temperature And Humidity Transmitter is with 

low-quality sensor protector, and Some transmitters have a sensing head of just ordinary polyester material. Still, some

sensing heads cannot meet the requirements of filtering impurities in the air, leading to inaccurate detection data.


3.) The temperature measurement range should be confirmed -40....+60°. If you need a high-temperature or corrosive

environment, choose a high-temperature, corrosion-resistant sensor head, and humidity transmitter. Such as can load

-70 .... +180° sensor probe. Special need to confirm the sensor cover.


4.) For harshest environments, Maybe you should choose the solution of remote detection of temperature and humidity.


5.)  Also, for installation, you should confirm the best way to install your humidity transmitters. Normally, we can supply

Wall mounting, hanging, narrow space and pipeline installation, high-temperature and high-pressure installation,

high-pressure vacuum environment installation, pressure pipelines, etc., the requirements of different environments on

the installation will also vary.


6.) Other details of data about the transmitter, such as detection accuracy, detectable temperature, humidity, dew point range,

and whether the anti-reverse connection function, so please confirm details with our salesman before placing to order.

 Faq of Temperature and Humidity Transmitter


FAQ About Industry Temperature and Humidity Transmitter


 1. What is Temperature and Humidity Transmitter 

Temperature and humidity transmitters are temperature and humidity integrated probes as temperature measurement


The temperature and humidity signals are collected after voltage stabilization and filtering, operational

amplification, non-linear correction, V/I conversion, constant current and reverse protection circuit processing, converted

into a linear relationship with the temperature and humidity current signal or voltage analog signal output, 4-20mA, 0-5V

or 0-10 V, can also be directed through the It can also be output directly through the master control chip for 485 or 232


Widely used in communication rooms, warehouses, food processing, pharmaceutical products, medical experiments,

agricultural production and self-control, and other places that need temperature and humidity monitoring.


2. How does Industry Humidity Sensor Work ? 

    Firstly, Industry Humidity Sensor , also known as humidity Transmitter,  main to used to monitor the humidity

of the environment, now for most transmitter with temperature test integrated, but how does the industry

humidity sensor work ?    

Typically, humidity sensors contain a humidity sensing element and a thermistor, which is used to measure temperature. There are three main types of humidity sensors, each of which monitors small atmospheric changes to calculate humidity. These types include:

1. Capacitive humidity sensors
Capacitive humidity sensors are linear and measure relative humidity from 0% humidity to 100% humidity. They do this by placing a small metal oxide strip between two electrodes. As the level of humidity changes, the oxide's electrical capacity changes along with it.

2. Resistive humidity sensors
Resistive humidity sensors measure humidity by using ionized salts between two electrodes. The ions in the salts measure the electrical impedance of atoms. As humidity levels change, so does the resistance of the electrodes.

3. Thermal sensor.
A thermal sensor utilizes a dual sensor system to measure humidity. One thermal sensor is housed in a layer of dry nitrogen; the other freely measures ambient air. The resulting difference between the two measurements represents the air's moisture level.


A humidity sensor (or hygrometer) senses, measures and reports both moisture and air temperature.

Humidity sensors work by detecting changes that alter electrical properties in the air.

3. How to Test Dehumidifier Humidity Sensor ? 

Electronic sensors measure humidity by measuring the capacitance or resistance of air samples.


 Questions about manufacture and place a order:

Q1. Are you manufacturer or trading company?

--We are direct manufacturer specializing in porous sintered metal filters.

Q2. What’s the delivery time ?
--Normal model 7-10 work days because we have ability to do the stock. For big order, it takes about 10-15 work days.

Q3. What is your MOQ?

-- Usually, it is 100PCS, but if we have other orders together, can help you with small QTY also.

Q4. What payment ways available?

-- TT, Western Union, Paypal , Trade assurance, etc.

Q5. If sample first possible?

-- Sure, usually we have certain QTY of free samples, if not, we'll charge accordingly.

Q6. We have design, can you produce as our design?

--Yes, welcome to send your design, so we can supply fast solution and process list.

Q7. Which market do you already sell?
--We already ship to Europe, Middle East, Asia, South America , Africa, North America etc.


For a capacitive hygrometer, the air flows in between two metal plates. The change in air moisture is

directly proportional to the change in capacitance between the plates. In a resistive hygrometer, a ceramic

or conductive polymer absorbs moisture, affecting its resistivity.


It is connected to a circuit where the moisture affects the material's resistance. The relative humidity is

then determined based on the change in current.


Hygrometers are often outfitted with a temperature sensor and a barometer which combine the temperature

and pressure data and the capacitance/resistance change to measure the humidity.
