4 Steps You Need to Know How to Select a Suitable Temperature and Humidity Transmitter?

 

Temperature and humidity transmitters are only one of the temperature and humidity sensors products, just the air temperature and humidity through a certain detection device, measured temperature and humidity, according to a certain law into electrical signals or other required forms of information output, to meet user needs. So, what should be attentive when choosing the temperature and humidity sensor products?  

1. Selecting the Measurement Range: 

Accuracy is an important indicator in the selection of temperature and humidity sensor products. Determine the measurement range of the temperature and humidity sensor according to your application. Generally speaking, meteorological or scientific research temperature and humidity departments have a wide range of requirements for temperature and humidity ranges. The default measurement range of HENGKO temperature and humidity sensor product is -40…125℃,0…100%RH. 

2. Selecting the Measurement Accuracy: 

Measurement accuracy is also an important indicator of the sensor, and you can choose the appropriate accuracy according to your own field and needs. For example, hospitals, refrigerated transportation and other industries have relatively high temperature and humidity accuracy, while factories and manufacturing industries may not have such high requirements for measurement accuracy. The default measurement accuracy is ±0.2℃, ±2.0%RH. Another accuracy is also available, please contact our sales for details.

3. Consider the Time and Temperature Drift: 

In practical use, due to the influence of some occasions, such as dust, oil and harmful gas. Once used for a long time, the  the temperature and humidity sensor will produce certain aging, precision decline, the annual drift of the sensor will generally be about plus or minus two percent, or even higher. Therefore, temperature and humidity sensor manufacturers in the sale of the product, generally remind, use one to two years need to mark the product again.

4. Selecting the Suitable Transmitter Type:

Determine the appearance of the device according to the specific environment in which the device is used. For example, if you need a screen display, you can choose our HT-802C temperature and humidity transmitter with a larger LCD display.

HENGKO HT802C temperature and humidity transmitteradopts high-precision RHT series sensors and a large-screen liquid crystal display. It has the characteristics of high measurement accuracy and good stability, which ensures the excellent measurement performance of the product. Equipped with a dedicated 485 circuit, the communication is stable. Complete specifications, easy installation

HT-802W/HT-802X wall-mounted temperature and humidity transmitter standard industrial 4~20mA/0~10V/0~5V analog signal outputs, and can be connected to a digital display meter, PLC, frequency converter, industrial control host and other equipment. It is mostly used in the situation of bad outdoor and on-site environments. The applications are usually communication rooms, warehouse buildings and automatic control and other places that need temperature monitoring.
