Application

Multiple probe types are available and suitable for different sites, commonly used in harsh environmental pipeline applications: temperature and humidity measurement of smoke exhaust pipes, warm ventilation pipes/HAV HVAC/air conditioning cold and hot system air ducts, temperature and humidity detection of outdoor air ducts (H2N) or harsh environments (H3N), split plug-in locations (H4N), and other pipeline scenarios.

The HG803 air duct series transmitter is paired with a sensitive waterproof and fine dust resistant high-temperature probe, with a temperature range of -40~80 ° C. Adopting standard industrial interface RS485 digital signal output, it can be connected to on-site digital display meters, PLCs, frequency converters, industrial control hosts, and other equipment.

The pipeline type temperature and humidity transmitter is very suitable for measuring temperature and humidity in various places suitable for pipeline installation, such as air ducts, flue gas ducts, sealed containers, central air conditioning inlet and outlet. The transmitter comes with a tubular probe or a flange. It can be directly installed on the outer wall of the same pipeline. The transmitter can output the temperature and humidity values inside the pipeline in the form of voltage signals, current signals, and RS485 signals.

Q: What is the common use of a Temperature and Humidity Sensor?
A: Temperature and Humidity sensors are among the most commonly used environmental sensors. It is widely use to provide the actual humidity condition within air at any given point or in any given place. Such devices are commonly used in situations in which air conditions may be extreme or where air conditions need to be controlled due to varying reasons.

 

Q: Why is Temperature and Humidity Sensor important in some of the industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.

 

Q: How do I choose a suitable Temperature and Humidity Sensor?
A: There are a some important specifications you might need to consider when you choosing this product. This includes:

* Accuracy
* Long-term stability

* Ability to recover from condensation

* Resistance to physical and chemical contaminants

*Interchangeability

* Repeatability
