High temp. temperature humidity sensor transmitter is developed on industrial class standard and has its own unique designing ideal to meet more rugged application. It design is different from common type temperature humidity sensor. Its RH humidity measurement is based from advanced micro-processing chip and high accuracy humidity element, and industrial class PT100 is used to test temperature value. Its sensing probe is encased in powder metallurgy metal tube which can effectively filter dust impurities. It can probe the probe greatly and ensure a long-term stable performance.

The high temperature humidity sensor is equipped with intelligent temperature compensation for full range humidity measurement. Meanwhile, its probe is encapsulated with sintered metal which can ensure the sensor robust. Its typical temperature range can be -40 -+250℃,and special making available for higher temperature,e.g.300℃ or 600℃.

Our high temperature humidity sensor transmitters have been well sold in the market. It can support outputs of 4-20mA,0-5VDC and RS485.Its main specification can reach the first-level international standard, but comparing with international brand, our price is lower. The sensor is one of the most ideal product for high temperature humidity measurement at present.

The temperature humidity sensors are widely used in the field of flue gas desulfurization, denitrification, high temperature oven, wood drying, food drying, medicine drying, etc, which need to measure high temperature and humidity of the air.

Features:

  • High accuracy, more reliable, long life and excellent performance for humidity measurement
  • Advanced anti-surge power design for voltage and current
  • Optimized algorithm ensures data stability and eliminate signal interference from spot environment
  • Digital linearization correction,high accuracy,high stability.
  • Small size, light weight, anti vibration, flexible installation and easy to use
  • Can make different shape and structure to meet different requirement
  • Piecewise calibration technology for analog output to ensure linear of full range
  • Industrial class electronic components are used to make sensor work for long term under harsh application
  • Unique shifting correction technology can ensure correction after long-term using. This can save huge cost for returning for calibration and improve using efficiency

For high temperature humidity sensor, we mainly have two models: one is flexible type which can supply different options which can reach range of -40-250℃.; the other is explosion-proof type which has one measuring range of -40-200℃.

For high temperature humidity sensor, we mainly have two models: one is flexible type which can supply different options(max temp. up to 250℃), the other is explosion-proof type which has one measuring range of -40-200℃.

High Temperature Humidity Sensor Transmitter

The model can support more flexible features for different options, e.g. it has 3 class of temperature range optional which can reduce some cost for lower temperature. Meanwhile, it has separated type and integrated type optional.

Industrial processes are asking for stricter and stricter requirement for humidity controlling. And our high temperature humidity sensors can ensure good accuracy within the range of -40-250℃. It has been an ideal solution with high cost-effective solution. For industry process controlling, the important application for humidity is typically in the field of drying and freezing.

When Should Select High Temp. Temperature and Humidity Sensor

Common type temperature and humidity sensors usually have max temperature at 80 Deg.C.(this is our product standard),and when temperature is over 80℃. for long-term,e.g. 90℃ or over 100℃ or higher temperature. Under such conditions, it is better to select high temp.temperature humidity transmitter.
