Sealing means of the humidity sensor, for the protection of the measurement accuracy and stability

Humidity sensor non-sealing, to protect the measurement accuracy and stability, should be avoided in acidic, alkaline, and an atmosphere containing organic solvents used. Also avoid the use of larger dust environments. Space to be measured as accurately reflect the humidity sensor should be placed to avoid too close or away from the wall of the dead at the air does not circulate. If the measured room is too large, it should place multiple sensors. Some of the humidity sensor on the power supply requirements are relatively high, otherwise it will affect the measurement accuracy. Mutual interference between Camshaft Position Sensor or even not work. Should be used in accordance with the technical requirements to provide appropriate and meet the accuracy requirements of the power supply. Sensors will require long-distance signal transmission, pay attention to the signal attenuation problem. When the transmission distance of more than 200m above, suggested the use of the frequency of the output signal humidity sensor. In addition, there are some selection criteria, the use of different temperature and humidity measuring principle, temperature and humidity meter varied to be considered in the selection of the user's actual application environment and requirements, such as range, output and display, installation, sampling methods, gas type, materials and structures, control monitoring requirements, and other environmental hazards. Positioning Sensor network of experts to provide Honeywell Relative humidity / temperature sensor and relative humidity sensors are used to provide on-chip containing a signal conditioning functions integrated circuits. This series of Motor Sensors installed in the thermosetting resin having a polymerization capacitive sensing diaphragm in vivo, interact with the platinum electrode. The use of laser correction of sensor has strong stability and low drift characteristics, with an accuracy of +5% relative humidity. Best use of the environment: Absorption humidity sensors can provide temperature and% RH (relative humidity) output. On-chip signal processing functions can be guaranteed with a relative humidity corresponding linear voltage output. Sensors Laser amended to an accuracy of + 5% relative humidity, calibration accuracy up to 2% relative humidity. The product packaging can be protective chemicals, operating temperature range is -40 ℃ ~ 85 ℃ (-40 degrees to 185 degrees F), in harsh work environments.
