1、 Meaning
SHC-600 Absolute Temperature and Humidity MeterUnder standard conditions(760mmHg)per cubic meterwet airThe weight of water vapor contained in it, i.ebulk density.ρ=2.169P/(273.15+θ)(1)In the formula,ρFor absolute humidity(g/m3)Among themPIs the vapor pressure of water, in unitsPa.
2、 Introduction
split type(i.e. the sensor sensitive element and transmitter are separated into two parts)Temperature and humiditySensor, Sensingimplement become differentThe connection between transmitters can achieve long-distance transmission. connection50Connect with ordinary wires within meters. connection 50For meters and above, please use a single shielded wire connection (with each wire shielded).
The split type temperature and humidity sensor is currently one of the most ideal products for relative humidity environment testing. Using imported chips to ensure good linearity of full-scale analog output, high precision, strong stability, good consistency, long service life, distortion free long-distance transmission, fast response speed, temperature compensation for humidity testing, and synchronous sampling of temperature and humidity signals.
3、 Application Fields
This product is suitable for temperature and humidity measurement and control fields in industry, agriculture, healthcare, and scientific research, meeting the requirements of a wide range of users. When used in special environments such as high and low humidity, high and low temperature, it can better demonstrate its unique superior performance. Can be matched with computer systems and secondary instruments, easy to use, and easy to connect.

1. For harsh environmental conditions such as high temperature, high humidity, etc., it is not suitable to place the transmitter (electronic device). A two-piece set can be used to extract the sensor part from the housing. The sensor part can be placed in the environment to be measured, and the transmitter can be placed at the measurement and control equipment. When connecting sensors and transmitters with wires, there are two wires for relative humidity and two wires for temperature If choosing a new form of two-piece set, it is necessary to inform the manufacturer in advance.
2. split typeSuitable for: cement curing, wood drying, tobacco, building materials, flower workshops, chimney ventilationroadWaiting for special environments and equipped with special probes.
5、 Precautions
1. This sensor can only be used at -40 ℃-Frequently used in a temperature environment of 125 ℃.
2. This sensor is not suitable for use in environments with long-term condensation and severe chemical pollution.
3、When not in use, this sensor should be stored in a dry environment.
When the sensor has oil stains, it can be usedindustrial alcoholclean.
