High temperature 260 ℃ wall mounted temperature and humidity sensor

High temperature 260 ℃ wall mounted temperature and humidity sensor

1overview

Our company's resistive humidity sensor, After years of research and development practice,Has * * temperature and moisture resistance.

Can be found on-70—260℃Within the temperature range of the environment, answer1%---98%RHMeasure the temperature and humidity of the process environment within the range of environmental humidity.

Beiyou has high precision, superior repeatability, and stable long-term use, And the product has a long lifespan, Up to three years or more(Guaranteed for one year).

When in use, Simply place the temperature and humidity sensor, the size of a cigarette, directly into the exhaust duct, drying kiln, battery curing room, or food baking oven…. . Waiting for high temperature,Places where temperature and humidity need to be measured.

The measured signal is obtained from the sensor,High temperature resistant and flame-retardant cable lead out, Connect to temperature and humidity measuring instruments through transmitters that are compatible with sensors,On temperature and humidity measurement control instruments or temperature and humidity measurement recorders.(Our company has products available for all three types of instruments and can provide matching services)

temperature and humiditymeasureDisplay instrument,Display temperature and humidity.

temperature and humiditymeasurecontrolmeter,Set the upper and lower limits of temperature and humidity, and if they exceed the limit, output a switchsignalOr analog electrical signal,Controllable opening or closing: heater(Heating up), Refrigerator or fan(lower the temperature), humidifier(humidification), dehumidifier(Dehumidification).

Temperature and humidity recorder, From once per second to once per hour(Can choose to set up), Automatically record and display, Temperature and humidity during measurement, Data and Curve Chart, The recorder can monitor simultaneously1-4Points, 1-8Points, 4-16Points, 16-40Temperature and humidity at a certain point(Each point needs to be equipped with a temperature and humidity sensor).

According to user needs, the recorder can be configured with:Set the upper and lower limits of temperature and humidity, and if it exceeds the valueOUTPUTsignalOr analog electrical signal,Can control the opening or closing of related electrical appliances.

In industrial production and experimental processes, this product is widely used in high-temperature drying and aging, low-temperature and high humidity experiments, and storage fields. for example: Measurement and control of temperature and humidity in industries such as factory exhaust ducts, kilns, battery curing rooms, food baking ovens, meteorology, environmental protection, cement maintenance, electricity, desulfurizers, pharmaceuticals, textiles, chemicals, metallurgy, feed, low-temperature and high humidity storage, wood, and wine industry.

4、 Installation steps:

1. Probe usedM27*2The installation thread or outer diameter is68mmPlastic or cast aluminum movable flanges are fixed on walls or pipes

(Optional thread or

2Connect the transmitter cable to the acquisition device.

Installation position：

1The transmitter should be placed vertically as much as possible, and during installation, ensure that the sensor is on top of it

The font should be in the positive direction to ensure that the sensor is located below the transmitter;

2The installation height is the height of the human body sitting or the main environmental area that requires measurement

Installation precautions：

1Avoid generating temperature in areas that are easy to transfer heat and directly affect the test area

Installation in poor areas may result in inaccurate temperature and humidity measurements.

2Install in a stable environment area. Avoid direct sunlight, stay away from windows, air conditioning, heating and other equipment, and avoid facing windows or doors directly.
