How to install a gas detector? What are the considerations for installing a gas detector?

<

Gas detector is a commonly used gas concentration detection instrument, which is suitable for hazardous locations with flammable or toxic gases. It is widely used in petroleum, chemical, steel, coking and other fields. Gas detectors should be how to install it? The following Xiaobian to specifically introduce the gas detector installation method, I hope to help everyone.
Gas detector installation method The first step is to install the gas detector in the area where there may be gas leakage. The installation of the gas detector must be firm, and the installation position is determined according to the proportion of the gas to be measured relative to the air. Less than air, c should be installed 30 to 60cm from the ceiling. Secure the detector to the wall with a φ8 expansion screw.
In order to properly use the detector and prevent its failure, do not install in the following locations:
a. Directly affected by steam and fumes

b. Air flow, ventilation fan, door, etc.

c. Where there are many vapors and water droplets (relative humidity: more than 90%)

d. Temperature below -40°C or above 70°C

The second step is wiring: the wiring should use a highly shielded wire to prevent the electrical signal from being disturbed. Place the wire well and open the top cover.
1. Gas detectors generally use three-wire transmission. The positive terminals of the power supply are marked with "VCC" terminals, the signal lines (terminals marked with "sig"), and the negative terminals of the power supply (terminals marked with "GND"). Connect the 24v, ma, and gnd of a group of terminals labeled “4-20main” to the channel module. The chassis ground (shielding mesh of the cable) is well grounded. After the cable is connected, fasten the chassis.
2. Start: Wiring is completed and the detector is powered. The reading will be stable from the over-range reading to just about 15 minutes after the start.

Corn protein powder is the by-product of starch factory after produced corn starch. Its raw material is corn, by peeling, crashing, deslagging, and extracting starch and then concentrate, dried the yellow water to get protein products. It contains a lot of lutein that has golden color. It is good at encourage and disease-resistant for livestock and poultry. It also can deepen the egg`s color, make chicken`s skin and legs become yellow, and contain rich amino acids. It is a good additive for animal husbandry and feed industry.
