CE ATEX certificates NH3 ammonia gas alarm detector with 4-20mA RS485 Modbus signal output
Показать описание
If you’re interested in our product Nh3 Ammonia Gas Leak Detector, please view at:
Industrial ammonia transmitter through continuous online detection of ammonia NH3 gas in the atmosphere and sound and light alarm, not only plays a role in controlling the concentration of gas in special occasions, but also has a warning effect on the dangerous scene gas leakage, and timely protects the life and property safety of various sites. Instruments are widely used in petroleum, chemical industry, metallurgy, fire protection, coal mine, electric power, shipping, environmental protection, telecommunications, medical and other industries. IDG100 series on-line ammonia NH3 detector adopts imported sensors combined with high-speed, high-precision processing circuit, with signal stability, high precision, good repeatability, and explosion-proof design, suitable for all kinds of dangerous situations. Instrument output a variety of standard signals, can be compatible with a variety of alarm systems, PLC, DCS and other control systems.
This video shows details of our fixed LCD display single gas detector and how is it working,it uses high precision and fast response sensor,LCD large screen shows gas name,unit,concentration and time in real time,DC12-36V working power,supports 4-20mA and RS485 Modbus signal output,both signal output can be done at the same time,this style can save 3000 alarm records,remote control key design,easy to set parameters,it usually use together with gas alarm controller, of course you can install gas detector with alarm only,or connect with your PLC,DCS etc.Application Temperature range is - 20 ℃～ 50 ℃,Humidity range is 15% ～ 90% (RH), non-condensing.
1.Fixed description
Wall mounted type: draw the installation hole on the wall, use 8mm × 100mm expansion bolt, fix the expansion bolt on the wall, install the transmitter, and then fix it with nut, elastic pad and flat pad, as shown in Figure 2.
After the transmitter is fixed, remove the upper cover and lead in the cable from the inlet. Connect the terminal according to the positive and negative polarity (Ex type connection shown in the diagram) as shown in the structural drawing, then lock the waterproof joint, and tighten the upper cover after all links are checked to be correct.
2.Wiring instructions
2.1 RS485 mode
(1) Cables shall be rvvp2 * 1.0 and above, two 2-core wires or rvvp4 * 1.0 and above, and one 4-core wire.
(2) The wiring only supports hand-in-hand method.
(3) It can be connected to bus control cabinet or PLC, DCS, etc. Modbus communication protocol is needed to connect PLC or DCS.
2.2 4-20mA mode
The cable shall be RVVP3 * 1.0 and above, 3-core wire.
3.Operating instructions
The instrument can display at most one gas value index. When the index of the gas to be detected is in the alarm range, the relay will be closed. If the sound and light alarm light is used, the sound and light alarm will be sent out.
The instrument has three sound light interfaces and one LCD switch.
The instrument has the function of real-time storage, which can record the alarm status and time in real time.
4. Menu instruction
When the user needs to set parameters, press the middle key.
Functions:
Time set: Set time setting
Communication settings: Communication baud rate, device address
Alarm store: View alarm records
Set alarm data: Set the alarm value, the first and second alarm value
Calibration: Zero calibration and calibration of instrument
Back: Return to the detection gas display interface.
5.Attention
(1). Avoid using the instrument in corrosive environment
(2). Be sure to avoid contact between the instrument and water.
(3). Do not wire with electricity.
(4). Regularly clean the sensor filter to avoid the filter clogging and unable to detect gas normally.
HCL, ETO and other sensors need to be aged for 24-48 hours after being powered on before the value can be reduced to normal,During this period, the instrument may always be in alarm state.
If the above problems cannot be solved, or the zero point shifts after long-term use, and other problems, please contact our company to provide solutions according to specific conditions.
