YXG-100-B YXG-150-B Explosion proof Induction Contact Pressure Gauge

The instrument is designed for use in places where there is a risk of combustible media and explosive mixtures in the surrounding environment. It measures the pressure of liquids and gases and has functions such as automatic control and automatic alarm. The instrument adopts a contactless induction switch, which has high safety and reliability.   

The instrument is manufactured in accordance with GB3836.1-2000 "Electrical Equipment for Explosive Gas Environments Part 1 General Requirements" and GB3836.4-2000 "Electrical Equipment for Explosive Gas Environments Part 4 Intrinsic Safety Type" i ". After inspection by the national level instrument explosion-proof safety supervision and inspection station, the explosion-proof safety performance meets the standard requirements of GB3836.1-2000 and GB3836.4-2000. The explosion-proof certificate number is GYB03196. Instruments must be used in conjunction with safety barriers (recommended to use WE77/EX2 or WE77/EX1 safety barriers - explosion-proof control units produced by German P+F company) to form an intrinsic safety explosion-proof system before they can be used in places where explosive gas mixtures below Class IIC are present on site.

Point type and method: Table 1

model	schematic diagram	Contact type	The position of the control panel when it changes with the indicator needle	Equivalent contact point
YXG-□-B21		Upper and lower limits	1. The control panels are all located inside the induction switch. 2. When the indicator needle moves up (or down), the control chip of the upper limit contact (lower limit contact) exits the sensing switch	1. Both contacts are disconnected. 2. Connect the upper limit contact (lower limit contact)
YXG-□-B11		Double upper limit	1. The control panels are all located inside the induction switch. 2. When the indicator pin goes up, the control pads of contacts 1 and 2 exit the induction switch in sequence	1. Both contacts are disconnected. 2. Connect contacts 1 and 2 in sequence
YXG-□-B22		Double lower limit	1. The control panels are all located inside the induction switch. 2. When the indicator pin descends, the control pads of contacts 2 and 1 exit the induction switch in sequence	1. Both contacts are disconnected. 2. Connect contacts 2 and 1 in sequence.
YXG-□-B1		Single upper limit	1. The control panel is located inside the induction switch. 2. When the indicator pin goes up, the contact control piece exits the induction switch.	1. The contact is disconnected. 2. Connect the contacts.
YXG-□-B2		Single lower limit	1. The control panel is located inside the induction switch. 2. When the indicator pin descends, the contact control piece exits the induction switch.	1. The contact is disconnected. 2. Connect the contacts.
Note: In the diagramThe control chip is inside the induction switch, and the indicating contact is in a disconnected state (contact current ≤ 1mA) The control panel is located outside the induction switch, and the indicating contact is in a connected state (contact current ≥ 3mA) 100, 150

Note:
1. The connecting cable between the instrument and the intrinsic safety end of the safety barrier must be a shielded cable (with insulation sheath), with a cross-sectional area of each core wire>0.5mm2, and its shielding layer should be grounded in a safe place. Cable wiring should eliminate the influence of electromagnetic interference as much as possible, and ensure that the distributed capacitance of the cable is less than 0.2 μ F and the distributed inductance is less than 2mH.
2. Users are not allowed to replace product components on their own.
3. When using this instrument in non explosion proof areas, it can be equipped with the YXG-K controller produced by our factory.
