Industry explosion proof limit switch class 1 division 2 hazardous area
Description:
The explosion-proof limit switch is a kind of field instrument for the valve position display and signal feedback of the automatic control system. It is used to output the signal of the valve's apocalypse or production and closure position with the amount of the day off (contact), and is accepted by the program or computer. After confirmation, execute the next procedure. The product can also be used as an important in the automatic control system, valve interlock protection and remote alarm indication, and can form a complete signal control and return function with the explosion-proof valve control box.
Feature:
1. The three-dimensional position indicator clearly shows where the valve is.
2. Die-cast aluminum alloy shell, powder coating, compact design, beautiful appearance, reducing valve packaging volume and reliable quality.
3. Two-wire interface double 1/2 NPT pipe interface.
4 signal feedback device.
5. The switch position can be clearly identified by the indicator.
6. Multiple contacts are connected inside the circuit board with 8 contacts (6 for the switch and 2 for the spiral conduit). The terminal block meets the standard of the micro switch.
