Special human body electrostatic discharge alarm in chemical plant is introduced in detail

Chemical factory dedicated human body electrostatic discharge alarm ET-PSA type human body electrostatic discharge alarm apparatus is Ji'nan safero Instrument Company Limited (Tel: 13021732250 contact: I wish the manager) for a new generation of explosion-proof products in petrochemical industry design, it can intelligently detect the human body static voltage is guided in finished, when the body is in danger when the value of static voltage audible alarm.

It adopts special conductive plastic material, prolong the electrostatic discharge time, safe release of electrostatic energy, electrostatic discharge in the body, to ensure that no inductance, no sparks, completely eliminates the electrostatic fire accident

At present, some flammable and explosive dangerous places are still using metal conductor grounding discharge way to eliminate the human body static electricity,

Although this approach can eliminate the human body, but the way the conductor between the discharge form release of electrostatic charge, electrostatic release resistance is small, the release time is short, the instant release of energy, which leads to the inevitability and possibility of human electric or fire accidents.

ET-PSA human body electrostatic discharge alarm for the current human body static removal methods of the lack of reasonable human body electrostatic discharge resistance, prolong the human body electrostatic discharge time, reduce the human body electrostatic energy release, effectively avoid the occurrence of fire accidents and the human body is like playing electric. At the same time, ET-PSA human body electrostatic release alarm touch sensor and touch the ball touch the reliable, no active mechanical components, sound and light alarm prompt whether the release of static electricity is completed.

Characteristics of the human body electrostatic discharge alarm (ET-PSA)

1 ultra low power design, without the need to replace the battery during normal use;

2 touch sensing, no mechanical moving parts;

3 integral epoxy resin casting, anticorrosive, waterproof, moisture proof;

4 explosion-proof touch ball, safe release of static electricity, the human body contact does not generate electricity to fight flu;

5 sound and light alarm, real-time indicating equipment working state, easy to use;

6 independent grounding detection, grounding resistance less than 55 ohm, ensure reliable grounding

Suitable occasion:

1, gas station unloading mouth;

2, the entrance of the storage area and storage tank on the upper tank of the escalator mouth;

3, pump room door;

4, oil platform;

5, beside the self-service tanker;

6, the other to eliminate the human body electrostatic places, such as electronic factory, computer room, chemical plant entrance etc..
