Earthing clamp with visual indication

The accumulation of static charges during the fueling transfer process can lead to costly explosions, fire and personnel injury. The ‘Self-testing Grounding Clamp’ with visible & audible alarms is designed to dissipate static accumulation and verify proper grounding. Earthing clamp with visual indication is intrinsically safe for use in hazardous locations.

1. Low energy consumption design of Self testing clamps with visual indication makes battery replacement unnecessary during normal operation. 

2. Audible and visible alarms 

3. Digitron resistance display 

4. After 1 minutes' continuous alarm it will be in the resting status and it will return to normal in a closed circuit. 

5. Circuit part is totally enveloped by epoxy resin which makes it damp-proof, rustproof, erosion-proof and shock-proof. 

6. The static grounding clamp can penetrate the paint and rust and insure the bodywork is effectively grounded.

7. It insures the resistance between the tanker truck and the ground stud not bigger 10Ω (meeting the state standard of less than 100Ω).

8. The coat of the ground cable is made of special rubber with the characteristic of high or low temperature-proof, corrosion-proof and oil-proof.

9. The standard cable length is 5 m. Other length is available upon request.
