Explosion-Proof Signal Lightning Protector D48Y2-T-1 2 NPT

Explosion-Proof Signal Lightning Surge Protector

Name: Explosion-Proof Signal Lightning Surge Protector
Brand: Shenzhen Techwin Lightning Technologies Co., Ltd.

The product mainly provides perfect protection for on-site 2-wire, 3-wire and 4-wire instruments to prevent them from damage caused by lightning induction, voltage and power supply interference, and electrostatic discharge. The lightning protection device is encapsulated in a 316 stainless steel casing, and can provide 1/2"NPT, M20*1.5, PG13.5, G1/2 and other threaded line interfaces. The lightning arrester is connected in parallel with the signal system, and there is almost no additional loss to the signal. It can be used for FF bus, PROFITBUS-PA, and WorldFIP systems, and is suitable for instruments with HART protocol, 4-20mA analog signals, 2/3/4-wire transmitters, thermal resistors, switch quantities, digital communications RS-485, RS-232, RS422, flow meters, solenoid valves, etc., without affecting the normal communication of signals. It is widely used in petroleum, chemical, natural gas, environmental protection, new energy and other industries.
