YTX-B series explosion-proof electric contact pressure gauge

◆ Model: YTX100B YTX150B

◆ Uses: This series of instruments is specially used in the surrounding environment of combustible media and explosive mixture danger of places, measuring the pressure of liquids and gases, with the corresponding electrical devices, can achieve alarm or automatic control and other functions.

The instrument adopts a magnetic electrical contact, which has the characteristics of large suction force and reliable contact.

This instrument complies with the requirements in GB 3836.1-2010 "Explosive atmospheres – Part 1: General requirements for equipment" and GB3836.2-2010 "Explosive atmospheres – Part 2: Equipment protected by flameproof enclosures "d".

This instrument is installed in a place where there is an explosive gas mixture of class II or less on site. However, the installation site should be free of gases that do not corrosive to the product shell.
