The HPM288 Anti-explosion Pressure Transmitter utilizes a high-performance silicon piezoresistive pressure core. Equipped with an AISC (Analog Integrated Signal Converter), it efficiently converts the transmitter signal into a standard long-distance current. This allows for convenient connection with computer interface cards, control instruments, intelligent instruments, or PLC systems.

This series of products finds wide applications in industrial process control, as well as industries such as petroleum, chemical, metallurgy, and mining. It complies with the standards GB3836.1-2010 (Explosive Atmosphere Part 1: General requirements for equipment) and GB3836.2-2010 (Explosive Atmosphere Part 2: Equipment protected by flameproof enclosure "d"). The explosion-proof marking is Exd II CT6.

The HPM288 Anti-explosion Pressure Transmitter can operate reliably under specific conditions. It can work at altitudes below 200 meters, in ambient air temperatures ranging from -10℃ to +60℃, and in an environment with a relative humidity of 90% (+25℃).

With its robust design and compliance with explosion-proof standards, the HPM288 Anti-explosion Pressure Transmitter is a reliable solution for various industries operating in potentially hazardous environments.
