Product Overview
The YT-98H/YT-98H-A Fixed Gas Detector is a built-in pump-suction single and multi-gas detection system with IECEx and ATEX certification. Featuring non-contact magnetic wand design, it can be safely installed and operated in explosion-proof areas and Oil & Gas industry applications. In addition to a 3-wire 4 to 20-mA output with relays, it also offers HART and Modbus protocols, ensuring compatibility with most control systems. Optional wireless functionality allows operators to view data remotely on laptops, mobile phones, or cloud systems.
Built with a high-suction, long-life vacuum pump that provides over 12,000 hours of continuous operation, this detector offers faster response times compared to traditional diffusion sampling methods. It can be installed in normal open areas or underground restricted confined spaces to detect gas concentrations at high altitudes, effectively protecting maintenance personnel safety.
The 2.4-inch high-definition color screen features simulated menu icons with switchable Chinese and English interfaces. Capable of detecting up to six gases simultaneously, the system allows for customizable high and low alarm values and unit switching.
Infrared remote control enables operation without opening the cover. Standard outputs include three-wire 4-20mA, RS485, and one group of relay output (up to two groups optional). External sound and light alarm functions do not occupy relays. Optional outputs include 0-10V, 0-5V, and 1-5V.
The detector is explosion-proof, lightning-protected, anti-static, surge-protected, and waterproof with IP65 protection rating. Optional features include sound and light alarm (integrated or external), water vapor filter cartridge, automatic dehumidification drainage system, manual drainage dehumidification filtration system, and high-temperature flue gas pretreatment system.
Wireless transmission options include transmitter and receiver (2km, 5km, 8km unobstructed) and 2G/4G wireless signal transmission (unlimited distance with mobile phone card or data card). The data monitoring cloud platform enables remote data reading from servers, allowing multiple users to simultaneously manage, read, store records, and view real-time data.
