YT-98H/YT-98H-A Fixed Gas Detector
The YT-98H is a built-in pump-suction single and multi-gas detector 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 industries. Beyond standard 3-wire 4 to 20-mA output with relays, it supports HART and Modbus protocols for compatibility with most control systems. Optional wireless functionality enables remote data viewing on laptops, mobile phones, or cloud systems.
Equipped with a high-suction, long-life vacuum pump rated for over 12,000 hours of continuous operation, this detector offers faster response times compared to traditional diffusion sampling. It can be installed in normal open areas or underground confined spaces to monitor gas concentrations at high altitudes, effectively protecting maintenance personnel safety.
Display & Interface Features
2.4-inch high-definition color screen with simulated menu icons and switchable Chinese/English interface. Capable of detecting up to six gases simultaneously with configurable high/low alarm values and unit switching capability.
Control & Output Options
Infrared remote control allows operation without opening the cover. Standard outputs include three-wire 4-20mA, RS485, and one relay output (up to two optional). External sound and light alarm does not occupy relays. Optional outputs include 0-10V, 0-5V, and 1-5V.
Protection & Safety Features
Explosion-proof, lightning protection, anti-static, surge protection, waterproof with IP65 protection level. Optional accessories: sound and light alarm (integrated or external), water vapor filter cartridge, automatic dehumidification drainage systems, and high-temperature flue gas pretreatment systems.
Wireless Transmission Options
Wireless transmitter and receiver options (2km, 5km, 8km unobstructed), 2G/4G wireless signal transmission (unlimited distance with mobile or data cards). Data monitoring cloud platform enables remote server access with multi-user management, record storage, and real-time viewing capabilities.
