WE-T130 Explosion-proof Pressure Monitoring Transmitters

The transmitter body adopts LoRa type, supports the frequency band range of 410MHz~490MHz, and supports SMA antenna interface; The 4G type supports full Netcom communication;
The transmitter communicates with the edge computing gateway of Shidian Technology through the WES-WIO wireless terminal communication protocol to realize real-time reporting of on-site pressure and status detection data.
External pressure probe, pressure detection range and installation method can be selected and customized;
Support 0~1.6MPa conventional pressure range, other ranges can be customized;
Support different levels of accuracy pressure probes to meet different accuracy requirements;
Support straight pipe, thread and other installation methods;

WE-T130 is a series of explosion-proof pressure monitoring transmitters, including LoRa, RS485, 4G, etc., and battery power supply and 24V power supply. The pressure transmitter uses high-stability digital sensors to realize real-time monitoring and calculation of on-site pressure, and uses LoRa, RS485, 4G and other communications to achieve long-distance communication.

The integrated design of the transmitter body and the probe provides a variety of pressure ranges and installation specifications for the different needs of the measured medium, pressure range, and installation method on site, which can be widely used in construction buildings, industrial sites, municipal and other application scenarios.

The explosion-proof type is a flameproof transmitter, which complies with the provisions of GB3836.1-2010 and GB3836.4-2010, and the explosion-proof mark is Exib IIBT4.
