The HRP-T1000-A is a fixed monitoring device specifically designed for flammable gas leaks in industrial sites. It enables 24-hour continuous and accurate monitoring, tiered early warning, and remote centralized management to prevent explosions and ensure industrial production safety. Achieving "real-time monitoring, tiered early warning, remote networking, and stable operation," it serves as a core line of defense for ensuring production safety and preventing explosions in high-risk industries such as petrochemicals, gas, and metallurgy.

It features a standard 4-20mA/RS485 signal output and can be integrated into existing systems as a modular device.

1.Real-time monitoring and active early warning
The fixed gas detector can continuously monitor the gas concentration in a specific area 7x24 hours a day. Once the concentration of flammable or toxic gas is detected to exceed the preset safety threshold, the equipment will immediately trigger an audible and visual alarm, and the alarm signal can be transmitted to the monitoring center remotely. This active early warning mechanism has won valuable time for personnel evacuation and emergency treatment, and effectively prevented the occurrence of vicious accidents such as poisoning, fire and explosion.
2.Strong and durable, adapt to harsh environment.
This kind of equipment is specially designed for harsh industrial environment, and usually adopts a solid explosion-proof shell (such as aluminum alloy or stainless steel), with high-grade explosion-proof certification (such as Exd IIC T6) and protection grade (such as IP66/IP67). This enables it to withstand harsh working conditions such as high temperature, low temperature, high humidity, dust and corrosion, and ensures long-term stable operation in dangerous places such as petroleum, chemical industry and metallurgy.
3.Highly intelligent, integrated linkage
Modern fixed gas detector integrates advanced microprocessor and intelligent sensing technology. They not only have the functions of automatic calibration, fault self-diagnosis, data recording, etc., but also can be linked with external equipment such as fans, cut-off valves and spray systems through 4-20mA, RS485 and other signal outputs. When leakage occurs, the system can automatically start emergency measures to realize intelligent safety management from passive monitoring to active disposal.
4.Improve efficiency and reduce comprehensive cost.
The fixed detector can replace the traditional manual inspection and realize unattended continuous monitoring, thus saving a lot of labor costs. At the same time, it can help enterprises meet the increasingly stringent requirements of safety production laws and regulations, and avoid the high fines and the risk of suspension of production and rectification caused by illegal operations. In addition, continuous safety monitoring helps to reduce the insurance premium rate and prolong the service life of key production equipment.
5.Data traceability, supporting decision-making.
The equipment can automatically store a large number of historical data, including alarm records, fault information and concentration change trends. These data can be viewed through the local screen or uploaded to the host computer system, which provides strong data support for accident cause analysis, process optimization and safety management decision-making, and helps enterprises to achieve more refined operations.

  • LED-Display-Screen

LED Display Screen(Optional, not required):

This gas concentration monitoring display screen features a dual-color display and connects to the host computer via RS485 protocol. It is primarily used to display real-time concentration data for various gases. The font colors differ between alarm and normal states. Normal state text is blue, while alarm state text is red.

  • Mounting-Bracket

Mounting Bracket(Optional selection):

High-strength metal mounting brackets are specifically designed for mounting gas monitors and actuators, and are typically used for wall-mounted installations.

  • Calibration-Hood

Calibration Hood(Optional selection):

This is a standard calibration cover specially designed for HIREP series fixed gas detectors, which is used for fast and accurate gas concentration calibration and sensor testing on the equipment site. It has simple structure and good sealing performance, which ensures that the gas can evenly cover the sensor probe during calibration and avoid external interference.

  • Sampling-Tube

Sampling Tube(Optional):

The sampling tube is made of polytetrafluoroethylene (PTFE), which is resistant to high temperatures and corrosion. It is usually used in conjunction with an external pump to safely and stably deliver the gas to be tested in the environment to the sensor analysis unit. It is suitable for remote sampling, detection in confined spaces, or gas monitoring under complex working conditions.

  • Explosion-Proof-Cable-Gland

Explosion-Proof Cable Gland(Optional):

Used for the safe wiring connection of fixed gas detector, alarm host or electrical equipment in explosive environment. Its structure conforms to international explosion-proof standards, ensuring reliable sealing and electrical isolation in flammable and explosive gas environment and preventing accidents caused by sparks or high temperature.

  • Rain-cover

Rain cover(Optional):

Prevents rainwater, dew, and spray water from entering the detector housing, circuitry, and sensor cavity, preventing short circuits due to moisture on the circuit board, reducing rainwater corrosion, and minimizing aging damage to the detector housing and probe caused by ultraviolet radiation. Significantly improves equipment durability, especially suitable for outdoor, open-air, and factory outdoor installation scenarios.
