Product Overview
The Mining Intrinsically Safe Thermal Imaging Camera is manufactured to strict national coal mine safety standards, employing advanced thermal imaging technology to capture clear thermal distribution images even in complete darkness. As a high-performance, high-reliability component of industrial television systems, it provides real-time image monitoring for critical underground and surface mine applications.
Product Description
Thermal imaging is an indispensable technology for mine safety, enabling the detection of thermal anomalies — overheating bearings, electrical faults, spontaneous combustion precursors — that are invisible to conventional visible-light cameras. The Mining Intrinsically Safe Thermal Imaging Camera brings this capability to the most hazardous zones of a coal mine through its intrinsically safe (Ex ib I Mb) certified design, which ensures that the device's circuits cannot generate ignition-capable sparks or thermal effects under any operational or fault condition.
The camera's thermal imaging capability covers a temperature range of 0 °C to 150 °C, enabling detection of both normal operational temperatures and dangerous thermal excursions. In environments with insufficient visible light, the camera's micro-light visible imaging and infrared auxiliary illumination ensure that clear black-and-white images can be captured even in absolute darkness. The multi-channel image preview function provides flexible switching and synchronized display between thermal and visible-light feeds, giving operators both thermal analysis and visual context simultaneously.
The intelligent over-temperature alarm function is a critical safety feature. When detected temperatures exceed pre-configured thresholds, the camera automatically triggers voice alarms and/or switch-signal linkage, enabling immediate response to potential fire hazards, equipment overheating, or spontaneous combustion events. The network audio reception and playback function supports remote voice projection and emergency broadcast capabilities, allowing control-center operators to issue verbal warnings to personnel near the monitored location.
The device is built for the underground environment with a 304 stainless steel housing and IP65 protection rating. It features three TCP/IP full-duplex 100 Mbps Ethernet electrical ports and two 1310 nm single-mode fiber 100 Mbps Ethernet optical ports, providing flexible network connectivity options. Four switch-signal inputs and four relay outputs (DC 12V/1A) enable integration with external alarm and control systems. The sound-level intensity of ≥85 dB(A) ensures that audible alerts are clearly perceptible. With a maximum operating current of ≤1.4 A at 12 V DC, a horizontal resolution of 400 TVL, and a minimum illumination of ≤0.05 Lux, the camera delivers high-quality imaging across its operating envelope.
