Description
This is Aavad’s flameproof-enclosure temperature controller — a single-loop control instrument certified by CMRI (Central Mining Research Institute) for installation directly inside classified hazardous zones, rather than being panel-mounted safely outside them. The universal input accepts RTD or thermocouple signals as factory-programmed, with a choice of relay or 4-20mA retransmission output (consult factory to specify which at order time). Five cable entries accommodate input, output, and power wiring separately within the flameproof housing, and the ±0.25% of full-scale accuracy holds through a 0-55°C ambient range at up to 95% humidity.
Key Features
-
CMRI Certified Flameproof Enclosure Officially tested and certified by the Central Mining Research Institute (CMRI) for safe operation in hazardous, explosive gas, and vapor atmospheres.

FAQs
1. What is a Flameproof Temperature Controller?
A Flameproof Temperature Controller is an industrial temperature control instrument housed inside a certified flameproof enclosure, specifically designed for operation in hazardous industrial environments where flammable gases, vapors, or explosive atmospheres may be present. It provides accurate and reliable temperature control while complying with hazardous-area safety requirements.
2. What is the advantage of a Flameproof Enclosure?
A flameproof enclosure is engineered to contain any internal ignition or explosion and prevent it from igniting the surrounding hazardous atmosphere when installed and operated in accordance with its certification and applicable safety standards. This enhances personnel safety and protects equipment in hazardous process environments.
3. Can Aavad customize Hazardous-Area Instrumentation?
Yes. Aavad Instrument Pvt. Ltd. manufactures and customizes a wide range of hazardous-area instrumentation, including flameproof temperature sensors, RTD sensors, thermocouples, temperature transmitters, flameproof temperature controllers, and industrial automation solutions to meet specific application and certification requirements.
4. Why choose Aavad Instrument’s Flameproof Temperature Controller?
