0911472255The TSM-Atex Series ATEX Explosion-Proof Temperature Switch & Sensor is engineered and manufactured by Bühler Technologies GmbH – a premier German technology company globally recognized for advanced fluid control systems and industrial process automation. The TSM-Atex series is specifically developed to comply with the most stringent explosion protection safety regulations (ATEX Directive 2014/34/EU) for fluid temperature measurement, limit monitoring, and thermal alarm signaling inside hazardous operating environments where flammable gases, vapors, or mists are present.
In hydraulic power packs, lubrication systems, and chemical storage reservoirs, unexpected fluid temperature spikes indicate mechanical friction, system overloading, or fluid degradation. In explosive atmospheres, unmonitored excessive thermal levels pose severe ignition hazards. The Bühler TSM-Atex sensor resolves these operational risks through highly sensitive temperature detection elements (precision PT100/PT1000 RTDs or bimetallic switches) housed within heavy-duty explosion-proof enclosures.
Key technical highlights of the Bühler Technologies TSM-Atex:
- ATEX Explosion-Proof Safety Certification: Tested and certified for safe operation in hazardous Ex-Zones (Zone 1/2 or Zone 0/1 depending on Ex-i / Ex-d protection concept), eliminating spark risks or excessive surface temperatures that could ignite surrounding flammable atmospheres.
- High-Grade Chemical-Resistant Construction: Thermowells and sensor housings are fabricated from 316L Stainless Steel (1.4571) or precision-machined Brass, providing exceptional chemical resistance against mineral-based hydraulic oils, synthetic lubricants, solvents, and liquid fuels.
- Versatile Measurement & Switching Options: Supports bimetallic thermal switch contacts (preset switching thresholds at 50°C, 60°C, 70°C, 80°C) or continuous PT100 RTD resistance elements (2-wire/3-wire) transmitting analog signals (4-20mA) to central PLC automation networks.
- Heavy-Duty IP65/IP67 Enclosure Rating: Explosion-proof junction boxes securely seal electrical wiring against ingress of dust, moisture, and corrosive chemical vapors in demanding outdoor or indoor industrial plant conditions.
The Bühler TSM-Atex ATEX Temperature Sensor is an essential safety component across oil refineries, fuel distribution depots, chemical processing facilities, heavy-duty industrial hydraulic power units, thermal power stations, and manufacturing plants requiring certified Ex safety.
