FAQs
1. What is a Weatherproof RTD Sensor and how does it differ from a Flameproof RTD?
A Weatherproof RTD Sensor is a PT100 Resistance Temperature Detector (RTD) designed for use in non-hazardous industrial environments. It features an IP65-rated die-cast aluminum protection head that protects against dust, moisture, and water splashes. In contrast, a Flameproof RTD Sensor is equipped with an explosion-proof enclosure designed for installation in classified hazardous areas where flammable gases or vapors may be present. Weatherproof RTDs provide a more cost-effective solution when hazardous-area certification is not required.
2. What are the specifications of Aavad’s Weatherproof RTD Sensor?
Aavad’s Model APWS-6-1 is a simplex PT100 RTD Sensor with Class A accuracy and an operating temperature range of -50°C to +400°C. It features a 200 mm SS316 stainless steel probe, a die-cast aluminum protection head with a threaded cap and retaining chain rated IP65, and a ¾" ET cable entry for reliable industrial temperature measurement.
3. Can this Weatherproof Sensor be wired for different instrumentation needs?
Yes. The Weatherproof PT100 RTD Sensor is available in 2-wire, 3-wire, and 4-wire configurations, making it compatible with temperature transmitters, PLCs, DCS systems, SCADA platforms, PID controllers, digital temperature indicators, and industrial automation systems.
4. Is a Weatherproof RTD suitable for outdoor installations?
Yes. The IP65-rated die-cast aluminum head protects the sensor against dust, humidity, low-pressure water jets, and routine wash-down conditions, making it suitable for both indoor and outdoor installations in non-hazardous industrial environments.
5. What applications suit the Weatherproof PT100 RTD Sensor?
Weatherproof PT100 RTD Sensors are widely used in industrial process control, chemical processing in non-hazardous areas, storage tanks, HVAC systems, utility plants, food and beverage processing, packaging machinery, OEM equipment, water treatment plants, and general industrial automation, where reliable and cost-effective temperature measurement is required.
