With standard and wide-angle lens choices, plus mounting accessories, it can be tailored for diverse installation needs and delivers reliable data via a 4-20 mA two-wire interface.

FAQ's of ExTempMini Miniature Intrinsically Safe Infrared Temperature Sensor for High Ambient Temperatures:

Q: How does the ExTempMini ensure safe operation in hazardous environments?

A: The ExTempMini is certified as intrinsically safe under IECEx and ATEX standards, making it suitable for explosive zones 0, 1, 2, 20, 21, and 22. Its design minimizes energy storage and restricts current, which helps prevent ignition sources and ensures reliable operation in hazardous areas.

Q: What is the process for installing the ExTempMini sensor?

A: Installation is straightforward thanks to the compact sensor head and available mounting accessories. You can use either an M12 connector or an integral cable for electrical connection. The sensor's IP65-rated housing allows placement in various industrial environments without additional protective enclosures.

Q: When should I consider using the ExTempMini over conventional temperature sensors?

A: Choose the ExTempMini for applications that require non-contact temperature measurement, especially in hazardous or high-temperatures zones where ambient conditions reach up to +180C, and where compliance with IECEx and ATEX is mandatory.

Q: Where can the ExTempMini be deployed for optimal performance?

A: The sensor is ideal for deployment in oil & gas, chemical, pharmaceutical, and food processing industries, particularly in regulated hazardous areas. Its versatility also suits environments with limited access or space, and it can measure process temperatures from -20C to +1000C, depending on the model.

Q: What output and power requirements does the sensor have?

A: The ExTempMini provides a 4-20 mA two-wire current loop output for reliable transmission of temperature readings. It operates on a supply voltage range between 12 and 28 V DC, making it compatible with most industrial control and monitoring systems.

Q: How accurate and repeatable are the temperature readings from this sensor?

A: With an accuracy of 1C or 1% of reading (whichever is greater) and repeatability of 0.5C or 0.5% (whichever is greater), the ExTempMini ensures dependable and consistent measurements, crucial for maintaining process quality and safety.

Q: What are the key benefits of using the ExTempMini in industrial processes?

A: The main benefits include enhanced safety in hazardous zones, reliable accuracy and fast response time, flexibility in installation, and the ability to operate in extreme ambient temperatures without cooling. This all contributes to efficient, safe, and cost-effective process monitoring.
