Description
Endress+Hauser TM311: Compact Hygienic Temperature Probe
The Endress+Hauser TM311: Compact Hygienic Temperature Probe is engineered for precise and rapid temperature measurements in demanding hygienic and aseptic applications. Its compact design, coupled with advanced TipSens technology, ensures excellent process control even in tight spaces. This versatile RTD (Pt100) sensor offers a 4-wire connection and is compatible with various smart transmitters, delivering outputs like 4 to 20 mA and IO-Link, making it a foundational component for driving plant standardization in critical industries.
Accurate Measurements in Sterile Applications
The TM311 provides accurate measurements in sterile applications. Developed for universal use in industries requiring the highest sanitary standards, such as food and beverage processing, pharmaceuticals, and biotechnology, this thermometer excels. Its high-grade stainless steel construction, coupled with certifications like 3-A, EHEDG, and FDA, guarantees compliance with stringent hygiene regulations. The sensor’s ability to maintain high accuracy even with short immersion lengths is crucial for effective process monitoring in these sensitive environments.
Fast Response Time for Optimal Control
Experience fast response time for optimal process control with the TM311. Featuring the innovative TipSens technology, this RTD (Pt100) sensor achieves response times as low as 1.5 seconds (t90). This rapid thermal sensing capability allows for precise and immediate adjustments to process parameters, crucial for maintaining product quality and preventing deviations in sensitive applications. The short immersion lengths do not compromise its accuracy, making it ideal for dynamic processes where quick feedback is essential.
High Accuracy Across Wide Ranges
The TM311 delivers high accuracy across a wide operational range. Operating from -50 °C to 200 °C (-58 °F to 392 °F), this compact temperature probe maintains Class A accuracy according to IEC 60751. This precision is vital for industries where even minor temperature fluctuations can impact product efficacy or safety, such as in pharmaceutical manufacturing or high-purity food processing. The sensor’s reliability ensures consistent performance, supporting stringent quality control measures.
Versatile Connections for Easy Integration
Benefit from versatile connections for easy system integration with the TM311. This probe is available with a multitude of process connections, including hygienic options like clamp connections (ISO2852), aseptic screwed joints (DIN 11864-1), and metallic sealing systems, alongside standard threaded and weld-in adapters. Coupled with a standard M12 connector offering IP69 protection, installation and commissioning are simplified, even in challenging or space-constrained environments, greatly reducing setup time and effort for plant operators.
