Overview

The SICK THTL temperature transmitter is a sanitary Pt100 sensor designed for integration into pipelines within the food, beverage, pharmaceutical, and biotechnology industries. It features a straight-through housing that inserts directly into pipes, with a probe immersed in the medium via an elastic sleeve. The unit offers high long-term stability, precision, and linearity compliant with IEC 60751 Class A standards. Available measurement ranges are –50 °C to +150 °C and –50 °C to +250 °C. The wetted parts consist of corrosion-resistant 316L/1.4435 stainless steel with Ra ≤ 0.8 µm. Electrical connections include 4-wire Pt100 or 2-wire 4–20 mA output via an M12 circular connector. The device provides IP67/IP69K protection and supports CIP/SIP processes.

Feature Summary

• Hygienic design with smooth process connection ends suitable for orbital welding and no dead spaces
• Sensor replacement without breaking process or electrical connections to minimize downtime and contamination risk
• Integrated transmitter allows computer programming of range, damping, error signals, and tags per NAMUR NE 043
• Robust construction with anti-corrosion stainless steel wetted parts ensuring short response times

Applications

• Temperature measurement in food and beverage processing pipelines
• Sanitary temperature monitoring in pharmaceutical production
• Biotechnology and cosmetic manufacturing fluid control
• Clean-in-place (CIP) and sterilize-in-place (SIP) system integration

Procurement Notes

Verify the specific model suffix against official SICK documentation to confirm the exact electrical interface (Pt100 vs. 4-20mA), measurement range, and connection type. Ensure the ordering code matches the required process connection geometry and material specifications for your pipeline integration. Cross-reference the IP rating requirements with your cleaning protocols to confirm compatibility with high-pressure spray washing.

Selection Notes

Select this component when sanitary hygiene standards and rapid maintenance access are critical. Choose based on the required temperature range and whether direct resistance measurement or a standardized analog signal is preferred. Confirm the M12 connector orientation and cable length needs. Ensure the Ra surface finish meets your industry's specific cleanliness validation criteria.

Part Context

This device belongs to the SICK THTL series of sanitary temperature transmitters. It is engineered specifically for hygienic applications where traditional sensors cannot be easily cleaned or maintained. The series emphasizes operational safety and system availability by allowing sensor changes without disturbing the process seal, addressing key challenges in regulated industries like food and pharma.

Replacement Considerations

Consult official SICK substitution guides for compatible upgrades. Verify that any alternative maintains the same sanitary housing dimensions, material certifications, and electrical interface to ensure seamless retrofitting without pipeline modification.
