Description
Freezer PT100 RTD Temperature Probe (Model APES-6×50) is designed for accurate temperature measurement in commercial freezers, cold rooms, refrigerated warehouses, blast freezers, and cold-chain logistics systems. Its compact SS316 stainless steel probe combined with a Teflon/Teflon insulated cable provides reliable performance in environments where repeated temperature cycling between sub-zero storage conditions and warmer ambient temperatures can place stress on conventional sensor cables.
The sensor incorporates a Simplex PT100 3-wire sensing element with Class B accuracy, helping reduce lead wire resistance effects while delivering stable temperature measurements for refrigeration control, monitoring, and data logging systems. The 50 mm long, 6 mm diameter SS316 probe is suitable for installation in confined locations, while the 3-meter cable allows convenient connection to external controllers, PLCs, data loggers, or building management systems.
Designed for demanding refrigeration environments, the Teflon insulated cable maintains flexibility across repeated cooling and warming cycles, making the sensor suitable for continuous monitoring in food storage, pharmaceutical refrigeration, laboratory freezers, and other temperature-controlled facilities.
Key Features
-
Sub-Zero Teflon Cable Flexibility (TF/TF) High-grade PTFE cable insulation remains completely flexible without cracking or hardening during continuous sub-zero exposure and defrost heat cycles.
-
Low-Temperature Rating Down to -50°C Engineered specifically for reliable operation in deep-freeze environments, commercial cold rooms, and cryogenic storage.
-
Compact 6mm x 50mm SS316 Sheath Space-saving stainless steel housing offers excellent corrosion resistance against moisture condensation and wash-down sanitizers.
-
3-Wire Lead Compensation 3-wire RTD circuit automatically cancels out line resistance across the 3-meter cable run, ensuring true temperature accuracy at the controller.
-
Extended 3-Meter Reach Generous cable length easily penetrates insulated freezer paneling to reach externally mounted digital indicators or logging stations.
-
Ideal for Cold-Chain Compliance Monitoring Provides drift-free performance critical for HACCP, FDA, and pharmaceutical cold-storage compliance logging.
