MAMAC Systems TE-205-F-5 Temperature Sensor

The MAMAC Systems TE-205-F-5 is a professional-grade outside air temperature sensor designed for precise building automation systems and HVAC control integration. Engineered with a high-stability 1,000 Ohm Balco RTD sensor, this unit provides a linear resistance-to-temperature output with an accuracy rating of +/- 0.5°F at 70°F (21.1°C). The 4300 PPM/K temperature coefficient (T.C.R.) ensures repeatable monitoring for economizer control and ambient air sensing requirements.

Housed in a rugged NEMA 4 (IP65) die-cast aluminum enclosure, the TE-205-F-5 is built to withstand extreme climatological conditions without signal degradation. The 304 stainless steel probe is hermetically sealed to prevent moisture migration and building air leakage, which are common causes of sensor drift. With a 1/2-inch NPT threaded hub and a liquid-tight cord connector, technicians can achieve a secure, weather-sealed field installation on any flat surface or outdoor junction box.

• Precision RTD Element: 1,000 Ohm Balco sensor provides reliable BAS/DDC compatibility and fast thermal response.
• Environmental Protection: The NEMA 4 / IP65 rating ensures protection against high humidity, contamination, and thermal shock.
• Elimination of Accuracy Errors: Hermetically sealed design prevents building envelope air from skewing ambient temperature readings.
• Industrial Construction: Die-cast aluminum housing and stainless steel probe provide long-term stability in harsh mechanical environments.
• Versatile Installation: Standard 1/2" NPT hub allows for seamless integration with liquid-tight conduit or traditional fittings.

• Does this sensor require calibration? The 1,000 Ohm Balco element is factory-calibrated for high precision; however, verify the ohms-to-temperature curve against your controller's input settings during commissioning.
• How do I prevent erratic readings? Ensure the liquid-tight connector is properly seated to prevent moisture from reaching the terminals, as condensation is the leading cause of signal fluctuations.
• Where is the best location for mounting? Install on the North side of the building or in a shaded area to avoid solar gain interference with the outside air temperature reading.
