MAMAC Systems TE-205-A-3 Temperature Sensor

The MAMAC Systems TE-205-A-3 is a professional-grade space temperature sensor designed for high-precision monitoring in building automation systems (BAS). At its core, this unit utilizes a 1,000 Ohm Platinum RTD sensor with a 385 curve, providing superior stability and linear resistance output across a wide operating range of -40°F to 210°F. The standard enclosure is constructed from durable, flame-retardant white polystyrene and features a fully louvered design. These vents ensure maximum airflow across the sensing element for a fast thermal response while maintaining an aesthetically clean profile suitable for commercial offices, schools, and hospitals.

For contractors, the TE-205-A-3 simplifies installation with its universal standard space enclosure, which mounts easily to a standard 2" x 4" junction box or directly to the wall. This 1K platinum RTD eliminates the drift common in thermistor-based sensors, making it the preferred choice for long-term HVAC temperature control in critical environments. With an accuracy of ±0.1% at 0°C, it ensures reliable data for energy management systems and VAV controllers without requiring frequent field calibration.

Key Benefits

• High-accuracy 1,000 Ohm Platinum RTD element offers long-term stability and minimal drift.
• Louvered standard enclosure design optimizes air circulation for rapid detection of ambient changes.
• Broad operating temperature range of -40°C to 100°C (-40°F to 210°F) covers most commercial applications.
• Simple two-wire pigtail electrical termination reduces field wiring time for HVAC technicians.
• Compatible with most major BAS and DDC controllers that support 1K Ohm Platinum 385 curve inputs.

Common Questions

Can the TE-205-A-3 be used for outdoor air sensing?
No, this specific model features a vented standard enclosure designed for indoor space monitoring. For outdoor applications, a NEMA-rated weather-shielded enclosure should be used.

Does this sensor occupy a digital or analog input on a controller?
It provides a passive resistance output via its platinum RTD sensor, requiring one analog input configured for 1K Ohm Platinum (385 curve).

What is the best mounting height for accurate space sensing?
For optimal space temperature monitoring, install the unit approximately 5 feet above the finished floor in an area with natural air circulation, away from direct sunlight or supply air diffusers.
