MAMAC Systems TE-703-C-5-A-2 Sensor

The MAMAC Systems TE-703-C-5-A-2 is a professional-grade immersion temperature sensor specifically engineered for high-accuracy monitoring in chilled water, hot water, and low-pressure steam loops. This model features a high-precision 1,000 Ohm Balco RTD sensor, delivering a positive temperature coefficient that ensures stable and repeatable resistance outputs across a wide operating range of -40°F to 210°F. The 4-inch 304 stainless steel probe is hermetically sealed to prevent moisture migration, reaching deep into the thermal stream for rapid response times without risk of sensor drift.

Designed for easy field integration, this unit includes a 1/4" NPT adapter for secure mounting into standard thermowells. The NEMA 1 galvanized steel enclosure provides a rugged housing for internal wiring, featuring a keyed 18-gauge cover that swings open for quick access during commissioning. For contractors managing HVAC building automation systems, the TE-703-C-5-A-2 offers the reliability needed for commercial boiler controls and industrial cooling systems where precision is mandatory. Its robust construction minimizes maintenance requirements in unconditioned mechanical rooms, ensuring long-term performance in demanding environments.

• Precision Sensing: The 1,000 Ohm Balco RTD provides industry-standard accuracy with excellent linearity for BAS temperature monitoring.
• Rugged Durability: Features a 304 stainless steel probe and a heavy-duty NEMA 1 enclosure to withstand mechanical shock and vibration.
• Versatile Compatibility: Standard 1/4" NPT adapter and resistance output make it compatible with most major DDC controllers and HVAC sensors.
• Streamlined Installation: Keyed enclosure cover allows for 6-foot plenum-rated lead wire termination without removing the mounting screws.

What is the resistance curve for this Balco sensor?
The MAMAC TE-703-C-5-A-2 utilizes a 1k Ohm Balco element with a TCR of 4,300 PPM/K, reaching 1,000 Ohms at 70°F (21.1°C). Always verify the resistance-to-temperature table in the technical specifications for your specific DDC controller calibration.

Can this sensor be installed directly into a pipe without a thermowell?
While the 304 SS probe is rugged, we recommend using a compatible thermowell for immersion applications to allow for sensor replacement without draining the system and to provide additional protection against high-velocity flow.

Is the enclosure suitable for outdoor use?
This specific model features a NEMA 1 galvanized steel enclosure, which is rated for indoor, conditioned, or protected environments. For outdoor or high-moisture areas, a NEMA 4/IP-65 rated enclosure would be required.
