MAMAC Systems TE-703-C-17-A-3 Temperature Sensor

The MAMAC Systems TE-703-C-17-A-3 is a precision-engineered immersion temperature sensor designed for accurate fluid temperature monitoring in chilled water, hot water, and condenser loops. This model features a 20,000 Ohm NTC thermistor, ensuring high-resolution signal output and long-term stability with minimal drift. The 4-inch 304 stainless steel probe is built to withstand demanding hydronic environments, providing rapid thermal response times. Housed in a NEMA 1 galvanized steel enclosure, the unit includes a 1/2" NPT brass adapter for secure threading into thermowells. For contractors and building automation specialists, this HVAC temperature probe offers seamless integration with controllers that support 20K Ohm curves. The rugged construction and simplified wiring interface make it a reliable choice for BAS/DDC system upgrades and industrial process controls where accuracy and durability are non-negotiable requirements.

• High-Accuracy Sensing: The 20K Ohm NTC thermistor provides precise resistance-to-temperature conversion for tight control loops.
• Durable Probe Construction: A 4-inch stainless steel immersion probe resists corrosion and maintains integrity in high-pressure piping.
• Standardized Fitment: Features a 1/2" NPT adapter for universal compatibility with standard thermowell fittings.
• Robust Protection: The NEMA 1 galvanized steel housing protects terminal connections from mechanical damage and dust.
• Wide Application Range: Ideal for monitoring liquid temperatures in boilers, chillers, and HVAC heat exchangers.

What is the resistance curve for the MAMAC TE-703-C-17-A-3?
This sensor utilizes a 20,000 Ohm NTC thermistor curve, which is a standard specification for many compatible building automation controllers.

Can this sensor be used without a thermowell?
While the 1/2" NPT adapter allows for direct mounting, it is standard trade practice to use a thermowell to protect the probe and allow for replacement without draining the system.

Is the probe length sufficient for large-diameter pipes?
The 4-inch immersion probe length is optimized for medium-diameter piping, ensuring the sensing element is positioned within the active fluid flow for accurate temperature monitoring.
