MAMAC Systems TE-703-C-12-A-1 Temperature Sensor

The MAMAC Systems TE-703-C-12-A-1 is a commercial-grade immersion temperature sensor engineered for precise thermal monitoring in hydronic systems. This unit features a 10,000 Ohm NTC Thermistor (Type II), known for its high sensitivity and stability in HVAC control systems and building automation. The 4-inch 304 stainless steel probe ensures rapid thermal response while resisting corrosion in closed-loop applications. Designed for seamless integration, it includes a 1/8" NPT adapter for secure mounting and a NEMA 1 galvanized steel enclosure to protect internal connections from debris and mechanical damage. Whether you are managing chilled water loops or boiler feed lines, this sensor provides the accurate resistance-to-temperature curves required for BAS (Building Automation Systems) and DDC (Direct Digital Control) hardware. Its robust construction and standardized Type II thermistor curve make it a reliable drop-in replacement or new installation component for demanding industrial and commercial environments.

Key Benefits for Technicians:

• Standardized Resistance: The 10K Ohm Type II NTC thermistor ensures compatibility with major controllers like Johnson Controls and Honeywell.
• Industrial Durability: Equipped with a NEMA 1 enclosure and galvanized steel housing to withstand typical mechanical room conditions.
• Precision Accuracy: Low drift and high Interchangeability reduce the need for field calibration and system troubleshooting.
• Versatile Mounting: The 4-inch probe length and 1/8" NPT fitting facilitate easy installation in standard pipes and tanks.

Common Questions:

What is the difference between Type II and Type III 10K thermistors?
The Type II thermistor used in the TE-703-C-12-A-1 has a specific resistance-to-temperature curve that differs from Type III (CP curve). Always verify the controller’s required input curve before installation to ensure accurate temperature readings.

Can this sensor be used in high-vibration applications?
Yes, the stainless steel probe and NEMA 1 enclosure are designed to handle standard mechanical vibrations found in commercial pumping stations and boiler rooms.

Is a thermowell required for this immersion sensor?
While the probe is durable, using a thermowell is recommended for pressurized systems to allow for sensor replacement without draining the entire piping network.
