Description
MAMAC Systems TE-703-D-12-A-2 Immersion Temperature Sensor Overview
The MAMAC Systems TE-703-D-12-A-2 is a precision immersion temperature sensor engineered for reliable liquid temperature measurement in commercial and industrial HVAC and building automation applications. Designed to mount directly into pipes and vessels via a 1/4″ NPT threaded adapter, this sensor delivers accurate, repeatable readings that building automation and control systems depend on.
10,000 Ohm NTC Thermistor (Type II) Sensing Element
At the heart of this sensor is a 10,000 Ohm NTC (Negative Temperature Coefficient) Thermistor, Type II — a widely supported sensing curve compatible with a broad range of BAS controllers, DDC systems, and building automation platforms. The NTC thermistor provides a highly sensitive response to temperature changes, making it ideal for hydronic heating and cooling systems, chilled water loops, condenser water circuits, and process piping.
Key Features
- Sensor Type: 10,000 Ohm NTC Thermistor, Type II
- Probe Length: 4 inches — suitable for standard pipe immersion depth requirements
- Pipe Connection: 1/4″ NPT threaded adapter for secure, leak-free installation
- Enclosure: NEMA 4 rated painted steel housing — protects against dust, splashing water, and washdown conditions
- Compatible with a wide range of DDC and BAS controllers supporting 10K Type II thermistor inputs
- Rugged construction suitable for commercial and light industrial environments
NEMA 4 Painted Steel Enclosure
The NEMA 4 rated painted steel enclosure provides robust protection for the sensor’s internal wiring and connections. NEMA 4 enclosures are designed to protect against ingress of solid foreign objects, windblown dust, rain, sleet, snow, and splashing water — making this sensor well-suited for mechanical rooms, boiler plants, and other demanding installation environments.
Installation & Compatibility
The 1/4″ NPT adapter allows for straightforward installation into standard pipe taps or thermowell fittings. The 4″ probe length ensures adequate immersion depth for accurate fluid temperature sensing in typical pipe diameters. This sensor integrates seamlessly with MAMAC Systems controllers as well as third-party DDC platforms that accept a 10,000 Ohm NTC Type II thermistor input signal.
Typical Applications
- Chilled water supply and return temperature sensing
- Hot water heating system monitoring
- Condenser water loop temperature measurement
- Boiler supply and return sensing
- Process fluid temperature monitoring
