Description
The Siemens Building Technology 536-767-25 is a precision immersion temperature sensor engineered for building automation and hydronic monitoring applications. Delivering a standard 4-20mA analog output signal, this sensor integrates seamlessly with building automation systems (BAS), DDC controllers, and energy management platforms that require accurate, real-time fluid temperature data.
Key Features
- 4-20mA industry-standard output signal for direct compatibility with BAS and DDC controllers
- Temperature sensing range: 30°F to 250°F (-1°C to 121°C)
- 2.5-inch probe length — ideal for standard pipe and duct immersion applications
- Thermowell included for easy installation and sensor replacement without draining the system
- Lead-wire connection type for flexible field wiring
- No display — clean, compact design suited for panel or concealed installations
Application
The 536-767-25 is well-suited for monitoring supply and return water temperatures in hydronic heating and cooling systems, chilled water loops, hot water systems, and other HVAC piping applications. The included thermowell allows the sensor to be installed and serviced without interrupting system flow, reducing downtime and maintenance costs.
