DPS3100D Smart Pressure Transmitter

For Monitoring Hydronic HVAC Systems

Taco DPS sensors monitor the differential pressure in a hydronic HVAC system. As the system operates and sees an increase or decrease in demand, these sensors relay the system pressure changes back to the building management system or VFD to modulate pump speed. Taco offers two models: the DPS629 Differential Pressure Transmitter, designed to meet NEMA 4X (IP66) construction, and the DPS3100D Smart Pressure Transmitter, with a 100:1 turn downrange that allows the smart transmitter to be configured to fit any application.

DPS3100D

The Taco DPS3100D Smart Pressure Transmitter is a microprocessor-based high-performance transmitter that has flexible pressure calibration, push-button configuration and programmable using HART® Communication. The DPS3100D is capable of being configured for differential pressure or level applications with the zero and span buttons. A field calibrator is not required for configuration. The transmitter software compensates for thermal effects, improving performance. EEPROM stores configuration settings and stores sensor correction coefficients in the event of shutdowns or power loss. The DPS3100D is FM approved for use in hazardous (classified) locations. The 100:1 range-ability allows the smart transmitter to be configured to fit any application.
