Rosemount 333 HART® Tri-Loop™
The Rosemount 333 HART Tri-Loop enables the conversion of a digital multivariable HART signal into three independent 4-20 mA analog process variables. Apply in control or monitoring applications to obtain up to three additional analog outputs without additional process penetrations.
- Convert a digital HART Signal into three additional analog signals
- Easy to configure and install
- Accessory product for multivariable instruments
- Available as either High-alarm or Low-alarm device
|
- Converts a multivariable digital HART signal into three independent 4-20 mA analog process variables
- When used with a Rosemount 3051SMV or 3095MV, the 333 HART Tri-Loop allows possible outputs of Differential, Absolute, or Gage Pressure, Process Temperature, and Mass Flow.
- When used with the Rosemount 3051S with Advanced Diagnostics, possible outputs include Pressure, Sensor Module Temperature, Scaled Variable, Standard Deviation, and Mean.
- When used with the Rosemount 3144P, possible outputs include Sensor 1, Sensor 2, Differential and Transmitter Terminal Temperature.
- Available as either High-alarm or Low-alarm device
- Installation is quick and easy with three DIN rail mount options and electrically isolated analog output channels for flexible grounding.
- Easy to configure and maintain using AMS Device Manager or 375 Field Communicator
