ROSEMOUNT TRANSMITTER

Product Introduction

The Rosemount 644 temperature transmitter is designed for use in control applications where the loss of the temperature points may be detrimental. These highly accurate Rosemount 644 temperature transmitters are available in a variety of mounting styles, field housings, and communication protocols to meet your demanding installation requirements.

Each Rosemount 644 temperature transmitter is a 2-wire design providing either a 4-20 mA/HART or a completely digital FOUNDATION fieldbus ouput. Each unit can be configured for a variety of sensor inputs: RTD, themocouple, millivolt, or ohm. The advanced Rosemount 644 temperature transmitter powers PlantWeb ® by communicating important temperature diagnostics and PlantWeb alerts to ensure process health and enable economical single-sensor architecture.Entering the temperature-resistance profile specific to the RTD sensor into the Rosemount 644 temperature transmitter results in transmitter-sensor matching. This eliminates the sensor interchangeability error, which can improve accuracy by up to 75%. The integral LCD display provides local indication of temperature measurement and diagnostics for immediate and accurate verification or process conditions.

Meeting the NAMUR NE 21 recommendations, the Rosemount 644 temperature transmitter ensures top transmitter performance in harsh EMC environments. In addition, the Rosemount 644 HART transmitter meets NAMUR NE 43 and NE 89 recommendations.

The Rosemount 644 temperature transmitter offers great mounting flexibility. The DIN A style head mount transmitters fits a variety of housings for remote transmitter mounting and can be integral or remote mounted to a sensor. The compact rail mount style is great for DIN rail mounting in the tight spaces of a crowded control room.

• The high temperature melt pressure transducer is an electronic device that transforms a physical variable (pressure) into an electrical signal (current or voltage or in Can Open, IO-LINK, HART), acquired by the various control, measurement and regulation devices. 
• GEFRAN melt sensors are pressure/temperature transducers and transmitters designed for use in environments that reach very high temperatures, capable of detecting average pressure up to 538 °C. 
• Based on two main construction technologies (with extensometric filling fluid technology or totally fluid free with silicon piezoresistive technology), Gefran high temperature pressure sensors are available in 4 different designs: rigid stem, flexible sheath, flexible with thermocouple and exposed capillary. 
• Their high immunity to electromagnetic interference allows these sensors to be installed in any operating environment. 
• The devices guarantee vast coverage of detectable pressures, from the minimum range with a scale of 0-17 bar up to a range of 0-3000 bar. 
• The available output signals are mV/V, 4-20mA, 0-10V, Gauge type, CANOpen, and IO-LINK. 
• Atex and PLd and SIL 2 versions complete the range for the various architectures and applications present on the plastics converting machinery market. 
• The Melt sensor is ideal for applications in the polymer production and processing industry.

The remote mount sensor is rated IP68 for submergence to a depth of 33 ft (10 m) for a period of 48 hours. IP68 rating requires that the transmitter must be remote mount. Installer must use IP68 approved cable glands, conduit connections, and/or conduit plugs.Hot Tags: rosemount 8705 flanged magnetic flow meter sensors, manufacturers, suppliers, wholesale, agent, good price, sale
