Sitrans TR300

 Sitrans TR300

Order No: 7NG3033-…..

SITRANS TR300 with HART- protocol is designed to support all commons, thermocouples, resistance and Millivolt sensors. Setup is quick and easy with SIMATIC PDM or handheld communicator. Unique user-friendly details are implemented: Without opening the 4-20mA loop the output current can be read out directly with a multimeter. A red/green LED shows the technician the status at a glance.

Benefits:

• Measures temperature with a linear output signal
• High accuracy across entire ambient temperature range
• Reduces plant noise
• Alarm signal for sensor break or short-circuit according NAMUR 43
• Electromagnetic compatibility (EMC) according DIN EN 61326 and NE21
• Galvanic insulation for accuracy and safety in thermocouple applications
• Single- or dual-point trim
• Custom characteristic curve for application of non-standard sensors
• Difference- and average- measurement
• Extensive diagnosis: e.g. drag indicator and time meter
• Set of output current for simulation
• Explosion protected versions for Europe
• Rugged design, potted electronics

Application

SITRANS TR300 transmitters can be used in all industrial sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets. The following sensors/signal sources can be connected over their universal input module:

• Resistance thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources

The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic, superimposed by the digital HART signal.

Transmitters of the “intrinsically safe” type of protection can be installed within potentially explosive atmospheres. The devices comply with the Directive 94/9/EC (ATEX).
