Application

SITRANS TH300 transmitters can be used in all industrial sectors. Its compact size means that it can be installed in connection heads of type B or larger. The following sensors/signal sources can be connected over their universal input module:

• 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 to NAMUR 43
• Electro magnetic compatibility (EMC) according to DIN EN 61326 and NE21
• Save expensive compensation cables with internal reference junction
• 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 variants for US, Canada and Europe
• Rugged design, fully potted electronics

• Resistance thermometer (2-wire, 3-wire, 4-wire connection)
• Thermocouples
• Linear resistance, potentiometer and DC voltage sources
• With HART communications interface:

• 2 resistance thermometers (2-wire, 3-wire, 4-wire connection)
• 2 thermocouples
• 2 linear resistors, potentiometer and DC voltage sources
• The output signal is a load-independent direct current from 4 to 20 mA in accordance with the input characteristic, superimposed by the digital HART signal.

• High availability during measurement by hot backup function (SITRANS TH420)
• High reliability and long-term stability – sensor trim (Callendar-van-Dusen) and sensor drift detection (SITRANS TH420 only) for high accuracy and accelerated calibration time 
• Avoidance of production stop because of measurement failures
• Best cost-benefit ratio for facility management
• Cost reduction through anticipatory maintenance
• Withstanding safety-critical environments - Extended temperature range up to -50°C and SIL2/3 approvals

• Transmitter in 2-wire system with M12 device plug for mounting on compact thermometer.
• Solution for easy and space-saving temperature measurements in a variety of industries.
• Programmable; as a result, the sensor connection, measuring range and much more are programmable.
