The SITRANS TH300 with HART protocol is a universal industrial temperature transmitter designed to support all common thermocouples, resistance thermometers, and millivolt sensors. This molded plastic transmitter features quick setup via SIMATIC PDM or handheld communicator and includes advanced diagnostic capabilities.

• Measures temperature with linear 4-20 mA output signal
• High accuracy across entire ambient temperature range
• Reduces plant noise interference
• Alarm signal for sensor break or short-circuit (NAMUR 43)
• Electromagnetic compatibility (EMC) according to DIN EN 61326 and NE21
• Internal reference junction eliminates need for expensive compensation cables
• Galvanic insulation for accuracy and safety in thermocouple applications
• Single- or dual-point trim capability
• Custom characteristic curves for non-standard sensors
• Difference- and average measurement functions
• Extensive diagnostics including drag indicator and time meter
• Output current simulation for testing
• Explosion-protected variants for US, Canada, and Europe
• Rugged design with fully potted electronics

SITRANS TH300 transmitters are suitable for all industrial applications. Their compact design allows installation in connection heads of type B (DIN 43729) or larger. The universal input stage supports resistance thermometers, thermocouples, resistance-type transmitters/potentiometers, and DC voltage sources.

Springs and screws for securing the transmitter are included. The device can be secured either in the base of the connection head or in the raised cover of the connection head.
