Thanks to its compact design, it allows use in the low-cost connection head Form B, even in the flat-cover version where it is installed in place of the terminal block. It also has a host of userfriendly and safe features. Thanks to clear functional positioning, all users will find the device that ideally supports their requirements.

We offer a range of Head Transmitters Products.

This range includes,

  • SITRANS TH100
  • SITRANS TH200
  • SITRANS TH300
  • SITRANS TH400

  • SITRANS TH100

    SITRANS TH100 is rigid designed for economic use. For example with saving of the galvanic insulation, which is not need for PT100. Therefore the TH100 offers economic plant operation and reliable measurements. It is an ideal substitute for over aged analogue PT100 transmitters. Setup is quick and easy with the transmitter-modem and SIPROM T. This configuration tool can be downloaded for free.

    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
  • Explosion protected executions for US, Canada and Europe
  • Slim design, ideal for upgrade of installed PT100 probes with a 4-..20mA signal
  • Rugged design, fully potted electronic


  • Details
  • Input - Pt 100 resistance
  • Output - 4 to 20 mA

  • SITRANS TH200

    SITRANS TH200 is designed to support all common RTDs, thermocouples, resistance and millivolt-sensors. Setup is quick and easy with the transmitter-modem and SIPROM T software. This configuration tool can be downloaded free. Unique user-friendly details are implemented: Without opening the 4-..20mA loop, the output current can read 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
  • Electro magnetic compatibility (EMC) according DIN EN 61326 and NE21
  • Saves expensive compensation cables with the 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
  • Explosion protected executions for US, Canada and Europe
  • Rugged design, fully potted electronics


  • Details
  • Input - Resistance thermometers, Thermocouples, Resistance-type sensors, DC sources
  • Output - 4 to 20 mA

  • SITRANS TH300

    SITRANS TH300 with HART- protocol is designed to support all common 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 read out directly with a multimeter. A red/green LED shows the technician the status at a glance.
