TMA Resistance Thermometer with Transmitter

Brand: KOBOLD Instruments, Inc.

The screw-in temperature sensors with integrated transmitter are used with the plug-on display model AUF as economical digital thermometers with Analog output (4 to 20 mA). The plug-on display is available with limit contact as an option.

The model TMA temperature sensors comprise a rugged sensor made of stainless steel with fixed G 1/2" or 1/2" NPT external thread. The bulbs have been designed for pressures up to 36 bar, depending on the process conditions.

A connector according to DIN 43 650 allows the transmitter to be easily connected electrically or retrofitted with the plug on display.

The temperature sensor is equipped with a stand-off for process temperatures >150° C.

A Pt 100 temperature sensor according to IEC 751, category B is fitted in the measuring insert as standard.
