The temperature head transmitter Transcont KTM<\/strong> , for connection to a Pt100<\/a> resistance thermometer is a temperature signal converter for measuring, converting and monitoring temperatures in the range from -100 \u00b0 C to + 600 \u00b0 C with a measuring range between 20 Kelvin and 700 Kelvin.
\nThanks to the PNP switching output integrated in the 2-wire version (4 … 20 mA), separate evaluation devices can be dispensed with in many cases.<\/p>\n

Funktion<\/u><\/p>\n

The temperature head transmitter Transcont KTM<\/strong> can be installed in a connection head (form B) or in a field housing.<\/p>\n

A constant current is impressed from an integrated current source through a 2- or 3-wire Pt100<\/a> resistor built into the sensor. This current causes a voltage drop across the Pt100<\/a>, which increases or decreases depending on the level of the medium temperature to be measured.
\nThe resistance-proportional voltage signal generated on the Pt100<\/a> is recorded by the transmitter, linearized and converted into a direct current signal of 4 … 20mA or a direct voltage signal of 0 … 10V.<\/p>\n

The voltage signal of the Pt100<\/a> is monitored and if the sensor breaks, failure information is provided via the 4 … 20 mA or 0 … 10V output signal. In this case, the output signal rises to 21.7 mA or 10.85 V. In the event of a sensor short-circuit, the signal drops to 3.55 mA or 0 V.
\nWith the temperature head transmitter in 2-wire technology with 4 … 20 mA, a freely adjustable, overload and short-circuit-proof PNP switching output using the open-circuit principle is optionally integrated.<\/p>\n","protected":false},"excerpt":{"rendered":"
