DIN KOS203TC Temperature Converter In-Head

The transmitter is an in head 4-20mA transmitter that connects to a standard thermocouple sensor and converts the sensor temperature to a 4-20mA signal.

An LED provides visual indication of sensor fault and programming mode. The transmitter is simply ranged and calibrated on the bench by using a single on-board push button switch, without the need for soldering links.

Digital technology ensures accurate and drift free linearisation to common curves, providing a level of performance not possible with earlier analogue types.
