DW-TS transmitter is a 2-wire in-head temperature transmitter, microprocessor based designed for the flexibility of accepting mV, Pt100 and a variety of thermocouples as the input sensor. The delivers a scalable linear 4-20mA output signal proportional to the sensor temperature. User-friendly configuration software is provided for parameter set up, including sensor type, temperature range, filter, etc.
 
The Transmitter is mounted on the head of the temperature sensor and accepts either a three-wire RTD Pt-100 sensor or a Thermocouple sensor and converts it into a linear current loop signal of 4 to 20mA DC, capable of driving a load of up to 600 Ohms. The instrument operates in two-wire configuration.
