These room temperature probes with real 2-wire transmitters are ideal for the temperature monitoring and control in office, works and living rooms. The 2-wire transmitter technology allows an easy integration of these probes within any climatic control plant. The temperature range is user configurable (minimal bandwidth 20°C). The room temperature probes are available either with 4-20 mA or a 0-10 VDC analog output. The outdoor temperature probes are available in different executions according to the protection indexes (IP65, IP67...) and to the built in sensing element. Standardly the measuring insert contains a Pt100-RTD conform to DIN EN 60751 (IEC 751) class B in 2-wires connection. Other executions with Pt1000, Ni1000, TK 5000, NTC 5kOhm, NTC 10kOhm or KTY are available. The extension to the evaluation electronic can be done either in 2-, 3- or 4-wires connection. As option an analog transmitter can be integrated in the housing.
