[pdf] The fixed distance between the two support points of the temperature-sensing cable should be within the range of 0. What each symbol means? Recommended mounting position Unsuitable mounting position Additional influencing factor that need to be taken into consideration For correct placement of. A temperature transmitter is commonly used to convert the output signal from temperature sensors like RTDs (Resistance Temperature Detectors) or thermocouples into a standard 4–20 mA current signal that can be read by a PLC or control system. The 900 series is an analogue heat sensing cable containing insulators of which resistance varies proportionally to changes in temperature. Analogue cable is installed in conjunction with an end-of-line (EOL) device for continuity monitoring and a modulator providing selectable alarm thresholds.
