BASI´s temperature transmitter BTT783 is part of a revolutionary new project for the smallest (in-head) and cheapest multi-input programmable transmitter. It has a universal input accepting Pt100 RTD and 8 thermocouples and a voltage or current 2- or 3-wire output linearly proportional to the measured temperature. This model allows on-site selection of sensor type, input range and conversion direction as well as sensor failure reaction and no user calibration is necessary to be provided. BTT783 is available in a case for mounting inside sensor protection head type “B”, in a watertight box with high protection class, and in a case for mounting on DIN rail. The RS232 serial interface allows fast and easy configuration. Thanks to the combination of performance, reliability, simplicity, flexibility, and low price, the BTT783 transmitter is easy-to-use and very widely applicable.
