Series temperature transmitter module HD-TT is the thermal resistance type (Pt100, Pt1000, Cu50, Cu100) temperature sensor matched 4 ~ 20mA, two-wire DC output module. Can form a complete set of integrated temperature transmitter, also can be installed separately. The module adopts imported devices, SMT assembly, stable and reliable performance, small volume, convenient installation.
HD-TT series temperature transmitter moduleDetails
The module of the security proof, has powerful protection function, fully open in the sensor (not to), the output current ≤ 3.6mA; when the sensor line open circuit, module for the protection of output, the maximum current of not more than 25 ± 2mA.
Main technical parameters:
2, the calibration method: (1) with resistance box or other signal source generator instead of thermal resistance in Figure 1 wiring. (2) according to the indexing table. The corresponding resistance box to the lower limit of the range of the resistance, fine tune the zero potentiometer, the current meter reading is 4mA. (3) according to the table, the corresponding resistance box to the upper range of the resistance, fine tune the full belly potentiometer, the current meter reading is 20mA. (4) completed (if necessary, repeat steps (2) (3), so as to meet the requirements).
