PT-1000 temperature transmitter
Model PT1000 temperature transmitter It is made by heat. The resistance and temperature transmitter circuit module is composed of a two-wire system (that is, a pair of wires is both a power supply power line and a signal transmission line), with a nonlinear correction circuit, which can measure various media in the range of -50 ~ 150 ° C in the industrial process. To convert the temperature signal into a linear temperature signal. 4 ~ 20mADC; Current output signal, send display, Adjust recording instrument or DCS The system carries out distributed control.
PT1000 temperature transmitter used in rail transit industry, can be used with moving coil instrument, digital display instrument, recording instrument, regulator, DCS system to form a variety of temperature measurement and control system.
