The multi-point temperature measurement instrument takes the highest measured temperature in measuring loops as its output signal ,Which is displayed by the built-in LED. With buttons on panel, temperature at any measuring point can be shown directly, The corresponding indicator light above is on at the same time . Hint signal for sensor fault can also be sent out in the form of high alarm or low alarm.
·multi-channel input,single output
·4 to 20 mA analog output
·Only 8 V voltage drop within whole loop circuit
·Galvanic isolation from input to output
·The highest temperature for output displaying
·Fault signal on sensor break circuit
·High accuracy in total ambient temperature range
·Ex-Certification
·IP66(aluminum alloy casing)
·Digital display (LED)
·Anti-RFI- Certification( especially for intercom)
·MS151 Series multi-channel temperature monitor is mainly used in the applications of multi-point temperature measurement or alarm warning system. By adopting SMT technology, it offers excellent accuracy, reliability and anti-disturbance .
·Input type : Pt100, Cu50(TC if specially required)
·Measuring Points : 4, 6 points
·Temperature at any measuring point can be displayed by operating the keys on panel,The corresponding indicator light above the key is on at the same time .
·Hint signal for sensor fault can be sent out in the form of high alarm or low alarm.
