  [Transmitters/Controllers] HART¢ç Smart Isolated 2-Wire Transmitter
  ±Û¾´ÀÌ : ´ÙÀÏIBC     ³¯Â¥ : 09-03-21 22:57     Á¶È¸ : 14266    

Conax Model: HST

 
The Conax Model HST HART¢ç Smart Isolated 2-Wire Transmitter features universal input capability in 3 variations to accept most of today¡¯s process parameters: Thermocouples, RTDs, DcmV, Potentiometers, Resistance Sensors, DcmA, DCV, AC Amps, Frequency and Pulse.
Model HST is fully software driven and all input parameters are programmable. An external hand-held programmer, an integral transmitter mounted programmer, or HART protocol hand-held enables on site calibration, and indication of process parameters. Other features of the Model HST include high precision linearization for thermocouple and RTD sensor inputs, inverse output capability, variable input signal damping, sensor breakdown indication, full display scaling capability, auto-zero input, and more.
Heavy duty metal case construction and carefully designed input and output circuitry ensures a high degree of protection from adverse environmental conditions to maximize RFI/EMI immunity.
Optional features include LCD display with integral programmer, hand-held programmer, and explosion-proof: enclosure:
  • CL I, GRPS B, C, D
  • CL II, GRPS E, F, & G
  • CL III Type 4X
