Dataforth SCTP20 热电偶温度变送器

Thermocouples or RTDs. The input type, measurement range, and other features are software configurable. A PC, the DSCX-887 and DSCX-440 interface cables, and the DSCX-895 configuration software are required to configure the transmitter. Communication is serial RS-232C. User can choose an isolated or non-isolated model. The SCTP20 can interface to 12 industry standard thermocouple types: J,K,T,E,R,S,B,N,L,U,C, and D. Cold junction compensation is selectable as either internal or external. Three RTD types, Pt 100, Cu50*, and Ni 100, can be interfaced in a two, three or four wire connection. All inputs are linearized using up to 23 points of interpolation, and total errors are less than ±0.2%. Other configurable features include: zero point and input range adjustment, output response for open or short-circuit sensor or cable failure, normal or inverted output, ripple suppression for 50Hz or 60Hz, and output time response. The DSCX-895 configuration software allows query, print-out and saving of configuration settings, display of input measurement value, and display of interpolation table points. *Call factory for Cu RTD information.
