SEM104PT100

SEM104 is a 4 to 20mA temperature sensor transmitter that can be housed in a head mount DIN standard enclosure. The SEM104P is for Pt100 inputs and is field range able if necessary, using links on the printed circuit board and the use of on-board SPAN and ZERO potentiometers. The same two wires that power the transmitter also carry the transmission current such that only two connections are required. SEM104P uses high precision and thermally stable components throughout, giving it a very stable performance over its operating range.
