The SEM104P is for Pt100 inputs and is field rangeable if necessary, using links on the printed circuit board and the use of on-board SPAN and ZERO potentiometers. A wide selection of compatible probe assemblies are available with various immersion lengths and process connections `.` The same two wires that power the transmitter also carry the transmission current such that only two connections are required. This reduces installation and wiring costs whilst the nature of current transmission provides superb noise immunity and ensures that line impedances, thermoelectric effects etc. do not introduce errors. ## **FEATURE HIGHLIGHTS** ## **LOOP POWERED** The instrument is powered by the loop current; no additional power supply is required. ## **ANALOGUE PERFORMANCE** The SEM104P uses a proven and reliable analogue design on the input and output sections of its circuits. This leads to a very fast and smooth response time as there is no analogue-to-digital and digital-to-analogue conversions to be carried out during input monitoring through to retransmission of the signal. As no microcontrollers or digital ICs are used on the SEM104P, it makes it suitable for applications where digital components are to be avoided. The SEM104P uses resistor pots to allow the user to “trim” the 4 mA and 20 mA range points for maximum accuracy. ## **HIGH STABILITY** The SEM104P uses high precision and thermally stable components throughout, giving it very stable performance over its operating range.
