ATEX Version available
The SEM110 is an analogue temperature transmitter which can offer solutions where response time, high accuracy and stability is required. Offered to suit both RTD and Thermocouple temperature probes, the SEM110 can also be specified with ATEX approval. Temperature ranges need to be specified at the time of order.
The SEM110P accepts a Pt100 platinum resistance temperature sensor to BS1 904 or DIN 43760 standards or a thermocouple K, T, J, R or S and converts the sensor temperature to a current varying between 4 and 20 mA. Version are also available for slide wired (W), variable resistor (Z) or temperature deferential (D). The same two wires that power the transmitter also carry the transmission current such that only two connections are required. This drastically reduces installation and wiring costs whilst the nature of current transmission provides superb nose immunity and ensures that line impedance's, thermoelectric effects etc. do not introduce errors.
Transmitters are factory calibrated to the desired range within the accuracy stated, however, SPAN and ZERO potentiometers are available for periodic recalibration or for 'tweaking' out sensor errors when used with two wire or low grade detectors.
