Description
Please check out Newest Released 2-wire Transmitters with Standard, FM & Hart Models Available TXUN Series for more advanced features and excellent usability.TX250 Series
Thermocouple Input
The TX250 Series are non-isolated two-wire transmitter which convert the T/C thermoelectric voltage into a standardized load-independent, 4 to 20 mA process current.
The TX250 Series are housed in metal enclosures and fit into NB1 connection heads. The transmitter’s enclosure provides excellent RFI immunity.
The transmitter calibration is set by six dip-switches located behind the top cover. There are three basic models which cover the various T/C types. TX251 is for T/C types K, T and J TX252 is for type E and TX253 is for type R and S.
Dip-switch arrays select the T/C type, and set the "Zero" coarse level and the "Span" coarse range.
Zero and Span trimmers provide the fine tuning calibration.
TX254 RTD Input
The TX254 is a non-isolated two-wire transmitter which converts the measuring signal of a 3 wire 100 ohm Pt RTD into a standardized load-independent, 4 to 20 mA current which is linearly proportional to the measured temperature.
The TX254 transmitter is provided with excellent lead resistance compensation and Pt-100 linearization conforming to BS1904 and DIN 43760 characteristics (a = 0.00385). The transmitter calibration is set by six dip-switches located behind the top cover.
Three dip-switches set the lower measured coarse temperature and the other three dip-switches set the measured coarse temperature span.
Zero and Span trimmers provide the fine tuning calibration.
