Mighty Module Model SF1302
RTD Input Slim Profile Two Wire Transmitter
The SF1302 is a low-cost, reliable, RTD input two-wire transmitter designed with the OEM in mind. These transmitters are housed in a low profile, 50 mm diameter extruded aluminum case. This thin design allows two transmitters to be stacked in one standard connection head for use with dual RTD sensors.
The SF1302 provides a DC output current (4/20 mA) proportional to a two-wire RTD input. Filtering and conditioning to reduce susceptibility to transients and noisy operations provides accurate, trouble-free operation. Linearization is provided for platinum RTDs.
The SF1302 utilizes a single constant current source to excite the RTD. The output ZERO and SPAN controls are located on the top of the case. Zero is adjustable ± 20% and span ± 15%. Terminations are made to screw terminal connectors on the top of the case. A center hole provides clearance for 1/4 inch diameter and smaller sensors.
Remote temperature data acquisition.
The SF1302 can be mounted in a connection head (TSH-A6L), explosion-proof housing (XJAY), or on a flat surface using the two 4.5 mm diameter mounting holes provided. Standard 33 mm hole center spacing allows for mounting in most connection heads. The 5.08 mm center hole allows clearance for input wiring or for a 3/16 diameter temperature probe. An optional DIN-Rail mounting kit is available (DMP2000). Two transmitters can also be stacked in the DIN rail if space is limited.
