Thermocouple Input Two Wire Transmitter Model TW304
Features
Description The TW304 is a low cost, reliable, thermocouple input, 2-wire transmitter for field or panel mounting in various industrial housings and enclosures. It provides a DC output current proportional to any thermocouple input signal. Cold junction compensation, low-drift chopper-stabilized amplifiers and filtering and conditioning to reduce susceptibility to transients and noisy operations, provide accurate, trouble free operation. Optional coating of the electronic components makes the TW304 extremely reliable and resistant to the corrosion, moisture and fungus associated with many industrial environments. The output ZERO and SPAN controls are accessible through the top of the case. Terminations are made to screw terminal connectors on the top of the case. Cold junction compensation is provided by a solid state temperature sensor embedded in the thermocouple terminal strip. Upscale burnout protection is provided as standard. In the event the thermocouple opens, the transmitter output will go offscale high. Typical Applications Remote temperature data acquisition. Mounting The TW304 can be mounted in a connection head (TSH-A6L) or on a flat surface using the two 5/32 inch holes provided. The 17/64 inch center hole allows clearance for a 1/4 inch diameter temperature probe. Specifications
