The CYTX231 temperature transmitters send linearized data to a remote location for a data acquisition system or a recorder using a 4-20 or 0-20mA signal. Standard Curve #10 chart shown in the T section is in memory for the silicon diode sensor and excitation of 10µA is provided. The CYTX231P operates like the CYTX231SD but uses a 100Ohm platinum RTD sensor. Excitation provided is 500µA and a DIN 437600 standard curve is provided in memory.
