Model TT111 RTD Temperature Transmitter
Brand: Tel-Tru Manufacturing Co.Factory calibrated for fixed range, the TT111 provide a 4-20 mA output linearized to temperature for Pt100. The wide temperature range makes the TT111 an excellent choice for temperature signal transmission.
Precision 20-turn potentiometers allow fine adjustment of ZERO and SPAN.
TT111 transmitters are high quality, very accurate, completely linearized and fit into industry standard connection heads.
