商品説明

The TX33 model has been discontinued. Please see the TX92G Series as a possible alternative or contact our Temperature Engineering Department.

The TX33 is an analog, nonisolated, 2-wire head-mounted temperature transmitter that converts the RTD input into a proportional, linear, and highly accurate 4 to 20 mA output current in a variety applications such as process control, automation system, and energy source management. The TX33 performes by means of a 6 dip-switch array for the coarse range setting, and two multi-turn potentiometers (Zero and Span) which are used for the final finetuning. The TX33 is housed in a metal enclosure with plastic top cover, fitting into DIN B connection heads providing excellent RFI immunity. The TX33 accepts low level signal from RTD, filtered, amplified, and converter to process current to reduce susceptibility transients and noise operations and allow the same two wires to carry the transmitter power and output current signal simultaneously.
