Handheld Terminal and TX60-RS232C Computer Interface for Setup and Automatic SelfCalibration Every 3 Sec on the TX62 and TX63

The TX62, TX63, TX64 programmable transmitters provide an isolated 4 to 20 mA signal linearized to temperature or process input. The TX62 & TX63 smart transmitters provide the same functions as the TX64 with the additional feature of smart communications. Smart communications lets one calibrate, reconfigure or check status right at the transmitter via the TX60-HH or from a remote location with the TX60-RS232. The TX60-HH is a battery operated handheld terminal that connects to the output of the transmitter anywhere along the pair of loop wires. The TX60-RS232 connects the same way and provides a 25-pin RS232 connection for use with a remote PC.

TX63

365

The TX63 extends “Smart” technology to signal conditioners. The same power that digital processing brought to “Smart” transmitters is available now for signal conditioning. The TX63 accepts a variety of inputs: volts, millivolts, milliamps, potentiometers, and resistance. The TX63 can linearize almost any input. Square, square root and logarithmic functions are easily selected. For more difficult linearization tasks, a 21-point custom linearization curve can be entered by the user.

TX64

325

The TX64 combines the best features of conventional analog transmitters with the advances of digital technology. The result is a programmable 2-wire temperature transmitter that sets new standards of performance. The TX64 is the ideal replacement for conventional temperature transmitters. The high performance, low initial cost and substantially reduced maintenance means a significant overall cost savings for your process. The TX64 is extremely easy to use and does not require a handheld terminal.
