TX100 pH/ mV Loop Powered Transmitter

TX100 pH/ mV Loop Powered Transmitter

The TX100 pH/mV transmitter is a loop-powered 4-20mA transmitter with a wide range of useful features

and programmable options. Five buffer choices are available in two-point calibration mode. The 4-20mA output is scaleable in pH or mV units and has 500V input to output isolation. Temperature is always displayed and is selectable in degrees C or deg F. All stored parameters and calibration data are retained in the non-volatile memory during transmitter power down or power loss. A useful probe clean reminder icon flashes when it is time to clean the probe. Probe cleaning interval is user programmable from 1 to 250 days. The TX100 can be used for wall mounting, panel mounting, pipe mounting and DIN-rail mounting. Cable grips for inlet/outlet to box are included as well as all mounting hardware. The case meets NEMA and IP ratings for water resistance.
