Loop-Powered 4-20mA Transmitter for Use with pH and ORP Electrodes and Sensors, Sensorex TX100 pH/mV

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. Measuring Range (pH): 0.00 to 14.00pH, 0.01 pH resolution, +/- 0.01 accuracy. Measuring Range (ORP/mV): -1999mV to 1999mV, 1mV resolution, +/- 2mV accuracy. Temperature Range: -20 to 110 degree C, 0.1 deg C/F resolution. Current Output Range: 2.00mA - 24mA , .01mA resolution, +/- 0.005mA accuracy, 500V input/output isolation. Enclosure: NEMA 4X IP65, ABS case with pushbutton control pad HWD: 3.9” x 3.9” x 2.9”.
