Liquid analysis sensor / transmitter : pH, conductivity, ORP dissolved oxygen
PHT
Comeco Control & Measurement
♦ 4 design variants
♦ High input impedance - over 1013 Ω
♦ Standard current or voltage output signal
♦ Automatic temperature compensation
The PHT transmitter converts the high impedance voltage output of pH
or REDOX (ORP) probes into standard current or voltage signal that can be
safely sent over longer distances. The transmitter provides the necessary
for the normal pH/ORP probe's operation high input impedance as well as
temperature compensation of pH measurement through a Pt100 temperature
sensor connected to the second transmitter input. Four variants are available
differing by power supply, output signal, type of mounting, and protection
class. The PHT transmitter is applicable in all cases in which there is a need
for measuring pH or ORP and the measurement signal has to be sent over
relatively long distance from the point of measurement.
