Transmitter/Controller Specifically designed for drinking and wastewater treatment plants, the MicroChem® is able to measure up to three of the following parameters: pH, ORP, Chlorine, Chlorine Dioxide, Conductivity, and 4-20 mA. The MicroChem® can be configured as an Analyzer/
Transmitter or a Controller. MicroChem® products are available packaged as a complete residual analyzer or as individual components allowing flexible configurations to meet specific customer needs.
Analyzer/Transmitter – The MicroChem® is capable of accepting signal(s) from up to three sensors representing a wide variety of measurements.
Controller – The MicroChem® can provide control of the measured parameter using a standard PID algorithm in conjunction with the sensor input signal, or as a PID Compound Loop controller utilizing the signal from the sensor and an optional 4-20 mA process flow signal. Two outputs are available from each channel card. One control output is available both as a 4-20 mA control signal or a pulse width modulation output. A second software configurable 4-20 mA output signal is available on each configured channel.
Additional parameters can be measured with the MicroChem® Instrument. 12 mm probes are available for use in select measure cells or in a stand-alone 12 mm flow cell. Insertion probes are available for direct tank mounting or into a 3/4″ NPT pipe fitting. Consult the probe parts lists and price pages for available cable lengths and mounting options.
12 mm Probes:
The 12 mm probes can be installed in the KC4, CL4, CL1 measure cells or in a stand-alone flow cell. Most pH probes include built-in temperature sensor that compensates for changes in sample temperatures. The only exception are the probes used with the KC4 that utilize the temperature
sensor included with this cell. ORP probes do not utilize temperature compensation and are not provided with built-in temperature sensors.
Immersion Probes:
Immersion probes are mounted inside a robust Ryton housing. Immersion probes can be mounted directly to a 3/4″ NPT pipe connection or submerged into a tank. The probes have flat surface electrodes that provide a self-cleaning action as the fluid sample passes over the element. pH and Conductivity probes include a built-in temperature sensor to allow compensation of the measurement as the sample temperature changes. ORP probes do not utilize temperature compensation and are not provided with built-in temperature sensors.
