Description

PHC20 is a reliable conductivity transmitter, enclosed in a small housing for DIN-rail mounting or in box mounting, especially designed for clear, industrial, and sea water applications. It is compatible with COMECO’s conductivity probes series CSK as well as other 2-electrode contacting conductivity cells within conductance range from 0.1 µS to 100 mS/cm, and has an additional Pt100, Pt1000 or NTC 1k input for automatic temperature compensation. The transmitter provides linear current or voltage output and can also be equipped with a relay alarm/control output. All device parameters (preset conductance ranges, analog output range and direction, relay set point, hysteresis, and direction, temperature compensation parameters, etc.) are user-programmable via the RS232 interface.. Thanks to its wide measurement range, flexibility, programmability, and reliability, the PHC20 transmitter is very suitable for water treatment and processing applications in the food, pharmaceutical, and many other industries.
