Digital signal converter / frequency-to-current / for potentiometers / galvanically-isolated

In industry is very often required to collect many system variables i.e. pressure, temperature or pH. For this purpose are usually used devices which we can call data converters. These converters use for communication usually current loops. There is a few variants of current loop transceiver, i.e. from-the-loop powered current transceiver. The current of current loop is usually between 4 and 24 mA. Non-zero current provides advantage of detection of broken lead.
Advanced potentiometric converter MPH71
MPH 71This converter is maily designed to cover needs of most of our customers to potentiometric metering. Basic control is suitable for operating in industry, where is converter set up only once and then only calibration of electrode is made periodically. Minimum of controlling buttons provides sure advantage of hard set sensitive parameters of conversion, which is not possible to modify by common manipulation.
Key features

Isolated from-the-loop powered current loop transceiver 4-20mA.
Fully configurable via RS-232.
RS-232 is galvanically isolated from measuring part and current loop.
Measures mV, pH and concentration.
Wide input voltage range (± 2,3V), so it is suitable for REDOX measurement too.
Temperature compensation of pH
Two point and three point calibration for pH and concentration
Simple control for calibration.
