Converters for industry

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.

Potentiometric converter MPH71

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.

Documentation MPH71

Panel conveter MPH72

It is re-made variant of MPH71. for panel mounting and suplying by 24V. It has quite small dimensions: 96x46 mm, montage depth 80 mm. It has LED display, so the value is always perfectly readable. Converter setup could be accomplished using RS232 interface. Measuring part of MPH72 is galvanically separed from the rest of the device. Calibration could be performed from the front panel using two buttons.
